EN 5L06.1E2.
Index of this chapter:
2.1 Safety Instructions
2.2 Maintenance Instructions
2.3 Warnings
2.4 Notes
2.1Safety Instructions
Safety regulations require the following during a repair:
•Connect the set to the Mains/AC Power via an isolation
transformer (> 800 VA).
•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, the set must be
returned 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 flows. 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.
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/AC Power lead for
external damage.
•Check the strain relief of the Mains/AC Power 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/AC
Power plug and the secondary side (only for sets that have
a Mains/AC Power isolated power supply):
1. Unplug the Mains/AC Power cord and connect a wire
between the two pins of the Mains/AC Power plug.
2. Set the Mains/AC Power switch to the "on" position
(keep the Mains/AC Power cord unplugged!).
3. Measure the resistance value between the pins of the
Mains/AC Power plug and the metal shielding of the
tuner or the aerial connection on the set. The reading
should be between 4.5 Mohm and 12 Mohm.
4. Switch "off" the set, and remove the wire between the
two pins of the Mains/AC Power plug.
•Check the cabinet for defects, to prevent touching of any
inner parts by the customer.
2.2Maintenance Instructions
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.
•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 figure “Discharge
picture tube”, to discharge the picture tube. Use a high
voltage probe and a multi-meter (position V
until the meter reading is 0 V (after approx. 30 s).
V
Figure 2-1 Discharge picture tube
•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 same potential. Available
ESD protection equipment:
– Complete kit ESD3 (small tablemat, wristband,
connection box, extension cable and earth cable) 4822
310 10671.
– Wristband tester 4822 344 13999.
•Be careful during measurements in the high voltage
section.
•Never replace modules or other components while the unit
is switched "on".
•When you align the set, use plastic rather than metal tools.
This will prevent any short circuits and prevents circuits
from becoming unstable.
2.4Notes
2.4.1General
•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 for PAL, or
61.25 MHz for NTSC (channel 3).
•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 stand-by (F). These values are
indicated by means of the appropriate symbols.
•The semiconductors indicated in the circuit diagram and in
the parts lists, are interchangeable per position with the

2.4.2Schematic Notes
•All resistor values are in ohms, and the value multiplier is
often used to indicate the decimal point location (e.g. 2K2
indicates 2.2 kohm).
•Resistor values with no multiplier may be indicated with
either an "E" or an "R" (e.g. 220E or 220R indicates 220
ohm).
•All capacitor values are given in micro-farads (µ= x10

•Capacitor values may also use the value multiplier as the
decimal point indication (e.g. 2p2 indicates 2.2 pF).
•An "asterisk" (*) indicates component usage varies. Refer
to the diversity tables for the correct values.
•The correct component values are listed in the Spare Parts
List. Therefore, always check this list when there is any
doubt.
2.4.3Rework on BGA (Ball Grid Array) ICs
General
Although (LF)BGA assembly yields are very high, there may
still be a requirement for component rework. By rework, we
mean the process of removing the component from the PWB
and replacing it with a new component. If an (LF)BGA is
removed from a PWB, the solder balls of the component are
deformed drastically so the removed (LF)BGA has to be
discarded.

Device Removal
As is the case with any component that is being removed, it is
essential when removing an (LF)BGA, that the board, tracks,
solder lands, or surrounding components are not damaged. To
remove an (LF)BGA, the board must be uniformly heated to a
temperature close to the reflow soldering temperature. A
uniform temperature reduces the risk of warping the PWB.
To do this, we recommend that the board is heated until it is
certain that all the joints are molten. Then carefully pull the
component off the board with a vacuum nozzle. For the
appropriate temperature profiles, see the IC data sheet.
Area Preparation
When the component has been removed, the vacant IC area
must be cleaned before replacing the (LF)BGA.
Removing an IC often leaves varying amounts of solder on the
mounting lands. This excessive solder can be removed with
either a solder sucker or solder wick. The remaining flux can be
removed with a brush and cleaning agent.
After the board is properly cleaned and inspected, apply flux on
the solder lands and on the connection balls of the (LF)BGA.
Note: Do not apply solder paste, as this has been shown to
result in problems during re-soldering.
Device Replacement
The last step in the repair process is to solder the new
component on the board. Ideally, the (LF)BGA should be
aligned under a microscope or magnifying glass. If this is not
possible, try to align the (LF)BGA with any board markers.
So as not to damage neighbouring components, it may be
necessary to reduce some temperatures and times.
More Information
For more information on how to handle BGA devices, visit this
URL: www.atyourservice.ce.philips.com (needs subscription,
not available for all regions). After login, select “Magazine”,
then go to “Repair downloads”. Here you will find Information
on how to deal with BGA-ICs.
Due to lead-free technology some rules have to be respected
by the workshop during a repair:
•Use only lead-free soldering tin Philips SAC305 with order
code 0622 149 00106. If lead-free solder paste is required,
please contact the manufacturer of your soldering
equipment. In general, use of solder paste within
workshops should be avoided because paste is not easy to
store and to handle.
•Use only adequate solder tools applicable for lead-free
soldering tin. The solder tool must be able:
– To reach a solder-tip temperature of at least 400°C.
– To stabilise the adjusted temperature at the solder-tip.
– To exchange solder-tips for different applications.
•Adjust your solder tool so that a temperature of around
360°C - 380°C is reached and stabilised at the solder joint.
Heating time of the solder-joint should not exceed ~ 4 sec.
Avoid temperatures above 400°C, otherwise wear-out of
tips will increase drastically and flux-fluid will be destroyed.
To avoid wear-out of tips, switch “off” unused equipment or
reduce heat.
•Mix of lead-free soldering tin/parts with leaded soldering
tin/parts is possible but PHILIPS recommends strongly to avoid mixed regimes. If this cannot be avoided, carefully
clean the solder-joint from old tin and re-solder with new
tin.
•Use only original spare-parts listed in the Service-Manuals.
Not listed standard material (commodities) has to be
purchased at external companies.
•Special information for lead-free BGA ICs: these ICs will be
delivered in so-called "dry-packaging" to protect the IC
against moisture. This packaging may only be opened
shortly before it is used (soldered). Otherwise the body of
the IC gets "wet" inside and during the heating time the
structure of the IC will be destroyed due to high (steam-)
pressure inside the body. If the packaging was opened
before usage, the IC has to be heated up for some hours
(around 90°C) for drying (think of ESD-protection!).
Do not re-use BGAs at all!
Page 7
Safety Instructions, Warnings, and Notes
•For sets produced before 1.1.2005, containing leaded
soldering tin and components, all needed spare parts will
be available till the end of the service period. For the repair
of such sets nothing changes.
In case of doubt whether the board is lead-free or not (or with
mixed technologies), you can use the following method:
•Always use the highest temperature to solder, when using
SAC305 (see also instructions below).
•De-solder thoroughly (clean solder joints to avoid mix of
two alloys).
Caution: For BGA-ICs, you must use the correct temperatureprofile, which is coupled to the 12NC. For an overview of these
profiles, visit the website www.atyourservice.ce.philips.com
(needs subscription, but is not available for all regions)
You will find this and more technical information within the
"Magazine", chapter "Repair downloads".
For additional questions please contact your local repair help
desk.
2.4.5Alternative BOM identification
In September 2003, Philips CE introduced a change in the way
the serial number (or production number, see Figure 2-2) is
composed. From this date on, the third digit in the serial
number (example: AG2B0335000001) indicates the number of
the alternative BOM (Bill of Materials used for producing the
specific model of TV set). It is possible that the same TV model
on the market is produced with e.g. two different types of
displays, coming from two different O.E.M.s.
By looking at the third digit of the serial number, the service
technician can see if there is more than one type of B.O.M.
used in the production of the TV set he is working with. He can
then consult the At Your Service Web site, where he can type
in the Commercial Type Version Number of the TV set (e.g.
29PT9521/12), after which a screen will appear that gives
information about the number of alternative B.O.M.s used.
If the third digit of the serial number contains the number 1
(example: AG1B033500001), then there is only one B.O.M.
version of the TV set on the market. If the third digit is a 2
(example: AG2B0335000001), then there are two different
B.O.M.s. Information about this is important for ordering
the correct spare parts!
For the third digit, the numbers 1...9 and the characters A...Z
can be used, so in total: 9 plus 26 = 35 different B.O.M.s can
be indicated by the third digit of the serial number.
EN 7L06.1E2.
2.4.6Practical Service Precautions
•It makes sense to avoid exposure to electrical shock.
While some sources are expected to have a possible
dangerous impact, others of quite high potential are of
limited current and are sometimes held in less regard.
•Always respect voltages. While some may not be
dangerous in themselves, they can cause unexpected
reactions that are best avoided. Before reaching into a
powered TV set, it is best to test the high voltage insulation.
It is easy to do, and is a good service precaution.

the set. You only have to connect the IAP interface circuit to the
service connector (on the rear of the set, and start the software
uploading (see also chapter 5 "Service Modes, Error Codes,
and Fault Finding").
4.2Set Disassembly
Follow the disassemble instructions in described order.
4.2.1Rear Cover Removal
Warning: disconnect the mains power cord before you remove
the rear cover.
1. Remove all the fixation screws of the rear cover.
2. Now the rear cover can be removed.
4.3Service Positions
Only the LSP of this chassis has a service position for better
access to the component side of the LSP. For the SSB, there
is no specific service position.
4.3.1Large Signal Panel (LSP)
Component Side LSP
For better accessibility of the LSP, do the following (see
Figures “Service position LSP” and “Locking handles LSP”):
1. Simultanuously do the following: a) pull the two plastic
locking handles at the mid left and mid right side of the
bracket gently backwards to unlock the bracket, and b)
loosen the bracket from the bottom tray, by pulling it
backwards. N.B.: You do not need to pull the other two
locking handles backwards.
2. Remove the LSP-bracket from the bottom tray by lifting it
upwards.
3. Hook the bracket in the first row of fixation holes of the
bottom tray. In other words, reposition the bracket from [1]
to [2].
Figure 4-1 Service position LSP

Figure 4-2 Locking handles LSP
Solder Side LSP
To get access to the bottom side (solder side) of the LSP, do
the following:
1. Remove all the connectors from the LSP.
2. Remove the LSP, still in its plastic bracket, from the
chassis, so the bottom side of the LSP can be reached. If
necessary, remove the LSP also from its plastic bracket.
4.3.2Small Signal Board (SSB)
There is no service position for the SSB. Most test points are
located on the component side. If you have to replace ICs, you
must remove the complete SSB module from the TV set (see
further down in this chapter: Small Signal Board, SSB).

4.5Set Re-assembly
To re-assemble the whole set, do all processes in reverse
order.
Be sure that, before the rear cover is mounted:
•The mains cord is postioned correctly in its guiding
brackets (make sure that the strain relief will function
correctly!).
•All wires/cables are returned in their original positions. This
is very important, in view of the “hot” and “EHT” areas of the
set.
•Check if no wires are touching the heat sinks that are on
the LSP; this may dammage the cables!

5.8 Fault Finding and Repair Tips
5.1Test Points
This chassis is equipped with test points in the service printing.
In the schematics, test points are identified with a rectangle box
around Fxxx or Ixxx. These test points are specifically
mentioned in the service manual as “half moons” with a dot in
the centre.
The chassis is equipped with test points (Fxxx) printed on the
circuit board assemblies. As most signals are digital, it will be
almost impossible to measure waveforms with a standard
oscilloscope. Therefore, waveforms are not given in this
manual.
Perform measurements under the following conditions:
•Television set in Service Default Alignment Mode.
•Video input: Colour bar signal.
•Audio input: 3 kHz left channel, 1 kHz right channel.
– Timer / Sleep timer.
– Child / parental lock.
– Blue mute.
– Hotel / hospital mode.
– Auto shut off (when no “IDENT” video signal is
received for 15 minutes).
– Skipping of non-favourite presets / channels.
– Auto-storage of personal presets.
– Auto user menu time-out.
– Auto Volume Levelling (AVL).
How to Enter
To enter SDM, use one of the following methods:
•Press the following key sequence on the remote control
transmitter: “062596” directly followed by the MENU button
(do not allow the OSD display to time out between entries
while keying the sequence).
•Short the SDM contact to mass (see Figure "SDM Service
contact") on the TV board and apply AC Power. Remove
the short after start-up.
Caution: Entering SDM by shorting the "Service" contact
to mass will override the software protections. Do this only
for a short period. When doing this, the service-
technician must know exactly what he is doing, as it
could damage the television set.
5.2Service Modes
Service Default mode (SDM) and Service Alignment Mode
(SAM) offer several features for the service technician, while
the Customer Service Mode (CSM) and the Digital Customer
Service Mode (DCSM, only for TVs with digital reception
module) are used for communication between the call centre
and the customer.
This chassis offers the option of using the IAP Tool (In
Application Programming), a hardware interface between a
computer and the TV chassis, for software uploading to the TV
set. See also paragraph "Service Tools: IAP Tool").
5.2.1Service Default Mode (SDM)
Purpose
•To create a predefined setting for measurements to be
made.
•To override software protections.
•To start the “Blinking LED Procedure”.
•To inspect the error buffer.
•To check the life timer.

5.2.3Customer Service Mode (CSM)
Purpose
The Customer Service Mode shows error codes and
information on the TV’s operation settings. The call centre can
instruct the customer (by telephone) to enter CSM in order to
identify the status of the set. This helps the call centre to
diagnose problems and failures in the TV set before making a
service call.
The CSM is a read-only mode; therefore, modifications are not
possible in this mode.

5.5Error Codes
5.5.1Introduction
The error code buffer contains all detected errors since the last
time the buffer was erased. The buffer is written from left to
right, new errors are logged at the left side, and all other errors
shift one position to the right.
When an error has occurred, the error is added to the list of
errors, provided the list is not full or the error is a protection
error.
When an error occurs and the error buffer is full, then the new
error is not added, and the error buffer stays intact (history is
maintained), except when the error is a protection error.
To prevent that an occasional error stays in the list forever, the
error is removed from the list after 50+ operation hours.
When multiple errors occur (errors occurred within a short time
span), there is a high probability that there is some relation
between them.
5.5.2How to Read the Error Buffer
Use one of the following methods:
•On screen via the SAM (only if you have a picture).
Examples:
– 0 0 0 0: No errors detected
– 6 0 0 0: Error code 6 is the last and only detected error
– 9 6 0 0: Error code 6 was first detected and error code
9 is the last detected error
•Via the blinking LED procedure (when you have no
picture). See next paragraph.
•Via IAP.
5.5.3How to Clear the Error Buffer
Use one of the following methods:
•By activation of the “CLEAR ERRORS” command in the
SAM menu.
•With a normal RC, key in sequence “MUTE” followed by
“062599” and “OK”.
•If the content of the error buffer has not changed for 50+
hours, it resets automatically.
5.5.4Error Codes
The function of error codes is to indicate failures in the TV set.
In principle a unique error code is available for every:
2
•I
C device error.
2
•I
C bus error (for every bus containing two or more I2C
devices).
•Protection error (e.g. +8V protection or Horizontal
protection).
•Error not related to an I
BC-loop, RAM error).
2
C device, but of importance (e.g.
EN 15L06.1E5.
Note: The device depends on the Flash IC used.
•Select File > Load, and select the .bin file to be
programmed to the Flash IC.
•Select File Type “Binary”.
•Select “Write Device”.
Note: If there are no errors reported, the programming is
successful.
Note: Sometimes, an error message may appear. Please
try a few times if this happens.

Service Tips:
•In case of non-intermittent faults, clear the error buffer
before you begin the repair. This to ensure that old error
codes are no longer present. Before clearing the buffer,
write down the content, as this history can give you
significant information.
•If possible, check the entire contents 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).
5.6The Blinking LED Procedure
5.6.2How to Activate
Use one of the following methods:
•Activate the SDM (only by shorting the soldering pad
indicated in Figure “SDM Service contact” on the first page
of this chapter to mass). The blinking front LED will show
the entire contents of the error buffer (this works in “normal
operation” mode and in “protection” mode). In order to
avoid confusion with RC5 signal reception blinking, this
LED blinking procedure is terminated when an RC5
command is received.
•Transmit the commands “MUTE”, “06250x”, and “OK” with
a normal RC (where “x” is the position in the error buffer
that has to be displayed). With x= 1, the last detected error
is shown, x= 2 the second last error, etc.... When x= 0, all
errors are shown.
•“DIAGNOSE X” with the DST (where “x” is the position in
the error buffer that has to be displayed). With x= 1, the last
detected error is shown, x= 2 the second last error, etc....
When x= 0, all errors are shown.
Note: It can take some seconds before the blinking LED starts.
5.7Software Downloading
In this chassis, you can upgrade the software via the IAP Tool
(In Application Programming). You can find more information
on this in the paragraph “Service Tools” in this chapter.
5.8Fault Finding and Repair Tips
Notes:
•It is assumed that the components are mounted correctly
with correct values and no bad solder joints.
•Before any fault finding actions, check if the correct options
are set.
5.8.1NVM Editor
In some cases, it can be handy if one directly can change the
NVM contents. This can be done with the “NVM Editor” in SAM
mode. In the next table, the default NVM values are given.
5.6.1Introduction
Via this procedure, you can make the contents of the error
buffer visible via the front LED. This is especially useful for fault
finding, when there is no picture.
When the SDM is activated, the front LED will show (by
blinking) the contents of the error-buffer. Error-codes > 10 are
shown as follows:
1. A long blink of 750 ms (which is an indication of the decimal
digit),
2. A pause of 1500 ms,
3. “n” short blinks (where “n” = 1 - 9),
4. When all the error-codes are displayed, the sequence
finishes with a LED blink of 3000 ms,
5. The sequence starts again.
Example: Error 12 9 6 0 0.
After activation of the SDM, the front LED will show:
1. 1 long blink of 750 ms (which is an indication of the decimal
digit) followed by a pause of 1500 ms,
2. 2 short blinks of 250 ms, followed by a pause of 3000 ms,
3. 9 short blinks of 250 ms, followed by a pause of 3000 ms,
4. 6 short blinks of 250 ms, followed by a pause of 3000 ms,
5. 1 long blink of 3000 ms to finish the sequence,
•When aligning a TV set, it is convenient to start with the
default settings, and then to change them, if necessary, to
customized values.
•If you suspect a defective TV set is programmed with the
wrong settings or options, try to restore the set to its default
settings or set the options to their virgin mode (the latter
can also be done via the NVM Editor in the SAM menu, see
chapter 8 and the table Option codes).
If the remote control of a TV set is defective of missing, and
you can not enter the CSM or SAM menu, it is always
possible to return the TV to its virgin mode by
simultaneously pressing the Volume+ and Volume- keys
on the Top Control/Side I/O panel of the TV set.

Perform all electrical adjustments under the following
conditions:
•Power supply voltage: 230 V
•Connect the set to the mains via an isolation transformer
with low internal resistance.
•Allow the set to warm up for approximately 20 to 30
minutes.
•Measure voltages and waveforms in relation to chassis
ground (with the exception of the voltages on the primary
side of the power supply).
Caution: never use heatsinks as ground.
•Test probe: 100 : 1, Ri > 10 Mohm, Ci < 3.5 pF.
•Use an isolated trimmer/screwdriver to perform
alignments.
Perform all electrical adjustments with the following default
settings (for all CRTs):
•Choose "Soft" picture mode with the "Smart Picture" button
on the remote control.
•Set "Dynamic Contrast" and "Active Control" to "off" (if
either one of them is present).
•Set "Brightness" to aligned value unless otherwise
specified.
•Set "Contrast value" to 99.
8.1.2Adjustment Sequence
Use the following adjustment sequence:
1. Set the correct TV-set OPTIONS as described in
paragraph "Options". After storing, re-start the set.
2. Rough adjustment of VG2 and FOCUS (potentiometers in
“midway” positions; N.B.: wrong positions may cause error
messages because of H or V-protection mechanism).
3. RF-AGC alignment.
4. Rough adjustment of GEOMETRY.
5. Allow the set to warm up.
6. Precise adjustment of VG2 and FOCUS.
7. Precise adjustment of GEOMETRY.

8.2.1Vg2 Adjustment
In the frame-blanking period of the R, G, and B signals applied
to the CRT, the video processor inserts a measuring pulse with
different DC levels. Measure the black level pulse during the
vertical flyback at the RGB cathodes of the CRT (pin 8 = R, 6 =
G, 11 = B).
1. Connect the RF output of a pattern generator to the
antenna input. Input a "black" picture (blank screen on CRT
without any OSD info) test pattern.
2. In the SAM mode, set the “Normal Red”, “Normal Green”
and “Normal Blue” values to “0” for “White Tone”.
3. Disable the black current loop (via the AKB bit).
4. Use the MENU key to enter the "user" menu, select
"Picture", and set "Brightness" and "Contrast" to “0”.
5. Set the oscilloscope to 20 V/div and the time base to 20 us/
div. Use external triggering on the vertical pulse.
Caution: use a trigger point on the "cold" side!
6. Ground the scope on the CRT panel ("cold" side) and
connect a 10:1 probe to one of the cathodes of the picture
tube socket (see circuit diagram F).
7. Measure at cathodes on the picture tube socket the DClevel of the measuring pulse (1st full line after the frame
blanking) with respect to earth; N.B.: R = pin 8, G = pin 6,
B = pin 11 of CRT socket.
8. Select the pin with the highest level found and adjust
V_cutoff by means of the Vg2-potmeter (lowest-one) on the
Line Output Transformer (LOT) to 145 +/- 5 V
screen sizes).
9. Reset "Contrast" and "Brightness" to their original values.

8.2.2Focus alignment
The LOT has the following outline:
– Focus 1 (F1) = Static alignment (red wire).
– Focus 2 (F2) = Dynamic alignment (white wire).
1. Use an external video pattern generator to input a "circle"
or "crosshatch" test pattern to the set.
2. Choose "Natural" picture mode with the "Smart Picture"
button on the remote control transmitter.
3. Adjust the "dynamic focus 2" potentiometer (in the middle
on the LOT) until the horizontal lines at the centre of the
screen are of minimum width without introducing a visible
haze.
4. Adjust the "static focus 1" potentiometer (highest of the
LOT) until the horizontal lines at the sides of the screen are
of minimum width without introducing a visible haze.
5. Repeat these two steps to achieve the best result.
8.3Software Alignments
Put the set in the SAM (see the "Service Modes, Error Codes
and Fault Finding" section). The SAM menu will now appear on
the screen. The different alignment parameters are described
further on.
Notes:
•All changes to menu items and alignments must be stored
manually.
•If an empty EAROM (permanent memory) is detected, all
settings are set to pre-programmed default values, so the
set must be re-aligned.
Service tip: When the set is equipped with a rotation coil, use
this menu item to check its correct alignment. If alignment is not
correct, go to the user MENU, choose FEATURES, and select
ROTATION. With the use of a crosshatch test pattern, align it
to a correct horizontal picture.

Figure 8-3 Geometry Alignments
Select “Pixel Plus” mode and put a test picture on the screen.
Use the following software regulations to modify the vertical
parts of the screen geometry (see Figure “Geometry
Alignments” for a general idea of what you should see on the
screen):
1. VSH (Vertical Shift): Align for the vertical picture centre,
range from 0 to +63.
2. VAM (Vertical Amplitude): Compensating for any gain error
in amplifier, adjust range from 0 to +63 to the proper
amplitude.
3. VSC (Vertical S-Correction): Align for equal height of the
blocks in the top, the bottom and the middle, range from 0
to +63.
4. VS (Vertical Slope). First activate menu item SBL (Service
Blanking = ON), so the lower part of the test picture is no
longer visible. Then adjust the Vertical Slope. Align for the
horizontal line in the middle of the test picture to line up with
the boundery between the (still visible) upper part of the
screen and the (invisible) lower part of the screen. Range
from 0 to +63. After this, switch the SBL to OFF again.
Next, align the following horizontal screen geometry settings:
1. HSH (Horizontal Shift): Adjust for the horizontal centre of
the screen, range from 0 to +63.
Page 61

7. LCP (Lower Corner Parabola): Align for the vertical lines in
the lower corners of the screen to be straight. Range from
0 to +63.
8. EWT (East-West Trapezium): Align for equal length of the
horizontal lines in the upper and lower parts of the screen.
Range from 0 to +63.
Now, select “Double Lines” mode, and again align the following
vertical screen geometry setting:
1. VS (Vertical Slope); First activate menu item SBL (Service
Blanking = ON), so the lower part of the test picture is no
longer visible. Then adjust the Vertical Slope. Align for the
horizontal line in the middle of the test picture to line up with
the boundery between the (still visible) upper part of the
screen and the (invisible) lower part of the screen. Range
from 0 to +63. After this, switch the SBL to OFF again.
8.3.3White Tone
In the WHITE TONE sub menu, the colour values for the
different colour temperatures can be changed.
The colour temperature mode (NORMAL, DELTA COOL,
DELTA WARM) can be selected per colour (R, G, and B) with
the RIGHT/LEFT cursor keys. The mode or value can be
changed with the UP/DOWN cursor keys.
First, the values for the NORMAL colour temperature must be
selected. Then the offset values for the DELTA COOL and
DELTA WARM mode can be selected. Note that the alignment
values are non-linear.
8.3.4Sound
No adjustments needed. Use the given default values:
•AF-M = 250
•A2T = 400
•AT = 2
8.3.5Smart Settings
No adjustments needed.
8.4Option Settings
8.4.1Introduction
The microprocessor communicates with a large number of I
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.
•All changes are disregarded when the OPTIONS submenu
is left without using the STORE command.
•The new options setting is only active after the TV is
switched "off" and "on" again with the Mains switch (the
EAROM is then read again).
8.4.2Changing Options
Options are used to control the presence / absence of certain
features and hardware. There are two ways to change the
option settings. All changes in the option settings are saved by
selecting STORE and pressing the CURSOR RIGHT key.
Some changes will only take affect after the set has been
switched OFF and ON with the mains switch (cold start).

Alignment
Normally, no adjustments are needed.
If the white tone alignment values used in CSM of the the TV
set do not give the required result, use the following alignment
method:
1. Set the external pattern generator to a 100% white pattern,
and connect its RF output to the aerial input of the TV. Set
the amplitude to at least 1 mV
frequency to 475.25 MHz. Use system PAL B/G if possible,
otherwise match the system of your generator with the
received signal in the set.
2. Set "Smart Picture" to "Natural".
3. Set "Dynamic NR" to "off".
4. Put the set in the SAM mode.
5. Select via the WHITE TONE menu, the PATTERN submenu.
6. Set PATTERN to "on".
7. Set NORMAL GREEN to "0".
8. Measure with the colour analyser (Minolta CA100 Colour
Analyser or equivalent), calibrated with the spectra, on the
centre of the screen.
9. Adjust with the cursor left/right command the Red and Blue
register for the right xy-coordinates (see the table below).
10. Repeat the white tone adjustment also for the colour
temperatures COOL and WARM.
Table 8-1 White tone alignment (with colour analyser)
Changing Multiple Options by Changing Option Byte
Values
Option Bytes (OB) makes it possible to set all options very fast.
An option byte represents a number of different options. All
options are controlled via option bytes (OB1 to OB13; each
“OB” number represents 16 bits; bit numbers that are not used
are omitted in the second column). Select an Option Byte you
want to change with the CURSOR UP/DOWN keys, and key in
the new value. See the table for more details. An explanation
per option is listed in paragraph "Option Bit Definition".
Changing a Single Option
It is also possible to change an option one at a time. Therefore,
select the option with the CURSOR UP/DOWN keys and
change its setting with the LEFT/RIGHT keys.

9.1Introduction
The L06.1E is a 100 Hz widescreen CRT based HD prepared
TV set for the year 2006. Its CRT has a “RF” (Real Flat) screen,
with 29 and 32 inch screen formats.
The set has the following styling: SL6.
Pixel Plus technology is used for improved picture quality.
This TV set is based on the LSP of the ES1 (which in its turn is
based on the A02).
It has a new SSB. The SSB is no longer directly attached to the
LSP, but has been moved to a separate position in the TV set.
Flatcables are used for the connections between the LSP and
the SSB.
9.2Small Signal Board
For a description of the deflection circuits, the correction
circuits and the X-ray protection circuits of the LSP, see the
ES1 manual. For a description of the remaining LSP circuits,
see the A02 manual, on which the ES1 was based.
For a description of the new SSB, see the circuit diagrams in
chapter 6 and the general description below.
9.1.1General description of the SSB
The L06.1E chassis has a new SSB, with respect to the SSB
used in the ES1 chassis. This SSB is based on the Trident and
a new processor Reneas (instead of the Painter processor
used in the L05 chassis).
The main functionalities of the SSB are:
•RF tuner, RF/AV decoder, 3D comb filter, AV interface for:
2 SCART connectors, 1 Side AV (for SVHS and
headphone); HD YPbPr/LR; HDMI/DVI plus LR Audio,
•Up-scaler (uses PQ registers in Trident),

9.3Software Upgrading
In this chassis, you can upgrade the software via the IAP tool
(In Application Programming). This offers the possibility, to
replace the entire SW image without having to remove the
flash-RAM from its socket. You can find more information on
this in Chapter 5 ("Service Modes, Error Codes, and
Faultfinding") in the paragraph “IAP Tool”.
