Safety Instructions, Warnings, and Notes
2.Safety Instructions, Warnings, and Notes
Index of this chapter:
2.1 Safety Instructions
2.2 Maintenance Instructions
2.3 Warnings
2.4 Notes
2.1Safety Instructions
Safety regulations require that during a repair:
•Due to the chassis concept, a very large part of the circuitry
(incl. deflection) is 'hot'. Therefore, connect the set to the
mains via an isolation transformer.
•Replace safety components, indicated by the symbol h,
only by components identical to the original ones. Any
other component substitution (other than original type) may
increase risk of fire or electrical shock hazard.
•Wear safety goggles when you replace the CRT.
Safety regulations require that after a repair, you must return
the set in its original condition. Pay, in particular, attention to
the following points:
•General repair instruction: as a strict precaution, we advise
you to re-solder the solder connections through which the
horizontal deflection current is flowing. In particular this is
valid for the:
1. Pins of the line output transformer (LOT).
2. Fly-back capacitor(s).
3. S-correction capacitor(s).
4. Line output transistor.
5. Pins of the connector with wires to the deflection coil.
6. Other components through which the deflection current
flows.
•The maintenance inspection includes the following actions:
1. Perform the 'general repair instruction' noted above.
2. Clean the power supply and deflection circuitry on the
chassis.
3. Clean the picture tube panel and the neck of the picture
tube.
2.3Warnings
•In order to prevent damage to ICs and transistors, avoid all
high voltage flashovers. In order to prevent damage to the
picture tube, use the method shown in Fig. 2-1, to
discharge the picture tube. Use a high voltage probe and a
multi-meter (position V
reading is 0 V (after approx. 30 s).
V
Figure 2-1 Discharge picture tube
). Discharge until the meter
DC
E_06532_007.eps
250304
Note: This re-soldering is advised to prevent bad connections
due to metal fatigue in solder connections, and is therefore only
necessary for television sets more than two years old.
•Route the wire trees and EHT cable correctly and secure
them with the mounted cable clamps.
•Check the insulation of the mains cord for external
damage.
•Check the strain relief of the mains cord for proper function,
to prevent the cord from touching the CRT, hot
components, or heat sinks.
•Check the electrical DC resistance between the mains plug
and the secondary side (only for sets that have an isolated
power supply). Do this as follows:
1. Unplug the mains cord and connect a wire between the
two pins of the mains plug.
2. Turn on the main power switch (keep the mains cord
unplugged!).
3. Measure the resistance value between the pins of the
mains plug and the metal shielding of the tuner or the
aerial connection of the set. The reading should be
between 4.5 MΩ and 12 MΩ.
4. Switch the TV 'off' and remove the wire between the
two pins of the mains plug.
•Check the cabinet for defects, to prevent the possibility of
the customer touching any internal parts.
2.2Maintenance Instructions
•All ICs and many other semiconductors are susceptible to
electrostatic discharges (ESD, w). Careless handling
during repair can reduce life drastically. Make sure that,
during repair, you are connected with the same potential as
the mass of the set by a wristband with resistance. Keep
components and tools also at this potential. Available ESD
protection equipment:
– Complete kit ESD3 (small tablemat, wristband,
connection box, extension cable and ground cable)
4822 310 10671.
– Wristband tester 4822 344 13999.
•Together with the deflection unit and any multi-pole unit,
flat square picture tubes form an integrated unit. The
deflection and the multi-pole units are set optimally at the
factory. We do not recommend adjusting this unit during
repair.
•Be careful during measurements in the high voltage
section and on the picture tube.
•Never replace modules or other components while the unit
is 'on’.
•When you align the set, use plastic rather than metal tools.
This will prevent any short circuits and the danger of a
circuit becoming unstable.
2.4Notes
2.4.1General
We recommend a maintenance inspection carried out by
qualified service personnel. The interval depends on the usage
conditions:
•When a customer uses the set under normal
circumstances, for example in a living room, the
recommended interval is three to five years.
•When a customer uses the set in an environment with
higher dust, grease, or moisture levels, for example in a
kitchen, the recommended interval is one year.
•Measure the voltages and waveforms with regard to the
chassis (= tuner) ground (H), or hot ground (I), depending
on the tested area of circuitry.
•The voltages and waveforms shown in the diagrams are
indicative. Measure them in the Service Default Mode (see
chapter 5) with a colour bar signal and stereo sound (L: 3
kHz, R: 1 kHz unless stated otherwise) and picture carrier
at 475.25 MHz (PAL) or 61.25 MHz (NTSC, channel 3).
Page 5
Directions for Use
EN 5DPTV565 AA3.
•Where necessary, measure the waveforms and voltages
with (D) and without (E) aerial signal. Measure the
voltages in the power supply section both in normal
operation (G) and in standby (F). These values are
indicated by means of the appropriate symbols.
•The picture tube panel has printed spark gaps. Each spark
gap is connected between an electrode of the picture tube
and the Aquadag coating.
•The semiconductors indicated in the circuit diagram and in
the parts lists, are interchangeable per position with the
semiconductors in the unit, irrespective of the type
indication on these semiconductors.

4.3Picture Tube Replacement
Replacement of the cathode ray tube (CRT) and/or optical
system components of a Projection TV (PTV) can be easily
accomplished by following general guidelines. Use care when
working around the CRT and optical systems of the PTV. The
PTV light path encompasses a number of precision optical
components. These include lenses, mirrors, the lenticular
screen, and Fresnel lens. The PTV incorporates three separate
CRTs, representing green, red, and blue outputs. Each CRT
uses an independent deflection/convergence yoke, magnetic
centring ring, coupler, C-element lens, and output lens (A/B
lens). Each tube is mechanically fastened to a coupler which
houses fluid (a glycol-type substance) used to cool the high
temperatures generated by the small (7") CRTs. The fluid also
provides an optical characteristic supporting the optical system
of the PTV. When replacement of a CRT or optical component
is required, caution must be exercised in preventing fluid
spillage. The technician must carefully reassemble the CRT/
optical components, ensuring a proper seal of the coupling
fluid. Use only factory original coupling fluid.
Caution: Do not use or add water as an alternative to the
prescribed coupling fluid.
Note: Upon completion of CRT/optical assembly repair, the
centring, convergence, grey scale, mechanical and electrical
focus adjustments are required. If more than one assembly
requires repair, it is recommended the service technician fully
complete one assembly at a time, using the existing
assemblies as a reference for the alignment of the centring and
convergence.
The following procedure should be used when performing
repairs on the CRT/optical assemblies of the Projection TV.
4.3.1Disassembly Procedure
A. Removal of a single CRT/Lens Assembly from the light
rack
1. Remove AC power from the PTV.
2. Remove the upper and lower back covers (1/4" screws).
3. Remove the barrier board and the shield cover from around
the lens assemblies (1/4" screws).
4. Carefully remove the CRT Socket Board from the CRT of
the CRT/optical assembly being serviced.
5. Remove the yoke and convergence plugs, of the CRT/
optical assembly being serviced, from the Large Signal
Module.
6. Remove the high voltage anode lead from the HV splitter
block on the Large Signal Module of the CRT/optical
assembly being serviced. Remove ground lug connectors
from the coupler frame.
7. Remove the four 1/4" screws that secure the CRT/lens
assembly to the light rack. These four screws are located
in each corner, on the top of the coupler assembly.
Caution: Do not remove the bolts with pressure springs or
the inverted Torx screws of the CRT/lens assembly. The
removal of these components could result in fluid spillage
into the PTV cabinet.
8. Carefully remove the CRT/Lens assembly from the PTV
cabinet.
4.3.2Servicing the CRT/Lens Assembly
Warning: Coupling fluid is a poisonous solution containing a
high concentration of ethylene glycol. Do not leave exposed
fluid unattended. Prevent children or pets from coming into
contact with the fluid. Clean up spills immediately.
Caution: Do not attempt any repairs on the CRT/optical block
assembly without first removing the CRT coupling fluid.
Removal of the delta output lens will result in spillage of the
coupling fluid.
B. Removing the PTV Coupling Fluid
All repairs made to the CRT/optical block assembly require the
removal of the coupling fluid. The following procedure
describes how to remove the PTV coupling fluid.
1. Lay the CRT assembly on its side with the plug pointing up.
2. Remove the plug (X8).
3. Remove some of the fluid from the coupler to prevent
spillage when the CRT is removed. An empty coupling fluid
bottle with a cone top is recommended to lower the fluid
level within the coupler. Squeeze and hold the bottle and
insert the tip of the cap into the drain hole of the coupler.
Loosen the grip on the bottle, allowing the fluid to be pulled
up into the bottle. Save the fluid.
4. Reinstall the plug (X8).
5. Stand the CRT assembly up with the neck of the CRT
pointing up.
6. With an awl or marking pen, outline the edges of the CRT
onto the coupler.
Note: The correct positioning of the CRT to the coupler is
critical to the optimum performance of the optical system.
7. Remove the four CRT mounting bolts (A) (with springs and
spacers) and remove the mounting bracket (D).
8. Remove the four CRT mounting ear screws.
Note: The CRT mounting ear screws are not used on some
assemblies.
9. Gently remove any metal shavings from around the screw
holes. Do not allow the metal shavings to get into the fluid.
Note the position of the high voltage anode cap with
respect to the coupler.
10. Carefully remove the CRT from the coupler. Wipe any
excess fluid from the faceplate of the CRT. Set the CRT
aside.
11. Use an empty coupling fluid bottle to extract the remainder
of the fluid from the coupler.
Note: Complete removal of the coupling fluid is not
necessary when only replacing the CRT.
12. Clean any remaining fluid from the coupler and the CRT
gasket channel using absorbent tissue. Refer to "C".
Cleaning the Coupler, C-element Lens, and CRT
Faceplate procedure if the fluid is discoloured or
contaminated.
13. Make all necessary repairs.
C. Cleaning the Coupler, C-Element Lens, and CRT
Faceplate
1. Remove CRT coupling fluid as described in steps B1
through B13.
2. Using denatured alcohol on a cloth made of 100% cotton
or a lens cleaning tissue, gently clean the C-element
(fisheye) lens, coupler and the CRT faceplate. Thoroughly
clean the coupler assembly, including the expansion
chamber bladder, and allow to fully dry.
Caution: Do not use soap or detergent type substances to
clean the coupler and its related assemblies. Water can be
used as an alternative to denatured alcohol, but the
assemblies must be completely dry before reassembly of
the coupler and the addition of the coupling fluid. A hair

dryer may be used to dry the coupler and its assemblies
before reassembly. If contaminated fluid is discovered, the
coupler and its related assemblies must be completely
disassembled and cleaned to prevent a reoccurrence.
3. Replace the CRT and C-element lens gaskets.
4. Reassemble the C-element lens and the output lens to the
coupler.
5. Refer to "Replacing the CRT Coupling Fluid" upon
completion of necessary repairs and cleaning of the
optical/coupler assemblies.
D. Replacement of the CRT
1. Remove CRT coupling fluid as described in steps B1
through B13.
2. Remove the plastic protective coating (if present) from the
faceplate of the replacement CRT.
3. Refer to "Replacing the CRT Coupling Fluid" to complete
the CRT replacement.
E. Repair or Replacement of the Optical/Coupler Assembly
1. Remove CRT coupling fluid as described in steps B1
through B13.
2. Remove the four inverted-type Torx screws, which secure
the Delta output lens to the coupler. An inverted-type Torx
socket can be purchased using part number 4835 395
17303.
3. Removal of the Delta output lens will allow access to the Celement lens, C-element gasket, coupler, and its
assemblies.
4. Refer to "Replacing the CRT Coupling Fluid" upon
completion of necessary repairs to the optical/coupler
assemblies.
the top of the coupler at the plug. Wipe any excess fluid
from around the coupler.
11. Reinstall the plug and check for any fluid leaks.
12. Install the repaired CRT/optical block assembly into the
PTV and perform any necessary adjustments.
4.4Set Re-assembly
To re-assemble the whole set, execute all processes in reverse
order.
Note: While re-assembling, make sure that all cables are
placed and connected in their original position
F. Replacing the PTV Coupling Fluid
Notes:
•Before replacing the CRT coupling fluid, ensure the
expansion chamber bladder is fully collapsed. This can be
easily inspected by viewing the bladder through the small
hole on the expansion chamber assembly. If the rubber of
the bladder is not easily visible through the small hole, then
the bladder may be considered collapsed and fluid can be
added. If the rubber of the expansion chamber bladder is
visible at the hole of the expansion chamber, then
replacement of the expansion chamber bladder is required.
•The CRT coupling fluid is critical to the optical performance
of the PTV. Use only part number 4835 310 67032 (3 bottle
kit) or 4835 310 67031 (1 bottle) to ensure the optical
integrity and performance reliability of the PTV when
replacing the CRT coupling fluid.
1. Reinstall the CRT gasket into the gasket channel of the
coupler. Confirm the placement of the CRT, C-element
lens, and vent plug gaskets.
2. Place the CRT onto the coupler with the high voltage
anode lead positioned as marked in step 10 of procedure
B.
3. Carefully position the CRT onto the coupler, using the
outline defined in step 6 of procedure B as a reference.
4. Start the CRT mounting ear screws but do not tighten
them.
5. Tighten the CRT mounting ear screws in a star pattern (like
tightening lug nuts on the wheel of a car). Make sure the
CRT does not shift position from the outline defined in step
B6.
Caution: do not over tighten the CRT ear screws (the CRT
mounting ear screws are not used on some assemblies).
6. Install the CRT mounting bracket and start the four CRT
mounting bracket bolts with springs.
7. Tighten the bolts in a star pattern.
8. Lay the CRT assembly on its side with the plug pointing up.
9. Remove the plug.
10. Using the PTV coupling fluid bottle with the cone top, refill
the coupler with fluid through the drain access hole.
Completely fill the coupler chamber so the fluid is level with

5.2.1Service Default Mode (SDM)
Introduction
The Service Default Mode (SDM) is a technical aid for the
service technician. The Service Default Mode (SDM)
establishes fixed, repeatable settings of customer controls,
which allow consistent measurements to be made. The SDM
also initiates the blinking LED procedure and, if necessary,
overrides the 5 V protection.
The SDM places the set in the following pre-defined conditions:
•Tuning frequency set to 475.25MHz.
•Volume level set to 25% (of the maximum volume level).
•Other picture and sound settings set to 50% (mid-range).
The following functions are turned OFF while in SDM:
•Timer
•Sleep timer
The following functions are disabled during SDM (and enabled
after leaving SDM):
•Parental lock
•Blue mute
•Hospitality Mode
•No-ident Timer (normally the set is automatically switched
off when no video signal (IDENT) is received for 15
minutes).
All other controls operate normally.

5.4ComPair
5.4.1Introduction
When this is not the case, ComPair will guide you through
the fault finding tree by asking you questions (e.g. Does the
screen give a picture? Click on the correct answer: YES /
NO) and showing you examples (e.g. Measure test-point I7
and click on the correct oscillogram you see on the
oscilloscope). You can answer by clicking on a link (e.g.
text or a waveform picture) that will bring you to the next
step in the fault finding process.
By a combination of automatic diagnostics and an interactive
question / answer procedure, ComPair will enable you to find
most problems in a fast and effective way.
Beside fault finding, ComPair provides some additional features like:
•Up- or downloading of pre-sets.
•Managing of pre-set lists.
•Emulation of the (European) Dealer Service Tool (DST).
•If both ComPair and Force/SearchMan (Electronic Service
Manual) are installed, all the schematics and the PWBs of
the set are available by clicking on the appropriate
hyperlink.
Example: Measure the DC-voltage on capacitor C2568
(Schematic/Panel) at the Mono-carrier.
– Click on the “Panel” hyperlink to automatically show
the PWB with a highlighted capacitor C2568.
– Click on the “Schematic” hyperlink to automatically
show the position of the highlighted capacitor.
5.4.3How to Connect
ComPair (Computer Aided Repair) is a service tool for Philips
Consumer Electronics products. ComPair is a further
development on the European DST (service remote control),
which allows faster and more accurate diagnostics. ComPair
has three big advantages:
•ComPair helps you to quickly get an understanding on how
to repair the chassis in a short time by guiding you
systematically through the repair procedures.
•ComPair allows very detailed diagnostics (on I
is therefore capable of accurately indicating problem areas.
You do not have to know anything about I
yourself because ComPair takes care of this.
•ComPair speeds up the repair time since it can
automatically communicate with the chassis (when the
microprocessor is working) and all repair information is
directly available. When ComPair is installed together with
the Force/SearchMan electronic manual of the defective
chassis, schematics and PWBs are only a mouse click
away.
5.4.2Specifications
ComPair consists of a Windows based fault finding program
and an interface box between PC and the (defective) product.
The ComPair interface box is connected to the PC via a serial
(or RS232) cable.
For this chassis, the ComPair interface box and the TV
communicate via a bi-directional service cable via the service
connector(s).
The ComPair fault finding program is able to determine the
problem of the defective television. ComPair can gather
diagnostic information in two ways:
•Automatic (by communication with the television): ComPair
can automatically read out the contents of the entire error
buffer. Diagnosis is done on I

Service Modes, Error Codes, and Fault Finding
5.5Error Codes
5.5.1Introduction
The error code buffer contains all errors detected since the last
time the buffer was erased. The buffer is written from left to
right. When an error occurs that is not yet in the error code
buffer, the error code will appear at the left side and all other
errors shift one position to the right.
5.5.2How to Read the Error Buffer
Use one of the following methods:
•On screen via the SAM (only possible when you have a
picture). Examples:
– ERR: 0 0 0 0 0 0 0 : No errors detected.
– ERR: 6 0 0 0 0 0 0 : Error code 6 is the last and only
detected error.
– ERR: 9 6 0 0 0 0 0 : Error code 6 was first detected and
error code 9 is the last detected (newest) error.
•Via the "blinking LED" procedure, if no picture is available.
See explanation of "The blinking LED procedure" below.
5.5.3How to Clear the Error Buffer
The error code buffer will be cleared in the following cases:
•By activating "CLEAR ERRORS" in the SAM menu.
•By exiting SDM or SAM with the "Standby" command on
the remote control.
•Upon automatic reset, when the content has not changed
for 50 consecutive hours.
Note: By leaving SDM or SAM via the Mains switch, the error
buffer will not be reset.
5.5.4Error Codes
In case of non-intermittent faults, clear the error buffer before
starting the repair. This to ensure that "old" error codes are no
longer present. Before clearing the buffer, write down the
content, as the history can give you valuable information. If
possible, check the entire content of the error buffer. In some
situations, an error code is only the result of another error code,
and not the actual cause (e.g. a fault in the protection detection
circuitry can also lead to a protection).

Service Modes, Error Codes, and Fault Finding
5.6The ”Blinking LED” Procedure
5.6.1Introduction
The contents of the error buffer can also be made visible
through the "blinking LED" procedure. This is especially useful
when there is no picture.
When the SDM is entered, the LED will blink the number of
times equal to the value of the error code.
– The ON/OFF indicator going out for 500 ms precedes all
error code sequences. (There is a possibility of up to 10.)
– After the 500 ms delay, the ON/OFF indicator will slowly
flash the first number of the first code.
– This immediately follows by rapid flashes for the second
number in the first code. If an error code is smaller than 10,
the ON/OFF indicator will rapidly flash 1-9 times to indicate
the code. (EXP. Six rapid flashes indicate an error code of
6.)
– There will be a delay of approximately 3 seconds between
codes.
– For error codes of 10 and higher, the ON/OFF indicator will
slowly flash the correct number of times to indicate the first
digit, and will then rapidly flash the correct number of times
to indicate the second digit. (EXP. Three slow flashes
followed by six rapid flashes indicate an error code of 36.)
– When all error-codes are displayed, the sequence is
finished and the ON/OFF indicator turns OFF for 300 ms.
At this point the sequence will begin again as indicated by
the ON/OFF indicator turning ON for 300 ms and repeating
all error codes.
Example: 112 024 036 0 0
After entering SDM:
– The sequence will begin by the ON/OFF indicator turning
off for 500 ms.
– Then slowly blink 11 times followed by two rapid blinks
(indicating error code 112).
– Next the LED will pause for 300 ms followed by 2 slow
blinks follow by 4 rapid blinks, (indicating error code 024).
– Next the LED will pause for 300 ms, then slowly blink 3
times followed by 6 rapid blinks (indicating error code 36).
– Then pause 300 ms ending the sequence in this example.
– If there were error codes in positions 4 and 5, those
sequences would also be given.
Note: If errors 1, 2, 3, or 4 occur, the LED always blinks
indicating the last error that occurred, even if the set is not in
service mode.
Checking the Screen voltage from the Focus G2 block will
indicate whether the High voltage circuit is working or not.
Horizontal and Vertical drive from the HOP panel must be
present for the High voltage to be present. Horizontal drive
should be present on Pin 9 of 1510 and Vertical drive should be
present on Pin 3.
5.7.3No Picture
If Audio is present but there is no Picture, press the Index
button on the Remote control. If OSD is present, High voltage
is working and the CRT drive circuits are working. If the signal
is NTSC, YUV from the SSM is fed to the HOP on connector
1250. YUV from the SSB can be checked on Pins 25, 24, and
23 of connector 1020.
5.7.4 No Audio
The Audio amplifier is located on the SSM. The Audio is
powered by a supply located on the Large Signal panel. This
voltage can be checked on Pins 10 and 11 of connector 1516.
These voltages will measure a plus 23 and a minus 23 Volts.
Speaker output can be checked on connector 1349. A Centre
Channel Amp switch panel will be present on the Core models
5.7Trouble Shooting Tips
5.7.1Introduction
Before the set can be repaired to a component level, it is
necessary to determine which board is defective. The Wiring
interconnect diagram is a useful tool for this (see chapter 6).
5.7.2Dead Set
The Standby Power supply and Rectifiers are located on the
Input panel. Control for power On/Off is performed by the
Microprocessor located on the SSB. This Processor is powered
by the 5 Volt standby voltage from the Input Panel. For a Dead
Set condition, check the 5 Volt standby supply on Pin 1 of 1102.
If this voltage is present, check the Standby line on Pin 3. This
line will be approximately 2.6 Volts in standby and zero Volts
when the set is turned "on". If the Standby line goes Low, check
the 130 Volt source on Pin 8 of connector 1518. If this voltage
is present, the Full Power supply on located on the Large
Signal panel is working. If the Picture is not present but audio
is, the High voltage or video drive circuits may have failed.

TUNER AGC
1. Connect the RF output of a video pattern generator to the
antenna input.
2. From the generator, input a PAL B/G TV signal with a
signal strength of approximately 2 mV and a frequency of
475.25 MHz (PAL) or 61.25 MHz (NTSC).
3. Measure the DC voltage on pin 1 of the (main) Tuner. You
can adjust this voltage by adjusting the TUNER AGC item
in the SAM menu. Alignment is correct when the DC
voltage is just below 3.5 V.
IF AFC TUNER 2 (if present)
Use the same procedure as described above (under IF AFC)
with the set switched to the DW source.
IF LPRIME AFC TUNER 2 (if present)
Use the same procedure as described above (under IF
LPRIME AFC) with the set switched to the DW source.
TUNER AGC TUNER 2
Use the same procedure as described above (under TUNER
AGC) with the set switched to the DW source. Measure on pin
“1” of the DW Tuner.
BLEND INTENSITY
Use this alignment when you replace the microcontroller or the
HOP. It aligns the level of transparency of the menu-picture
blended into the main-picture.
Position the "Brightness", "Contrast", and "Colour" setting in
the middle position (in the customer "Picture" menu).
1. Apply a signal with a 100 % white video pattern (white
raster).
2. Connect an oscilloscope to pin 8 of connector 1298 of the
CRT panel and measure the Red output level.
3. Align the BLEND INTENSITY parameter so that the
blended signal is 65 % of the black-white amplitude. This
will be about 1.3 V (blended signal) versus 2 V (full white
signal).
4. The parameter can be adjusted from 0 to 31.
8.3.2LUM. DEL. (Luminance Delay)
With this alignment, you place the luminance information
exactly on the chrominance information (brightness is pushed
onto the colour). Use a colour bar / grey scale pattern as test
signal.
•LUM. DELAY PAL BG: Apply a PAL BG colour bar / grey
scale pattern as a test signal. Adjust this parameter until
the transients of the colour part and black and white part of
the test pattern are at the same position. Default value is
"9".
•LUM. DELAY PAL I: Apply a PAL I colour bar/grey scale
pattern as a test signal. Adjust this parameter until the
transients of the colour part and black and white part of the
test pattern are at the same position. Default value is "9".
•LUM. DELAY SECAM: Apply a SECAM colour bar/grey
scale pattern as a test signal. Adjust this parameter until
the transients of the colour part and black and white part of
the test pattern are at the same position. Default value is
"11".
•LUM. DELAY BYPASS: apply a NTSC colour bar/
greyscale pattern as a test signal. Adjust this value until the
transients of the colour and black and white part of the test
area are at the same position. Default value is "10".
8.3.3 GDE SAM
Specifications:
•Set display mode in service mode.
•Service blanking.
•Set geometry.
•Preset picture.
•Set white tone.
•Convergence disable for setting geometry.
The GDE SAM mode (GDE = Generic Display Engine), allows
the Service Technician to set Geometry and White Tone (Grey
Scale). This mode is controlled by the GDE microprocessor
located on the ASC module. These settings are stored in an
EEPROM located on the ASC module. The GDE SAM displays
the Software version of the GDE microprocessor and the GDE
Errors.
There are three settings for Geometry in the 4x3 aspect ratio
sets and two for the 16x9 aspect ratio sets.
The signal for the 480p mode can be applied to the set via the
HD YPbPr inputs or from the SSB when the set is in the NTSC
mode. All Geometry alignments for this mode should be done
with an NTSC signal selected.
Adjustments for the 1080i should be done with an HD 1080i
signal applied to the set. The 4x3 aspect ratio sets have both a
Full and Compressed mode that requires alignment.
The Service Blanking selection (SERV BLANK) will blank the
bottom half of the picture. This selection is useful when
adjusting the Yokes to level the picture.
The Clamp Pulse should be set to Normal for a 480p or NTSC
signal. It should be set to 1080i for an HD signal.
The Convergence Processor selection will enable or disable
Convergence drive. Convergence should be disabled when
performing Cantering or Geometry alignments.

requiring further adjustment.
Note: Perform (and store) Convergence alignment after any
changes to the Geometry.
8.4.4Convergence Mode
There are two new screen sizes for the AP region incorporating
a Digital Convergence system using 208 adjustment points.
The Convergence Processor is located on the ACS (Automatic
Convergence System) module. The Convergence drive circuits
are located on the SSP (Small Signal Panel). Data for the
Convergence and Geometry settings are stored in the
EEPROM located on the ACS module.
If the CRTs, the Large Signal Panel (LSP), or the Small Signal
Module (SSM) are changed, a complete Geometry and
Convergence alignment will be necessary.
If the ACS module, the Small Signal Panel (SSP), or CRTs are
changed, a complete Convergence alignment will be
necessary.
To obtain the correct Geometry during Convergence, a
template must be used. There are eight Geometry and
Convergence settings, stored in the EEPROM on the ACS
Module.

8.4.8Green Geometry
Important: Do not make changes to the Green Geometry
without placing a Template over the screen.
The Green Geometry must be done first when performing a
complete convergence alignment. A Screen Template is
necessary to obtain the correct geometry. Failure to use the
Screen Template or mis-adjustment of the convergence will
result in reduced life of the Convergence amplifiers.
Figure 8-3 Screen shot of "Green geometry" adjustment
Place the Screen template on the TV screen. Select GREEN in
the selection menu. The Cursor will appear in the centre of the
screen as shown in the picture.
When the ACS module has been replaced, it would be
advisable to load Default settings. Press the MENU button to
adjust, and then use the Cursor buttons to move the Green
cross onto the Template.
The adjustment of the cross has two-step sizes: large and
small. Press the MENU button to toggle between the two.
After a point has been adjusted, press the Index button to
return to Navigate. When Default settings have been loaded,
the left most line that is not visible should be adjusted first.
Adjust the Vertical line 0 while observing line 1 to make line 1
parallel with the left edge of the screen. The adjustment should
only be made in small steps.
Do not adjust any one point more than 1/4 the distance of one
grid in each pass. After the left most line is adjusted, start at the
centre left of the screen and work to the right, aligning the
Horizontal lines. When adjusting the Horizontal lines, best
results are obtained when working from left to right.
After the Centre line is adjusted, go to the next line down until
all of the lines have been adjusted, then work from the centre
up to adjust the Horizontal lines. Using the same method, work
from centre out to adjust the Vertical lines. At least three
passes will be necessary to complete the alignment. Press the
Index button to return to the selection menu.
When the GREEN geometry is complete, STORE the data.
Remove the template from the screen. Select RED TO GREEN
in the selection menu. Using the same method that was used
to adjust the Green Grid to the Template, adjust the Red Grid
onto the Green Grid. If the set is a later production, select SP
RED to centre the Red grid onto the Green grid. Exit this mode
by pressing the MENU button. Then select the MP RED to
adjust the Red onto the Green using the 35-point adjustment.
When this is complete, select the RED TO GREEN to perform
the 208-point adjustment.
When the RED TO GREEN is complete, select the BLUE TO
GREEN, using the same alignment method as the RED TO
GREEN.
Select STORE to save your the alignments after adjusting each
colour. Each time data is stored; the Intellisense circuit will
recalculate the position of the four sensors in the set.
Exiting the Convergence Mode without saving will cause the
alignments to be lost.
Repeat the adjustment for each of the remaining modes.

8.5Option Settings
8.5.1Introduction
The microprocessor communicates with a large number of I2C
ICs in the set. To ensure good communication and to make
digital diagnosis possible, the microprocessor has to know
which ICs to address. The presence / absence of these specific
ICs (or functions) is made known by the option codes.
Notes:
•After changing the option(s), save them with the STORE
command.
•The new option setting is only active after the TV is
switched "off" and "on" again with the Mains switch (the
EAROM is then read again).

9.1Introduction
Two new chassis are being introduced for the Asia Pacific
region in the 2005 model year. The table below lists the Model
and Chassis numbers.
All the chassis have multi-system tuning capability. The set has
the capability of displaying the 1080i, 480p, and 576p high
definition component analogue inputs. The 1fH RF inputs can
be PAL or SECAM. The 1fH AV inputs can be YPbPrcomponent, composite, or SVHS.
Some of the highlights are:
•TV-off air systems (PAL and SECAM).
•Korean sets NTSC only.
•NTSC (3.58 - 4.5 MHz).
•NTSC (4.43 - 5.5 MHz).
•PAL B/G, PAL D/K, PAL I, PAL M, PAL N.
•SECAM B/G, SECAM D/K, SECAM K1.
•HD signal inputs are analogue.
•Component in.
The sets have 1fH multi-system composite, SVHS, and
component inputs. The External 1fH or TV RF signals are fed
to the Picnic and Eagle circuits, where the user can select
between 100 Hz Digital Scan or Double lines.
External input systems:
•NTSC 3.58 MHz
•NTSC 4.43 MHz
•PAL
•SECAM
•480p, 576p, 1080i, component input
•480p, 1080i Korean set
All of the sets, based on the PEMG, have a 4x3 aspect ratio,
except the 46” version which has a 16x9 aspect ratio. There are
eight different scan modes with each requiring separate
geometry and convergence settings. The modes are PAL
100Hz, PAL 75 Hz, 576p, 576p DVD, 480p, 480p DVD, 1080i.
Each of the modes has separate geometry and convergence
data, stored in the NVM, located on the ACS (Automatic
Convergence System) module.
Sound System processing is performed on the SSB (Small
Signal Board). This is a multi-system sound decoding
processor. The audio amplifier is located on the SSM (Small
Signal Module). This is a 24 Watt (2 x 12 Watts) digital
amplifier. There is also a Headphone output, located on the
Side Jack Panel. The headphone amplifier is located on the
SSM.
Sound system:
•30 W (2x15W) Audio.
•Headphone Out.
•Speaker "on"/Off.
9.2Power Supplies
The Rectifiers and Standby Supplies are located on the AC
Input Panel. The Main Power Supply is located on the Large
Signal Board (LSB).
In the table below, the models are listed with their respective
voltage requirements. Auto Multi Voltage sets have a voltage
range of 90 to 276 V.

9.2.1Overall Power Supply Block
Figure 9-1 Power supply block diagram
The bridge rectifiers and Standby supply are located on the AC
Input Panel. The Main Power supply is located on the Large
Signal panel. A mains switch switches the AC power to the
bridge rectifier, located on the AC Input panel. This switch must
be turned "on", to place the set in the Standby mode. The
Standby supply produces a +5 Volt standby voltage. In the
Standby mode, the set consumes less than 1 W of power.
When the set is turned "on", the microprocessor on the SSB
causes the STANDBY line to go "low", switching the Standby
supply to produce +15 V, +9 V, and +5.2 V sources. It also turns
the Main Power supply "on", which produces the Audio, +35, 35, +22, -22, +130 V_S, and +130 V_HV supplies. The +130
V_S supply is for the Horizontal Output section. The +130
V_HV supplies power to the High Voltage section.

The AC power is fed to the AC Input panel. A 5 A fuse (item
1000), provides protection. Chokes 5000 and 5001 provide
filtering for the AC. The Mains switch is connected via
connectors 1104 and 1106. Resistors 1003, 1002, 1001, and
3011 provide protection against Line Surges in the non-China
sets. In the China sets, resistors 3009, 3014, 3013, and 3010
have been replaced with choke 5002 to provide additional AC
filtering.

Resistors 3009, 3014, 3013, and 3010 provide current limiting
when power is first applied to the set. Bridge 6000 rectifies the
voltage for the Main power supply. Start-up voltage for the Main
Power supply is taken from the neutral side of the AC line. Fuse
1004 provides protection for the Standby Power supply.

Figure 9-3 Standby power supply circuit
The Standby Supply provides the 5V_STANDBY voltage to the
set in the Standby mode. When the set is turned "on", it
provides the +15, +9, and +5.2 Volts supplies.
Standby B+ is applied to the Standby Switching regulator 7218
via pins 5 and 3 of 5202. An internal switch in 7218 charges
capacitor 2283 connected to pin 1 of the IC. When the charge
on 2283 reaches 5.8 Volts, the internal switch switches to
internal. The IC is now being powered by the charge on
capacitor 2283. The internal FET drives transformer 5202 until
the charge on capacitor 2283 reaches 4.8 Volts. The IC repeats
the cycle until the 5 Volt Standby voltage reaches the correct
E_15000_068.eps
151004
level. Shunt regulator 7212 then turns "on", turning opto
isolator 7213 "on". The operating voltage for 7218 is then
supplied by the rectified hot secondary voltage from pin 1 of
5202. The internal regulator keeps pin 1 at 5.8 Volts.
Regulation is accomplished by monitoring the 5 Volt standby
voltage. If the 5 Volt supply increases, shunt regulator 7212 will
conduct more, causing the resistance of the transistor inside
7218 to decrease. The sensing resistor, Re, inside 7218 will
sense the increase in current and reduce the "on" time of the
internal FET, which will lower the 5 Volt supply to the correct
level.
Page 81
Circuit Descriptions, List of Abbreviations, and IC Data Sheets
EN 81DPTV565 AA9.
In Standby, the-5 volt Standby voltage is the only voltage being
applied to the set. The +15, +9, and +5.2 Volt sources are
turned "off". When the set is turned "on", the Standby Line goes
Low, turning transistor 7214 "off", turning 7205 "on", which
turns 7215 "on". This switches the +15 Volt supply to the set.
The +15 Volt supply then switches transistors 7216 and 7217
"on" to switch the +9 Volt and +5.2 Volt supplies to the set.
When the +15UV (Under Voltage detection) line goes "high",
transistor 7220 will turn "on", which will turn 7205 "off". This will
cause 7215 to turn "off", switching the +15, the +9, and the +5.2
Volt supplies "off". This will cause the set to shut down.
When troubleshooting, check for the presence of the operating
voltage on pin 7 of 7218. This 160 volts if the applied voltage is
120 volts AC or 328 volts is then applied voltage is 230 Volts
AC. If the Feedback circuit is not working or the secondary is
overloaded, pin 7 will be pulsing. In this case, check the voltage
on pin 5 of 7213. This is the operating voltage for pin 1 of 7218.
Each time the 5VSTBY voltage reaches 5 Volts, 7212 should
turn "on". The feedback opto isolator 7213 can be checked by
applying 5 volts to the +5VSTBY line with AC power removed
from the set. Vary the 5- volt supply between 4 and 6 Volts
while checking the resistance between Pins 4 and 5 of 7213.

Under voltage Detection
E_15000_069.eps
151004
Figure 9-4 Under voltage detection circuit
If the 15-Volt supply drops below 11.2 Volts, transistor 7221 will
turn "off". The 5-Volt standby supply will be applied to the base
of 7220 (Figure " Standby power supply circuit") via resistors
3262 and 3263. This will cause the +15UV line to go "high". In
the Standby mode, the Standby line is "high" turning transistor
7222 "on". When the set is turned "on", 7222 turns "off".
Capacitor 2296 provides a delay to prevent the +15UV line
from going "high" before the +15V supply turns "on".
This circuit can be defeated by grounding the base of transistor
7220. When repairs are complete, this jumper should be
removed.
Figure 9-5 Main power supply circuit
The Main Power supply is located on the Large Signal panel.
The Main B+ voltage from the Input panel is applied to the Main
Power switching transistor, 7301, via Pins 6 and 8 of
transformer 5300. This voltage is protected by fuse 1300 and
filtered by choke 5330. The Standby line goes "low" when the
set is turned "on". Transistor 7309 is turned "off", which turns
7300 "on". This turns relay 1305 "on". The Start-up voltage is
applied to capacitor 2303 via resistor 3300. When 2303
charges to 14.5 Volts, the under-voltage lockout of 7302
connected to pin 1 is turned "on". Drive is output on pin 3 to the
switching FET, 7301. This signal drives 5300 to produce the
Main Power supply voltages. IC 7302 will continue to drive
E_15000_070.eps
151004
5300 until the charges on capacitor 2303 drop below 9.4 Volts.
The Under voltage Lockout of 7302 will then turn the output on
pin 3 "off" until 2303 again charges to 14.5 Volts. After several
start-up cycles, the operating voltage for 7302 is supplied by
pin 10 of 5300.
Regulation is accomplished by monitoring the 130V_S supply
via resistors 3324, 3350, 3323, and 3322. The feedback
voltage is applied to the Shunt Regulator 7304, which drives
the feedback opto-isolator 7303. The feedback voltage is
applied to pin 14 of 7302. The voltage is fed to comparator "C"
which is referenced to 2.5 Volts. This output of this comparator
Page 82
EN 82DPTV565 AA9.
Circuit Descriptions, List of Abbreviations, and IC Data Sheets
sets the reference voltage for comparator "B", which is
compared with the voltage on the source of 7301. This voltage
is developed when 7301 turns "on", causing current to flow
through resistors 3308 and 3309. If 7301 fails, Resistors 3308
and 3309 should be replaced. These are one percent tolerance
resistors.
The Main Power supply produces: +130 V, +35 V, +22 V, -22
V, -35 Volt, a plus audio supply, and a minus audio supply. The
Audio supply is a plus and minus 23 Volts. This supplies the
digital audio amplifier located on the SSM (Small Signal
Module).
When troubleshooting, notice that the Hot Ground for the Main
Power supply is separated from the main Hot Ground on the
AC Input Panel by Choke 5330. To ensure correct readings,
use the Hot Ground in the Main power supply. If the power
supply is overloaded or the operating voltage is missing, the
voltage on pin 1 of the IC should be changing between 9.4 and
14.5 Volts. Each time the voltage reaches 14.5 Volts, drive
should appear on pin 3 of the IC. If a voltage is present on pin
1 that is greater than 14.5 Volts and there is no drive on pin 3,
the IC should be replaced. If drive is present on pin 3, check for
drive on the Drain of 7301. If drive is present here, check for a
short on the 130 Volt lines, a problem in the feedback circuit, or
a problem with the operating voltage.
Power Fail Shutdown
E_15000_071.eps
151004
Figure 9-6 Power fail shutdown circuit
The +22 Volt supply is rectified by 6306 and the -22 Volt supply
is rectified by 6307. The voltage on pin 18 of 5300 is monitored
to detect a failure of the AC supply to the set. This circuit
signals the microprocessor in the event that AC is removed
from the set while it is turned "on". The voltage from pin 18 is
rectified by 6318 and is applied to the Shunt Regulator 7305.
Shunt Regulator 7305 is turned "on", keeping the Power Fail
and Protect lines Low. When AC is removed while the set is
"on", 7305 will turn "off" fast. This is because the filter capacitor
for the input to 7305 is small. When 7305 turns "off", the Power
Fail line goes "high" from the voltage on the +22 Volt line. The
microprocessor will shut the set down while it still has voltage
to operate.

doubler circuit on the SSB, called the Feature Box, changes the
interlaced 625 or 525 signal to a Progressive Scan 480p, 576p,
100Hz, or 120 Hz signal. This YUV signal is buffered and fed to
the SSM where it is buffered before being fed to the HOP (High
end Output Processor) panel. The HOP panel has the HD input
jacks and DB15 RGB input. These inputs can be either 480p,
576p, or 1080i. The Video processing circuits on this panel
perform the Colour, Tint, Brightness, and Contrast adjustments
for the video. Signal selections between the signal from the
SSB and the HD inputs are performed on the HOP panel. Sync
processing and selection is also performed on the HOP panel.
Red, Green, and Blue drive from the HOP panel is fed to the
three CRT panels.
There are two sets of connectors, labelled YPbPr. The one on
the SSM is for NTSC signal levels only. The one on the HOP is
for 1080i, 576p, or 480p Progressive Scan only.
1fH Horizontal (Line) and Vertical (Frame) drive from the SSB
is fed to the HOP via the SSM. The HOP panel selects between
the sync from the SSB or the external HD inputs. These signals
are processed on the HOP before being sent to the LSB.

The composite inputs are located on the SSM. There are two
composite or SVHS inputs. A connector in the SVHS inputs will
mute the composite inputs when the cable in plugged into the
SVHS input. A connector in the SVHS inputs will cause a
voltage change on the SEL-SVHS-RR_STATUS2 line. This will
signal the microprocessor that something is connected to that
input.

When there is a connector in the SVHS input, the composite

Y, and C lines provide 75-ohm impedance matching. If a cable
is plugged into the SVHS connector, the line connecting
resistor, 3029, to ground is removed causing the voltage on the
Y/C_CVBS_SENSE_FRNT line to increase. This signals the
microprocessor to switch the video switching circuits from
composite video to YC In.
There is also a left and right channel audio input.

Selected composite video from the SSM is fed to the HIP 7323,
located on the SSB. IF from the main Tuner, located on the
SSM, is fed to the SSB via connector 1020 to the switchable
SAW filters 1408 and 1410. Refer to Figure "SAW filter
switching circuit" for description of the SAW circuits. IF from the
SAW filters is then fed to Pins 2 and 3 of 7323. composite Video
is output on pin 10 and is buffered by 7411. Video is then fed to
the switchable Sound traps. Refer to Figure "Sound trap
switching circuit" for a description of the Sound Traps. Output
from the Sound traps is buffered by 7322 and fed to pin 14 of
7323. IC 7323 then selects between the Tuner Video and
selected composite Video or Luminance from the SSM on pin
20. If the signal selected is composite video, it is output on pin
26 and buffered by 7320. It is then fed to the Three Line Comb
filter, 7307. Luminance is output on pin 14 and fed back to 7323
on pin 28. Chroma is output on pin 16 and fed to pin 29. The
internal Chroma switch selects between the output of the Comb
filter or external Chroma on pin 21. Selected Chroma is fed to
the internal Demodulator, which outputs UV to the YUV switch.
Selected Luminance is fed to the internal Delay and to the YUV
switch.
The YUV switch selects between the YUV from the internal
decoder and YUV from the YPbPr inputs located on the SSM.
The microprocessor, located on the SSB, via the I2C buss,
SDA-F and SCL-F, controls the HIP 7323. The YPbPr signals
for NTSC are fed through buffer amplifiers on the SSM before
being fed to the SSB. The selected YUV signal is output on
Pins 49, 50, and 51 to the PIP/DW circuit via connector 1682.
The Y or Luminance signal is fed to the internal Sync Separator
to develop Line and Frame sync. This sync is output on pin 60
and 61. pin 60 is the Line sync while pin 61 is the Frame sync.
Line sync is also output on pin 59 to synchronize the Three Line
Comb filter. When the Component input is selected by the YUV
switch (a DVD player for example), the Y signal is selected by
7017 on the SSM and fed to pin 20 of 7323. The selected Y
signal is then fed to the internal Sync Separator.

9.3.5SAW Filter Switching
Figure 9-12 SAW filter switching circuit
The HDR2K3 AP set has a Multi-System tuning system. Since
NTSC uses a 6 MHz bandwidth and PAL/SECAM uses an 8
MHz bandwidth, it is necessary to have separate SAW filters.
The LMN line switches between PAL/SECAM and NTSC.
The LMN line goes "high" in the NTSC mode. Transistor 7405
turns "on" causing a short at the junction of resistor 3406 and
capacitor 2406, removing the signal to the PAL/SECAM SAW
filter (item 1408-A). Transistor 7401 is turned "off". Diode 6402
is forward biased via resistors 3410 and 3406, causing signal
to be applied to pin 2 of 1410-A, and the NTSC SAW filter.
The LMN line goes "low" in the PAL/SECAM mode. Transistor
7405 turns "off", allowing signal to be applied to pin 2 of 1408A, the PAL/SECAM SAW filter. Transistor 7401 is biased "on"
via resistors 3409 and 3407. This prevents the signal from
reaching pin 2 of 1410-A.
9.3.63D Comb Filter
Figure 9-13 3D Comb filter circuit
The 3D Comb Filter is used in NTSC only sets. This is a
separate PC board, which plugs into the System board. The
video signal is buffered by 7008 and 7009. Transistors 7010,
7015, 7016, and 7017 separate the Sync from the composite
video. The Sync is fed to pin 76 of 7023. The composite video
is buffered by 7011 and fed to a 6 MHz filter, 5006. This
prevents any high frequency signals from causing any
problems with the A/D conversion. The signal from 5006 is
buffered by 7012 and fed to pin 88 of 7023. A full frame 3D YC
separation is performed by the YCS circuit. The Y and C
signals are buffered and fed to 6 MHz filters, 5003 and 5004.
The YC signals are then fed back to the SSB via the SSM.

transistor 7407 "on", causing the signal to bypass 1407, the 4.5
MHz filter. The video is then buffered by transistor 7322 before

Circuit Descriptions, List of Abbreviations, and IC Data Sheets
The circuit located on the SSB labelled the Feature Box
performs the digitising, line doubling, and picture resizing. The
main functions are performed by 7611, PICNIC (PICture
improvement Network IC), and 7718, FALCONIC (Field And
Line Converter and Noise reduction IC). The PICNIC IC
performs the A/D Analogue-to-Digital conversion while the
FALCONIC performs the Line Doubling. The FALCONIC also
performs the Super Zoom, Panoramic, 4:3, Movie Expand
14:9, Movie Expand 16:9, 16:9 Subtitle, and Widescreen
picture format conversions.
The YUV signal is fed to the PICNIC on Pins 23, 25, and 26.
Horizontal and Vertical Sync is fed to the IC on Pins 28 and 29.
The signals are fed to a Clamping circuit to limit the sampling
range, an AGC, and a Prefilter circuit. It is then fed to a triple A/
D converter, Time Base Corrector, Noise Reduction and
Histogram circuit, and a Multiplexer. The Prefilter circuit limits
the bandwidth of the signals to prevent aliasing. Aliasing shows
up as artefacts in the picture, which is caused by under
sampling. The Multiplexer combines the three data streams.
Data is output from the PICNIC to FM1 (Field Memory), IC
7714. The Fields are ready by 7718 to the Dynamic Noise
Reduction circuit and to the processor. The De-Interlace writes
the Field data to Field Memory 2, 7717 and Field Memory 2,
7719. The Processor then reads the Field memories to convert
the signal to a progressive scan signal. A Motion Estimator
processes moving blocks in the picture to produce a natural
motion. The processors resize the picture to fit the format
selected by the user. However the picture appears to be
formatted, the output is always a 480P or 576P format. The
Signal is output on two 16-bit busses, F and G, to the Eagle
processor.
The FALCONIC is controlled by the microprocessor in the
PICNIC. The PICNIC is controlled by the Fast clock and data
line from the OTC. The PICNIC communicates with the
FALCONIC and the Eagle via the SN clock and data line. This
is called a SNERT interface. SNERT is a No parity Eight-bit
Reception and Transmission interface.
Horizontal and Vertical sync is output on Pins 18 and 19.

available. The signal is converted to an analogue format and
output on Pins 54, 63, and 73. Sync is output on Pins 28 and
29. The signal is then fed to a buffer circuit on the SSM and
then to the HOP. The Eagle is controlled by the microprocessor
in the PICNIC IC via the SNERT interface. The Eagle outputs
an analogue YUV signal to the SSM (Small Signal Module).

Vertical and Horizontal Peaking circuit sharpens the edges and
adds blue pixels to enhance the picture. This circuit is part of
the Pixel Plus processing.
The Scaling circuit scales the picture to a 100 Hz Digital Scan,
75 Hz Digital Scan, 576 progressive, or 480p progressive. If the
input signal is from an NTSC source, only 75 Hz or 480p is

The input to the HOP panel can be RGB or YPbPr via the cinch
connectors or the Sub-D connector. This connector is not
present in the Basic or Basic Plus versions. The RGB or YPbPr
signal can be either 480P progressive scan or 1080i interlaced.
IC 7110 selects between the R/Pr-G/Y-B/Pb and the RGB
signal from the Sub-D connector. The output of 7110 is fed to
7210, which selects between the output of 7110 and the YUV
signal from the SSM.

The Y/G, B/Pb, and R/Pr signals are fed to their respective
sharpness controls. If the input is a YUV signal, the Y signal is
fed to pin 28 of 7600. The U and V signals are fed to the Tint
Control circuit and then to Pins 27 and 26 of 7600. If the input
is RGB, the signals are fed to Pins 31, 32, and 30 of 7600 to an
RGB to YUV converter. When RGB input is used, there is no
Tint control available for the signal.
The input selector switch in 7600 selects between the YUV on
Pins 28, 27, and 26 or the output of the internal RGB/YUV
converter. The signal is fed to the RGB insertion circuits where
the OSD is inserted. The signal is then fed to a White Point
circuit and then to the Output Amplifier. The White Point and
Output Amplifier have the Drive controls and Cut-off controls.
Input from the ABL line on Pins 43 makes adjustments in the
brightness levels to adjust for changes in beam current. The
AKB pulses from the CRTs are fed to pin 44 to the Cathode
Calibration circuit. The Cathode Calibration circuit adjusts the
Cut-off levels of the CRTs to maintain the correct grey scale
tracking. When the set is first turned "on", a calibration pulse is
output on the RGB lines. The Cathode Calibration circuit
monitors this pulse on the AKB line to set the Black level and
the maximum drive voltage for the cathode. Once the
Calibration has taken place, the Output Amplifiers switches to
the RGB drive signal as the output.
Horizontal and Vertical Sync is fed to 7600 on Pins 23 and 24.
IC 7600 processes the sync to provide the geometry for the
picture. Horizontal drive is output to the sweep circuit on pin 8.
Vertical drive is output on Pins 1 and 2. East West drive is
output on pin 3. Sandcastle (SCO) is output on pin 9. Horizontal
Feedback (HFB) from the sweep circuit is fed into the Phase
Loop to phase correct the Horizontal drive.
IC 7600 is controlled by the microprocessor via the I2C buss on
Pins 10 and 11. Geometry and Drive settings are stored in the
Memory IC located on the HOP panel.

9.3.14 HOP Sharpness Control
Figure 9-21 HOP sharpness control
The Sharpness controls for the YUV/RGB signals are located
on the HOP panel. Since all three circuits are basically the
same, only the Blue one will be discussed.
The Blue signal is fed to pin 1 of 7410. It is also fed to a Low
Pass filter consisting of 5411 and 5410. This path is amplified
by transistor 7411. The Low Pass filter blocks the higher
frequencies as well as shifting the phase of the signal. The
output of the Low Pass filter is also fed to pin 4 of 7410. The
mixing of these two-phase shifted signals only allows the High
frequency component to be amplified and output on pin 12. The
gain of the High frequency component is controlled by the
Sharpness voltage, which is applied to Pins 8 and 10. The two
signals are combined at pin 12 of the IC. If the input was a Blue

Green and Red CRTs, the inverting input on pin 2 will become
greater than the non-inverting input on pin 3, resulting in the
output on pin 1 to go Low. The ABL line will go Low, causing
7600 to reduce the drive to all of the CRTs. This circuit prevents
the Blue tube from being over-driven.

The output of 7600 is fed to the RGB amplifiers before being
fed to the CRTs. Transistors 7720 and 7721 buffer the Blue
output on pin 42. The B-BIAS control voltage controls the gain
of this circuit. Transistor 7730 provides an additional voltage
gain for the signal.
Items 7710 and 7711 buffer the Green output from pin 41 of
7600. The G-BIAS controls the gain of the circuit.
The Red output from pin 40 of 7600 is buffered by 7700 and
7701. The R-BIAS controls the gain of the circuit.
The drive of the Red and Green outputs is compared with the
Blue drive by 7900-A. The difference signal is fed back to 7600

Sync from the SSB. For separate Horizontal and Vertical Sync,
the output of 7210 is fed to the multiplexer IC 7330, which is
used as a switch. In the case of Sync on Y or Sync on Green,
pin 19 of 7210 is fed to pin 18 of 7210 to a Sync Separator. If
separate Horizontal Sync is present, the internal detector in
9.3.20 Line Output
7210 turns the Sync Separator "off". The Sync output on pin 17
is fed to a Low Pass Filter, which separates the Vertical Sync.
The Timer IC 7328 detects the Horizontal Sync and feeds it to
7330. The detected Horizontal Sync from 7328 is fed to pin 1 of
7330 to switch the IC to the pin 6 and 3 inputs.
Horizontal drive from the HOP panel is fed to 7807 on the Large
Signal panel. Transistor 7807 drives the Horizontal Output
Transistor 7801, which drives the Yokes and the Horizontal
Output Transformer 5801. Transformer 5801 produces plus
and minus 13-Volt supplies for the Vertical Output circuit. It also
produces a 200-Volt source and Filament voltage for the CRT
panels. The output of 7807 also drives 7803 and 7802, which
drives the Dynamic Focus circuit.

The High Voltage module is an integrated High Voltage supply
with its own switching power supply. When the set is turned
"on", 11.5 volts from the Sweep Failure detection circuit is fed
to diode 6913 and to pin 8 of the High Voltage module. A supply
voltage of 130 volts is also fed to pin 10 of the module. The
Module then outputs High voltage to the three CRTs. It also
outputs Focus voltage to the Focus G2 block. Output on pin 4
is rectified by 6917 to produce a negative 200 Volt source for
the CRT G1 voltage. The voltage is also rectified by 6919 to

DAG line along with the output on pin 2 is connected to 7903 to
produce the ABL voltage for the set. If an over-current condition
should develop with the drive, the ABL voltage will go Low,
turning 7905 "on", latching 7904, which will remove drive to pin
8 of the HVG. This will cause the High voltage to shut "off".
Vertical Parabola drive is fed to 7901 to produce the Vertical
component of the Dynamic Focus drive.
Figure 9-30 Blanking and HV-protection circuit
The Shutdown circuit will shut the High voltage "off" if the
Horizontal or Vertical Sweep should fail. It will also shut the
High voltage "off" if the Power Fail line goes "high" or the +200
Volt source should fail.

keeps capacitor 2837 charged. This pulse is rectified by 6815
to keep the base of 7808 at a negative voltage. This keeps the

transistor turned "off". In the same manner, the Negative
Horizontal pulses keep the base of 7810 at a negative voltage
to keep it turned "off". The Protect line is normally Low, keeping
7809 turned "off". The +200-volt source is fed through zener
diodes 6812 and 6816, resistor 3850, the base-emitter of 7906,
the base emitter of 7812 to keep transistor 7813 turned "on".
This turns transistor 7814 "on", which switches the "on" voltage
to the High Voltage module. The conduction of 7812 keeps the
voltage on the G1 line at approximately - 18 Volts, which turns
the CRTs "on". If the Vertical Pulse should fail, transistor 7808
will turn "on", which will turn 7906, 7812, 7813, and 7814 "off".
This will turn the HVG module "off". In addition when 7812 turns
"off", the G1 voltage will go to -200 Volts, blanking the CRTs.
The same sequence will occur if Horizontal should fail, the
Protect line should go "high", or the +200 Volt source should
fail.
9.3.24 Convergence
The Convergence system is split into two sections. The
convergence signal processor is located on the ACS (Auto
Convergence System) module. The output amplifiers are
located on the SSM (Small Signal Module).
Convergence Processor
Intellisense Sensing Circuit
The Basic version of the HDRPTV does not have the Sensors
installed in the set. However, the Sensor Test is in the Service
Convergence menu. When the Convergence alignments are
stored, the microprocessor will attempt to read the Sensors. If
the Sensor test is selected in the Convergence Alignment
menu, the message will read “Sensors not verified at locations:
1234.” This will not affect the Convergence alignments.
Convergence Horizontal Output
E_15000_103.eps
181004
Figure 9-32 Convergence horizontal output circuit
E_15000_099.eps
Figure 9-31 Convergence signal processor
The Convergence data is stored in the EEPROM, 7000. The
microprocessor located on the ASC module reads 1,971 bytes
of data from 7000 and writes it to the Convergence Processor,
7002. Horizontal sync is inverted by 7026, buffered by 7025,
and fed to pin 27 of 7002. Vertical sync is inverted by 7027,
buffered by 7028, and fed to pin 28 of 7002. The data is
processed to produce the desired convergence correction
waveforms, which are output on six DACS. During the
convergence adjustment procedure, a 180-point alignment grid
is output on Pins 16, 17, and 18. This signal is mixed with the
OSD to be displayed on the screen. In the 4x3 aspect ratio set,
there are three sets of convergence data. In sets with a 16x9
aspect ratio, there are two sets of convergence data. The set
will require convergence alignment for each set of convergence
data. The correct mode must be selected and the signal for that
mode must be applied to the set during the convergence
alignment. The output of the DACS is fed to six op-amps before
being fed to the Power Amplifiers located on the SSM. When
screen centring is being performed, it is necessary to disable
the convergence drive waveform. A High on pin 77 turns
transistor 7029 "on", turning 7038 "on", which turns transistors
7032, 7033, 7030, 7031, 7034, and 7035 "on". This mutes the
correction drive signal to the Power Amplifiers.
181004
IC 7044 amplifies the Horizontal convergence waveforms. The
correction waveforms are fed to the IC on Pins 6, 14, and 15.
They are output to the Convergence Yokes on Pins 9, 11, and
18. The IC is powered by four supply inputs. A +35 Volt supply
is fed to pin 5, a -35 Volt supply is fed to pin 4, and a -22 Volt
supply is fed to pin 8, 12, and 17. The supply fed to pin 10 is
normally a +22 Volt supply. During signal peak drives, the
voltage on pin 10 is increased to +35 Volts. Feedback sense
voltage is developed across the 6.8 ohm resistors on the return
side of each yoke. Transistor 7007 is part of a Soft Start circuit.
When the set is turned "on", Transistor 7007 turns "on" until
capacitor 2043 is fully charged. While 7007 is being turned
"on", a negative voltage is placed on pin 3 muting the output of
the IC. A 220-ohm snubber resistor is across each of the yoke
windings. This resistor will overheat if the unit is operated with
the Convergence Yokes unplugged.

resistor is across each yoke. These resistors will overheat if the
circuit is operated without the Convergence Yokes being
plugged in. The IC is powered by four supplies, +35 Volt, -35
Volt, VccPSW-V, and VCCNSW-V. The VccPSW-V supply is
normally at +22 volts. The BV_OUT, GV_OUT, and RV_OUT
lines are connected to a Vertical Power up circuit, which
senses the drive to the Convergence Yokes. If the drive to the
yokes reaches 10 to 12 Volts, the Vertical Power up circuit will
switch the VccPSW-V supply to +35 Volts. If the Vertical Power
up circuit senses a negative 10 to 12 volt drive to the Vertical
Convergence yokes, the VccNSW-V supply will switch from 22 Volts to -35 Volts. As with the Horizontal drive circuit, 7005
mutes the output of 7045 during power up.

processing includes Volume, Equalizer, balance, Loudness,
Incredible Sound, and Virtual Dolby. After processing, the
Audio signal is fed to six D/A converters. The Main Speaker

The Audio Amplifier is located on the SSM. The output power
for the Audio Amplifier is 10 Watts per channel for the Basic
and Basic Plus versions. The Core Version has an output of 15
Watts per channel. IC 7700 is the Audio output IC. This is a
class D amplifier. Left and Right Audio from the SSB is fed to
Pins 10 and 18 of the IC. The output stages are basically switch
mode circuits, driven by the audio input signal. The frequency
of the output is keep at 200 kHz by an internal 200 kHz
oscillator. The pulse width of the output is determined by the
signal level of the input signal. The Right Channel pulse width
signal is output on pin 3. The output is filtered by 5701, 2777,
2776, 2717, 5716, and 2737. The amplified audio is output on
connection 1349. In the same manner, Left audio is output on
pin 23. The IC is powered by +19 and -19 Volt supplies. The
supplies are protected by fuses 1700 and 1701. The Supply
voltage for the Core version is 4 volts higher than the Basic and
Basic plus version. The extra supply voltage is needed to
produce the additional 5 Watts per channel output.
Muting and volume control for the audio takes place in the
Audio Signal processor on the SSB. The STBY MUTE line on
pin 6 goes to 2.5 Volts to mute the audio when the set is turned
"on" or "off". This line goes "low" to place the amplifier in a
Standby mode if a DC voltage is detected on the Audio Output
lines.

The Core versions have a Centre Channel amp switch, located
on the rear of the set. The Output of the Audio Amplifier on the
Basic and Basic Plus versions are fed directly to the speakers.
In the Core sets, the Output is fed to the Centre Channel amp
switch before being fed to the speakers. When the Centre
Channel amp switch is placed in the External position, the Left

external speaker input. In cases where the Customer has a
separate sound system, this switch allows the speakers in the
set to be used as the centre output.

The Audio Amplifier will be placed in a Standby mode and the
set will shut down if a DC voltage is detected on the Speaker
Output lines. The Left and Right audio output lines are
connected to the base of 7704 and the emitter of 7705 via
resistors 3718 and 3717. Filter capacitor 2778 filters out the AC
component of the waveform. If the DC voltage goes positive,
7704 will turn "on". If the voltage goes negative, 7705 will turn
"on". This turns 7706 "on" which turns 7707 "on". This causes
the Front Detect line to go Low, preventing the microprocessor
from receiving any commands. It also turns SCR 6701 "on",
turning transistor 7708 "on", causing the Standby line to go
"high". If this SCR is turned "on", it will be necessary to remove
power from the set to reset the circuit. This will turn the set "off".
Transistor 7707 also turns "on", causing the Standby-Mute line
to go Low. This places the Audio Output IC in a Standby mode.
If the Power Fail line should go "high", 7710 will turn "on",
causing the Standby-Mute line to go Low.

turned "on", the processor monitors the Keyboard and IR
receiver located on the Sensor Board. This IC controls the
functions on the SSB, Video switching on the SSM, and the
PIP/DW panel. A ROM located inside the IC has the Startup
program. The main program to run the processors is located in
the Program Flash RAM, 7006. IC 7012 is used by the OTC for
temporary storage. IC 7007 is used to store data for Teletext.
There are three I2C busses, a fast bus, F, a slow bus, S, and a
TX bus to communicate with the microprocessor on the ACS
module. The NVM 7011 stores settings such as customer
preferences, OPT numbers, Tuner settings, and Error codes.
composite video is fed to pin 5 for decoding Teletext and
Closed Caption information. In the Standby mode, Power is not
applied to the processor on the ACS module.
The microprocessor, 7100, located on the ACS module,
controls the Convergence, Geometry, and CRT drive circuits.
Settings for Convergence, Geometry, and White drive are
stored in the NVM, 7000. This IC is 512K for the AP sets and
256K for the Korean version. When 7100 reads the size of
7000, it then determines which software to load. If it reads 512K
present, the AP software is loaded. If it reads 256K, NTSC only
software is loaded. Commands for the ACS processor are
produced by the OTC on the SSB and transmitted via the TXD

Figure 9-41 Front Control Panel
The Front Control panel has the Power LED, Keyboard, IR
Receiver, and Light Sensor. The Keyboard is a resistor ladder.
The voltage changes value depending on which selection is
made. The voltage on this line will be 3.3 volts if no buttons are
selected. The two-colour LED indicates the status of the set. In
the Standby mode, the ON_OFF_LED line is High and the +9volt source is turned "off". In this case, the RED LED is lit.
When the set is turned "on", the +9-volt source is switched "on",
turning the Green section of the LED "on". The LED then turns
Yellow. When the set is fully "on", the ON_OFF_LED line goes
Low, turning the Red LED "off". The indicator is now Green.
The IR Receiver, 6105, receives commands from the remote
control.

Figure 9-43 I2C interconnect
The OTC communicates with the set via three I2C busses.
SDA-F, Fast bus communicates with the PICNIC, HIP, and
MSP (Audio Processor). The SN-DA line from the PICNIC
communicates with the FALCONIC and EAGLE. The SDA-S
Slow bus communicates with the Tuner, AV Switch, and
ComPair connector on the SSM. It also communicates with the
PIP-DW board.
The TXD and RXD lines communicate with the microprocessor
on the ACS module. The microprocessor on the ACS
communicates with the GDE NVM, Convergence Processor,
and the HOP panel.

9.5.5On-Screen Display
Figure 9-44 On-Screen Display
Signal for the OSD (On-Screen Display) comes from three
different sources. IC 7001, which is located on the SSB (Small
Signal Board), generates all of the customer menus except for
Convergence.
In the SAM (Service Alignment Mode), the menus are
generated by 7001, except those in the GDE SAM. The GDE
SAM menus are generated by IC 7100 on the ACS module.
The Convergence Alignment menus are generated by 7100,
while the Convergence Alignment grid is generated by IC 7002.
The OSD signals from 7001 on the SSB are fed to the SSM
(Small Signal Module) via connector 1002 and 1043. The OSD
signals from the Convergence Processor, 7002, are buffered
by 7014 through 7017 before being mixed with the signals from
the ACS microprocessor, 7100. They are fed to the SSM via
connector 1000. The signals from the ACS and SSB are mixed
and fed to the HOP panel and HOP IC, 7600, via connector
1610. The HOP IC, 7600, mixes the OSD signal with the video
signal before feeding it to the CRTs.
