To get access to the bottom side (solder side) of the LSP, do
the following (see figure above):
1. Remove the DAF-module (see paragraph 'DAF Assy/
Panel' below).
2. To disconnect the degaussing coil from the LSP, remove
the cable from connector 1502 (1).
3. Release the wiring from their fixation clamps, in order to get
room for repositioning the LSP.
4. Flip the LSP 90 degrees clockwise (2), and place it in the
fixation hole at the left side of the bottom tray (3).
4.3.4Small Signal Board (SSB)
Caution:
Always switch the set completely “OFF” (disconnected the
mains cord) before you remove or replace the SSB.
As the 5V2 standby voltage is always present (while the set is
switched “ON”, in “standby” or in “Protection” mode) on the
SIMM connector, it is very risky to remove the SSB in this
situation, because the risk of short circuiting is very great.
In fact, there is no predefined service position for the SSB. Most
test points are located on the A-side (side that is facing the
tuner). If you have to replace ICs, you must take the complete
SSB module out of the SIMM-connector.
Note: For good access to the A-side, it is necessary to remove
the Auto-SCAVEM bracket (at the left side of the SSB).
Remove the two fixation screws at the bottom by the Auto-

5.5 Error Codes
5.6 The Blinking LED Procedure
5.7 Protections
5.8 Repair tips
5.1Test Points
The chassis is equipped with test points printed on the circuit
board assemblies. They refer to the diagram letters.
Perform measurements under the following conditions:
•Service Default Mode.
•Video: colour bar signal.
•Audio: 3 kHz left, 1 kHz right.
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) is used for communication
between a Philips Customer Care Centre (P3C) and a
customer.
There is also the option of using ComPair, a hardware interface
between a computer (see requirements below) and the TV
chassis. It offers the ability of structured troubleshooting, test
pattern generation, error code reading, software version
readout, and software upgrading.
Minimum requirements: a Pentium processor, Windows 95/
98, and a CD-ROM drive (see also paragraph "ComPair").
Note: In this chassis, two LED configurations are possible: with
bicoloured LED (red/green) or with separate blue and red
LEDs. The bicoloured version is the one we know from EM5E.
The version with blue LED works slightly different. The blue
LED is controlled by software (via ON_OFF_LED). The red
LED will light in anti-phase to the blue one, but with a time
delay. This means that if the blue LED is blinking fast, the red
LED will stay off. But after the blue LED is "OFF" long enough,
the red LED will go "ON".
So take care: In certain service modes (e.g. blinking LED,
stepwise start-up, etc.) you must observe the blue LED and
ignore the red LED.
5.2.1 Service Default Mode (SDM)
Purpose
•To create a pre-defined setting, to get the same
measurement results as given in this manual.
•To override SW protections.
•To start the blinking LED procedure.
Specifications
•Tuning frequency: 475.25 MHz for PAL/SECAM.
•Colour system: SECAM L for France or PAL B/G for the
rest of Europe.
•All picture settings at 50 % (brightness, colour, contrast).
•All sound settings at 50 %, except volume at 25 %.
– Auto switch-off (when no video signal was received for
10 minutes).
– Skip/blank of non-favourite pre-sets.
– Smart modes.
– Auto store of personal presets.
– Auto user menu time-out.
How to enter SDM
•Use one of the following methods:
•Use the standard RC-transmitter and key in the code
"062596", directly followed by the "MENU" button.
Note: It is possible that, together with the SDM, the main
menu will appear. To switch it off, push the "MENU" button
again.
•When you shorten for a moment the two solder pads on the
'external part' of the SSB print, with the indication "SDM".
Activation can be performed in all modes, except when the
set has a problem with the main-processor.
Caution: If the SDM is entered via the pins, all the
software-controlled protections are de-activated.
•Use the DST-emulation feature of ComPair.
•Use the "DEFAULT" button on the Dealer Service Tool
(RC7150).
After entering this mode, "SDM" will appear in the upper right
corner of the screen.
How to navigate
When you press the "MENU" button on the RC transmitter, the
set will toggle between the SDM and the normal user menu
(with the SDM mode still active in the background).
How to exit SDM
Use one of the following methods:
•Switch the set to STANDBY via the RC-transmitter.
•Press the "EXIT" button on the DST.
•Via a standard customer RC-transmitter: key in "00"-
sequence.
5.2.2Service Alignment Mode (SAM)
Purpose
•To perform (software) alignments.
•To change option settings.
•To easily identify the used software version.
•To view operation hours.
•To display (or clear) the error code buffer.
Specifications
•Operation hours counter.
•Software version.
•Option settings.
•Error buffer reading and erasing.
•Software alignments.
How to enter SAM
Use one of the following methods:
•Via a standard RC transmitter: key in the code "062596"
directly followed by the "OSD [i+]" button. After activating
SAM with this method a service warning will appear on the
screen, you can continue by pressing any digit key on the
RC.
•Short for a moment the two solder pads on the 'external
part' of the SSB print, with the indication SAM. Depending
on the software version it is possible that the service
warning will appear, you can continue by pressing any digit
key on the RC.
•Use the DST-emulation feature of ComPair.
•Press the ALIGN button on the DST while the set is in the
normal operation
Service Modes, Error Codes, and Fault Finding
After entering this mode, "SAM" will appear in the upper right
corner of the screen.
Contents of SAM:
•OPERATION HOURS. Displays the accumulated total of
operation hours (not the standby hours).
•HARDWARE INFO
– ROM VERSION. Displays the date of the software and
the software version of the ROM
(Example: EM53EU1-1.0_01234 = AAABBCX.Y_NNNNN).
•AAA= the chassis name.
•BB= the region: EU= Europe, AP= Asia Pacific
PAL/Multi, AN= Asia Pacific NTSC, US= USA, LT=
LATAM.
•C= the language cluster number.
•X.Y= the software version, where X is the main
version number (different numbers are not
compatible with one another) and Y is the sub
version number (a higher number is always
compatible with a lower number).
•NNNNN= last five digits of 12nc code software.
– FBX VERSION. The 12NC-number of the build in
Feature Box software.
•ERRORS (followed by maximal 10 errors). The most
recent error is displayed at the upper left (for an error
explanation see paragraph "Error Codes").
•DEFECTIVE MODULE. Here the module that generates
the error is displayed. If there are multiple errors in the
buffer, which are not all generated by a single module,
there is probably another defect. It will then display the
message "UNKNOWN" here.
•RESET ERROR BUFFER. When you press the "OK"
button, the error buffer is reset.
•ALIGNMENTS. This will activate the "ALIGNMENTS" submenu.
•DEALER OPTIONS. Extra features for the dealers.
•SERVICE OPTIONS. Extra features for Service.
•INITIALISE NVM. When an NVM was corrupted (or
replaced) in the former EM3 chassis, the microprocessor
replaces the content with default data (to assure that the
set can operate). However, all pre-sets and alignment
values are gone now, and option numbers are not correct.
Therefore, this was a very drastic way. In this chassis, the
procedure is implemented in another way: The moment the
processor recognises a corrupted NVM, the "INITIALISE
NVM" line will be highlighted. Now, you can do two things
(dependent of the service instructions at that moment):
– Save the content of the NVM via ComPair for
development analysis, before initialising. This will give
the Philips Service department an extra possibility for
diagnosis (e.g. when Development asks for this).
– Initialise the NVM (same as in the past, however now it
happens conscious).
•STORE. All options and alignments are stored when
pressing the "OK"-button
•FUNCTIONAL TEST. All devices are tested via the "OK"
button. Eventual errors are displayed in the error buffer.
The error buffer is not erased, the content returns when this
test is terminated.
•DAILY MENUS. With the "OK" button, you can go to the
normal user menu. SAM is still active in the background.
With the "MENU" button, you return from the user menu to
SAM menu. This feature can be helpful to quickly change
some settings in the user menu.
•SW MAINTENANCE
– UPGRADE. Not applicable for this chassis
– EVENTS. Not useful for service purposes. In case of
specific software problems, the development
department can ask for this info.
– BDM INFO. Broadcast Debug Menu info. The purpose
of this menu is to debug the broadcast, NOT the TV.
The menu gives an overview of what is received on the
current preset. Following items are displayed:

Service Modes, Error Codes, and Fault Finding
How to exit SAM
Use one of the following methods:
•Press the "MENU" button on the RC-transmitter, or
•Switch the set to STANDBY via the RC-transmitter, or
•Press the "EXIT" button on the DST.
5.2.3 Customer Service Mode (CSM)
Purpose
When a customer is having problems with his TV-set, he can
call his dealer. The service technician can than ask the
customer to activate the CSM, in order to identify the status of
the set. Now, the service technician can judge the severity of
the complaint. In many cases, he can advise the customer how
to solve the problem, or he can decide if it is necessary to visit
the customer.
The CSM is a read only mode; therefore, modifications in this
mode are not possible.
How to enter CSM
Use one of the following methods:
•Press the "MUTE" button on the RC-transmitter
simultaneously with the "MENU" button on the TV (top
control) for at least 4 seconds.
•Key in the code "123654" via the standard RC transmitter.
Note: Activation of the CSM is only possible if there is no (user)
menu on the screen!
How to navigate
By means of the "CURSOR-DOWN/UP" knob on the RCtransmitter, you can navigate through the five menus.

5.4ComPair
•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 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 faultfinding 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.
The ComPair faultfinding 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
can access the I
and receive I
2
C bus of the television. ComPair can send
2
C commands to the micro controller of the
television. In this way, it is possible for ComPair to
communicate (read and write) to devices on the I
of the TV-set.
•Manually (by asking questions to you): Automatic
diagnosis is only possible if the micro controller of the
television is working correctly and only to a certain extends.
When this is not the case, ComPair will guide you through
the faultfinding 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 faultfinding 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 Dealer Service Tool (DST).
•If both ComPair and 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.

5.4.1 Introduction
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.

C commands
5.4.3Stepwise Start-up
Under normal circumstances, a fault in the power supply, or an
error during start-up, will switch the television to protection
mode. ComPair can take over the initialisation of the television.
In this way, it is possible to distinguish which part of the startup routine (hence which circuitry) is causing the problem.
Take notice that the transition between two steps can take
some time, so give the set some time to reach a stable state.
During the transition time the LED can blink strangely.
Stepwise start- up explanation
This is realised via ComPair and is very helpful when a
protection is activated (see also chapter "Protections").

Note (*):
• When the set is in stepwise mode and, due to stepping-up,
a protection is activated, the set will really go into protection
(blinking LED). The set will not leave the stepwise-mode
however. If state X is the state where the set went to
protection, stepwise start-up will return to state X-1. At
state (X-1) diagnostic measurements can be performed.
Also, in the short time the set is in state X but not yet in
protection, you can also do some measurements.

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 0: No errors detected
– 6 0 0 0 0: Error code 6 is the last and only detected
error
– 9 6 0 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 ComPair.
5.5.3How to clear the Error Buffer
Use one of the following methods:
•By activation of the "RESET ERROR BUFFER" command
in the SAM menu.
•With a normal RC, key in sequence "MUTE" followed by
"062599" and "OK".
•When you transmit the commands "DIAGNOSE" - "99" "OK" with ComPair (or with a DST).
•If the content of the error buffer has not changed for 50+
hours, it resets automatically.
5.5.4Error Codes
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).
There are various errors:
2
•I
C device errors.
2
•I
C bus errors.
•Protection errors.
•Errors not related to an I
– BLACK CURRENT LOOP (ERROR 28): detection of a
continuous fail of the black current stabilisation loop of
the HOP.
– FEM (ERROR 26): at start-up, after initialisation of the
PICNIC, the presence of the FALCONIC can be
checked.
– EAGLE (ERROR 27): at start-up, after initialisation of
the PICNIC, the presence of the Eagle can be
checked.

Note:
Error codes 1, 6, or 18 are protection codes and in this case,
supplies of some circuits will be switched "OFF". Also, in
protection, the LED will blink the number of times equivalent to
the most recent error code.
5.6The Blinking LED Procedure
5.6.1 Introduction
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 entered, the front LED will show (blink) the
contents of the error-buffer. Error-codes = 10 are shown as
follows:
•A long blink of 750 ms (which is an indication of the decimal
digit),
•A pause of 1.5 s,
•"n" short blinks (where "n" = 1 - 9),
•When all the error-codes are displayed, the sequence
finishes with a LED blink of 3 s,
•The sequence starts again.
Example: Error 12 9 6 0 0.
After activation of the SDM, the red front LED will show:
•1 long blink of 750 ms (which is an indication of the decimal
digit) followed by a pause of 1.5 s,
•2 short blinks followed by a pause of 3 s,
•9 short blinks followed by a pause of 3 s,
•6 short blinks followed by a pause of 3 s,
•1 long blink of 3 s to finish the sequence,
•The sequence starts again.
Note: If errors 1, 6 or 18 occur, the LED always gives the last
occurred error even if the set is NOT in service mode.
5.6.2 How to Enter
Use one of the following methods:
•Enter the SDM (only via soldering pads marked "SDM" on
SSB). The blinking red front LED will show the entire
contents of the error buffer (this works in "normal
operation" mode and in "protection" mode).
•Transmit the commands "MUTE" - "062500" - "OK" with a
normal RC. The complete error buffer is shown. Take
notice that it takes some seconds before the blinking led
LED starts.
•Transmit the commands "MUTE" - "06250x" - "OK" with a
normal RC (where "x" is a number between 1 and 5). When
x= 1 the last detected error is shown, x= 2 the second last
error, etc.... Take notice that it takes some seconds before
the blinking led LED starts.
•"DIAGNOSE X" with the DST (where "x" is a number
between 1 and 5). When x= 1 the last detected error is
shown, x= 2 the second last error, etc.... When x = 0 all
errors are shown.
5.7Protections
5.7.1Introduction
This chassis has only one microprocessor (OTC), which
remains active during Standby. This because power of the
microprocessor and the attached memory chip set is coming
from the 3V3 supply, which is derived from the 5V Standbycircuitry. Therefore, in both Power-on as in Standby mode, the
microprocessor is connected to this power supply.
If a fault situation is detected, an error code will be generated
and if necessary, the set is put in protection mode. The
protection mode is indicated by the blinking of the front LED at
a frequency of 3 Hz (or by a coded blinking in special cases).
In some error cases however, the microprocessor does not put
the set in the protection mode (this is the case with the hardware - loudspeaker protection of the audio amplifier).
The content of the error buffer can be read via the service menu
(SAM), the blinking LED procedure or via DST/ComPair.
To get a quick diagnosis, this chassis has three service-modes
implemented:
•The Customer Service Mode (CSM).
•The Service Default Mode (SDM). Start-up of the set in a
predefined way.
•The Service Alignment Mode (SAM). In this mode, items
of the set can be adjusted via a menu.
You can enter both SDM and SAM modes via the 'service pads'
on the SSB, via an RC-transmitter (DST or standard RC), or via
ComPair. It is not possible to enter the SAM in "standby"; the
TV has to be in "normal operation" mode.
The "Protection Diagram" shows the structure of the protection
system. See diagram below.

There are several types of protections:
2
•I
C related protections.
•OTC related protections (via polling on I/O pins or via
algorithms).
•HOP related protections (mainly for deflection items).
•Hardware errors that are not sensed by the OTC (e.g.
vertical flyback protection, bridge coil protection, E/W
protection, arcing protection).
All protections are explained below.

(error 16)).
5.7.3 OTC Related Protections
If a protection is detected at an OTC input, the OTC will start to
scan all protection inputs every 200 ms for 5 times. If the
protection on one of the inputs is still active after 1 s, the
microprocessor will put the set in the protection mode.
Before the scanning is started, a so-called "ESD refresh" is
carried out. This is done, because the interrupt on one of the
inputs is possibly caused either by a flash or by ESD. As a flash
or ESD can influence IC settings, the HIP, MSP, 3D Comb (US
only) and wireless module are initialised again, to ensure the
normal picture and sound conditions of the set.
8 V and 5 V protection: The microprocessor senses the
presence of the 8 V and 5 V (via the "+5V_CON" and
"+8V_CON" lines). If one (or both) of these voltages is (are) not
present, an error code is stored in the error buffer of the NVM,
and the set is put in the protection mode.
5.7.4 HOP Related Protections
Every 200 ms, the status register of the HOP is read by the
OTC (via the I

of the inputs of the HOP, the relevant error bit in the HOP
register is set to "high". If this error bit is still "high" after 1 s, the
OTC will store the error code in the error buffer of the NVM and,
depending on the relevancy of the error bit, the set will either
go into the protection mode or not.
The following protections are implemented:
•HFB (Horizontal Flyback): If the horizontal flyback is not
present, this is detected via the HOP (HFB_XRAY_PROT). One status bit is set to "high". The error code
is stored in the error buffer and the set will go into the
protection mode.
•XPR (X-ray protection): If the HFB pulses are too low
(level detection), the HOP will detect this via the XPR-bit.
The error will be logged in the error buffer and the set will
go into protection mode.
Note: Both errors will be logged as HFB-failure.
5.7.5Hardware Related Protections
Due to the architecture ("hot" deflection), some protections
cannot be sensed by the microprocessor. Three of these
protections will lead to a protection on set level (Standby mode
and blinking LED), while another will only lead to a circuit
protection.
TV-set Protection
The following fault conditions will lead to a "complete" set
protection:
•BRIDGECOIL protection: This is sensed via the "EW"
signal going to the base of TS7652 (via R3495 and D6499).
In a normal situation, the voltage on C2498 (diagram A4) is
high and TS7652 is conducting. When bridge coil 5422
(diagram A3) is short circuited, the voltage on C2498
changes to low, which will block TS7652. In this case, also
TS7641 will block and the voltage on 2642 will rise until
TS7443 is forced in conduction. The "SUP-ENABLE"
signal (in normal operating condition -20 V) is shorted now
to ground level, which will force the Main Power Supply to
Standby mode.
•ARC protection: If there are "open" connections (e.g. bad
solder joints) in the high-energy deflection circuitry, this can
lead to damaging effects (read: fire). For that reason, the E/
W current is sensed (via 3479//3480). If this current
becomes too high, the "thyristor" circuit (TS7653 and
TS7654) is triggered. TS7442 is switched "on" and TS7443
is forced into conduction. . The "SUP-ENABLE" signal is
shorted now to ground level, which will force the Main
Power Supply to Standby mode.
•NON_VFB (No vertical Flyback) protection: If the frame
stage generates no pulses, TS7641 will block. TS7443 is
now switched "on", which will lead to Standby mode.
Therefore, in normal operation condition, TS7641 and
TS7652 are conducting, while TS7443 is blocked.
Circuit Protection
The following fault condition will lead to a "partly" set protection:
•PROT1 (DC) protection: When a DC-voltage (positive or
negative) is sensed on one of the loudspeaker outputs, the
protection circuit (TS7704, 7705, 7706 and 7707 in
diagram A6) will put the IC7700 in Standby mode (via tristate input pin 6). For more details, see chapter "Circuit
Descriptions".
5.8Repair tips
5.8.1Miscellaneous
The relay you hear when you switch the set "on" (from Standby
or via the mains switch), is from the degaussing circuitry. It is
not used for switching the Power Supply (as done in the MGchassis).
EN 20EM5.2E AA5.
Service Modes, Error Codes, and Fault Finding
Take care not to touch the "hot" heatsink while disconnecting
the SSB, despite the fact that the mains cord is out of the mains
socket. There can still be an annoying rest-voltage on the
heatsink for a short while. This, because the discharge
resistors 3502 and 3503 (on the LSP between hot and cold
part) are not stuffed for Europe. Instead, discharge resistors
3066 and 3057 on the Mains Switch panel are used, but
because they are located before the Mains switch, they only
discharge when this switch is "on".
Advice: when you remove the SSB, disconnect the Mains
cord, but keep the Mains Switch "on".
Do not try to measure on the SSB side, which is facing the 'hot'
heatsink. This is dangerous. Most service test points are
guided to the 'tuner' side and are indicated by the 'service'
printing.
Where the circuitry was too "crowded" for service printing, you
can find the correct location on the "test point overviews" in this
manual.
A very large part of the LSP is "hot", such as:
•The primary part of the Standby Supply.
•The whole Main supply (except for the secondary Audio
supply).
•And the complete deflection circuitry (so notice that the
deflection coil is hot!).

Figure 5-4 Start-up circuitry
The start up sequence differs from other sets (e.g. MG-sets or
EM2E-sets, but is same as in EM3E-set):
1. When the set is switched "on", the 5 and 8 V lines
("+5V_CON" and "+8V_CON") of the standby power
supply are activated.
2. After the OTC senses them, the P will address the HOP via
2
the I
C-bus, to start the drive [1].
3. Via the "SUP-ENABLE" signal, the Main Supply is switched
"on" and will deliver the V_BAT to the Line deflection stage
[2].
4. EHT generation is now started.
5. The OTC will un-blank the picture.
6. When you switch "off" the set, this is done in a controlled
way via the POR signal [3].
Note: Standby is not directly achieved via the Standby line of
the microprocessor, but indirectly via the HOP circuitry.

5.8.3 ComPair
This chassis does not have an IR transmitting LED (as in MGsets). Therefore, a "Service" (ComPair) connector is
implemented at the rear side of the set, which is directly
accessible (as in A10-, EM2E-, EM3E and EM5E-sets). In
addition to this, there is also a blinking LED procedure to show
the contents of the error buffer.
When you use ComPair, you have the possibility to activate a
"stepwise start-up" mode. With this mode, you can initiate the
start-up sequence step by step. This also means that in certain
steps, some protections are not activated. This is sometimes
very convenient during repair.
5.8.4Protections
Activating SDM via the "service pads" will overrule the
processor-controlled protections, but not the hardware
protections. This means, that the A/D-input protections (5 and
8 V) and the I
2
C "not-acknowledging" info of the feature box
(FBX) and of the Tuner are overruled.
Caution: When doing this, the service technician must know
what he is doing, as it could lead to damaging the set.
The "ARC"- and/or "BRIDGECOIL" protection are hardly ever
triggered, however:
•When you suspect the "ARC" protection, look for bad
solder joints and smell. By interrupting resistor 3497, this
protection is disabled (special attention needed!).
•When you suspect the "BRIDGECOIL" protection, which
can also be due to a too wide picture amplitude, shorten G
and S of the E/W MOSFET 7480. This will disable the
protection. You will now have minimal horizontal amplitude.
Re-align the horizontal amplitude in the SAM menu and
remove the G/S short of TS7480.
5.8.5Main Supply
The simplest way is, to replace the components of the Main
Supply with repair kit 3122 785 90310.
More detailed way:
1. Replace FET 7504 and zener 6505.
2. Remove the SSB panel.
3. Short B and E of TS7529, in order to put the Main Supply
in "on"-mode (TS7529 is blocking then).
Caution: To prevent that R3403 and TS7443 will be
damaged, first disable the HW-protection of the deflection circuit. Therefore short circuit C2642 on the
LSP (diagram A4).
4. Attach a load of 500 O to V_BAT capacitor C2515 (the
supply can not work without a minimum load).
5. Use a variac, and slowly increase the V_MAINS. Measure
over sensing resistors R3514//15, if a nice sawtooth
voltage becomes available.
6. Also measure the V_BAT. This may never exceed +141 V.
If it does, there is something wrong in the feedback circuitry
(e.g. regulator 7506).
Note: Be careful when measuring on the gate of FET TS7504.
This circuitry is very high ohmic and can easily be damaged
(first connect ground to measuring equipment, than measure
the gate).
5.8.6 Standby Supply
The simplest way is to replace the components of the Standby
Supply with repair kit 3122 785 90460.
Service Modes, Error Codes, and Fault Finding
EN 21EM5.2E AA5.
5.8.7 Line Deflection
The simplest way is to replace the components of the Line
Deflection circuitry with repair kit 3122 785 90330.
5.8.8 Frame Deflection
Caution: When the Frame Deflection circuitry is suspected,
one must be careful. Because there is a DC-voltage on the
frame deflection, the beam current could damage the CRT
neck, leading to a defective CRT.
To prevent this from happening, you must:

3. Measure with a multi-meter, or better with a oscilloscope,

In case of a bad connection, it can happen that there is no picture, and that the Standby LED is not
controllable. Re-place the SSB.
You have no picture, so:
- Read the error buffer via ComPair (error buffer is accessible when set is in protection, comparefile will guide you to this)
- Read the blinking LED information via standard remote command <mute>06250X<ok>
- Or you read the error code sequence via standard remote command <mute>062500<ok>.
When you have found the error, check the circuitry related to the supply voltage and I2Ccommunication or the circuitry that triggers the protection.
As processor cannot communicate with one of the 2 busses it the standby-led spontaneously starts
blinking 6-6-6... or 18-18-18... If in the error buffer somewhere is an error 6 or 18, these will have
the highest priority starting the mentioned blinking. Measure dependent of the error on the I2C-bus
which device is loading the bus. (Use I2C -overview)
As the uP cannot communicate with the NVM I2C bus, it spontaneously starts blinking 1-1-1.
Note: when there is no access to the NVM, a lot of picture setting can go wrong.

Perform all electrical adjustments under the following
conditions:
•Power supply voltage: 230 V_ac / 50 Hz (± 10 %).
•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 the 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 the cooling fins/plates as ground.
•Test probe: Ri > 10 Mohm, Ci < 20 pF.
•Use an isolated trimmer/screwdriver to perform the
alignments.
Perform all electrical adjustments with the following start
settings (for all CRTs):
•Set LIGHT SENSOR "off", by setting ACTIVE CONTROL
to "off" with the remote control.
•Set CONTRAST to "75", BRIGHTNESS to "42" and
COLOUR to "54" (via PICTURE menu).
•Set COLOUR ENHANCEMENT to "off" (via PICTURE
menu).
•Set DIGITAL OPTIONS to "Pixel Plus" (via PICTURE
menu), unless otherwise stated (for sets without "Pixel
Plus" (= Eagle), set to "Natural Motion").
•Set DYNAMIC CONTRAST to "off" (via PICTURE menu).
•Set CATHODE DRIVE at "15" (via SAM - Alignments General - Drive - Cathode).
8.1.2 Adjustment Sequence
Use the following adjustment sequence:
1. Set the correct TV-set "options" (after storing, restart the
set!).
Note: The Service Alignment Mode (SAM) is described in
chapter 5 of the Service Manual. Menu navigation is done with
the "CURSOR UP, DOWN, LEFT or RIGHT" keys of the remote
control (RC) transmitter.

8.2.1Vg2 Adjustment
In the frame-blanking period of the R, G, and B signals applied
to the CRT, the "HOP" 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.
1. Go, via the MENU key, to the normal user menu, select
"PICTURE", and set "CONTRAST" and "BRIGHTNESS" to
"0".
2. Activate the SAM.
3. Connect the RF output of a pattern generator to the
antenna input. Test pattern is a "black" picture (blank
screen on CRT without any OSD info).
4. Set the channel of 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 at the "cold" side!.
5. Ground the scope at the CRT panel ("cold" side) and
connect a 10:1 probe to one of the cathodes of the picture
tube socket (see diagram F).
6. Measure the cut-off pulse during first full line after the
frame blanking. You will see two pulses, one being the cutoff pulse and the other being the white drive pulse. Choose
the one with the lowest value; this is the cut-off pulse.
7. Select the cathode with the highest V_dc value for the
alignment. Adjust the V_CUTOFF of this gun with the
SCREEN (lower) potentiometer on the LOT to the correct
DC-value, tolerance is +/- 3 V_dc (align the Vg2 potmeter
first till the flyback lines are just visible and then slowly turn
back until they are gone).

Focus method for Philips 32 inch tube with bleeder gun
You can recognize a CRT with bleeder gun by its type number.
Example:
•W76ERF052X044= with bleeder gun
•W76ERF042X044= with standard gun.
You can also recognize it by the ceramic rectangular plate (this
is the bleeder resistance) you will see inside the gun (viewed
from above).
1. Start the alignment with the STATIC focus (upper
potmeter) turned to the left and the DYNAMIC focus
(middle potmeter) to the right.
2. Adjust the DYNAMIC focus until the horizontal lines at the
centre of the screen have minimum width, without
introducing a visible haze.
3. Adjust the STATIC focus until the vertical lines at the sides
of the screen have minimum width, without introducing a
visible haze.
4. Adjust the DYNAMIC focus until the horizontal lines at the
centre of the screen have minimum width, without
introducing a visible haze.
5. Check overall spot performance and repeat steps 3 and 4
to achieve the best result.
Focus method for all other tubes
1. Start with the STATIC and DYNAMIC focus potentiometers
on the LOT at midway.
2. Adjust the STATIC focus until the vertical lines at the sides
of the screen have minimum width, without introducing a
visible haze.
3. Adjust the DYNAMIC focus until the horizontal lines at the
centre of the screen have minimum width, without
introducing a visible haze.
4. Check overall spot performance and repeat steps 2 and 3
to achieve the best result: a compromise between minimal
visible haze at the middle of the screen and sharp lines at
the edges of the screen.

8.3Software Alignments
8.3.1Introduction
With the software alignments, it is possible to align the
Geometry, White Tone, and Tuner IF settings.
Put the set in the SAM (see chapter 5). The SAM menu will now
appear on the screen. Select, via ALIGNMENTS, one of the
sub-menus. They are explained below in the sequence of the
sub-menus.
Notes:
•All changes to menu items and alignments are stored
automatically, except the option codes. They must be
stored manually.
•If the OPTION CODES have been changed and stored,
the set has to be switched "OFF" and "ON" using the mains
switch to activate the new settings (when switching via
Standby, the option code settings are NOT read by the
microprocessor).
•If an empty EAROM (permanent memory) is detected, all
settings are set to pre-programmed default values.
8.3.2GENERAL
VG2 TEST PATTERN
In this sub-menu, you can turn "On" the OSD feedback for the
Vg2 alignment (see chapter 8.2.1).
ADJUST PEAK WHITE LIMITER
Fixed setting: "9".
EHT COMPENSATION
Enter value "9" for the 28, 29 and 32 inch picture tubes
Enter value "10" for the 36 inch picture tubes.
SOFT CLIPPER
Fixed setting: “Pwl + 0%”
LUMA GAIN
Fixed setting is “1”.
IF AFC
Supply, via an external video generator (e.g. PM5518), a TV
signal with strength of at least 1 mV and a frequency of 475.25
MHz. Use system BG if possible, otherwise match the system
of your generator with the received signal in the set.
Alignment procedure:
1. Go to the user "Installation" menu.
2. Select "Manual Installation".
3. Tune the TV-set to the system and frequency described
above via "Search" - "475" - "OK".
4. If the frequency, showed in the line "Fine tune", is between
475.18 MHz and 475.31 MHz, you do not need to re-adjust
the "IF AFC".
5. If not, adjust the frequency in the "Fine tune" line to 475.25
MHz and "Store" the program (this is very important
because this will disable the AFC algorithm).
6. Now go to the SAM and select ALIGNMENTS - GENERAL
- IF AFC.
7. During the IF AFC parameter adjustment, one can see
OSD feedback in the top of the screen.
8. This OSD feedback can give 4 kind of messages:
Alignments
EN 83EM5.2E AA8.
Table 8-1 OSD feedback of AFC alignment
AFC-windowAFC-frequency vs. reference
OutHigh
InHigh
InLow
OutLow
1. The first item (IN or OUT) informs you whether you are in
or out the AFC-window.
2. The second item (HIGH or LOW) informs you about
whether the AFC-frequency is too high or too low.
3. First, you must align the IF AFC parameter such that you
come into the AFC-window (= IN).
4. Then you must look for the point where the IF AFC
parameter changes from HIGH to LOW. This level is the
value you are looking for.
5. After adjustment, STORE the value.
6. Now return to the user "Installation" menu.
7. Select "Manual Installation" - "Search" - "475" - "OK" and
"Store". This will set the AFC "ON" again.
Service tip: If you do not trust the frequency accuracy of your
service generator, connect it to a "good" TV set and check it
with the "Fine tune"-line.
IF LPRIME AFC
Use the same procedure as for the IF AFC alignment, but set
the video generator to SECAM L/L' (only necessary for
countries that have or can receive this system).
TUNER AGC
1. Set the external pattern generator to a colour bar video
signal and connect the RF output to the aerial input. Set the
amplitude to 10 mV and set the frequency to 475.25 MHz.
2. Connect a DC multimeter between pin 1 and the shielding
of the Tuner (item 1200 on the LSP).
3. Adjust the TUNER AGC value (default value is 25) with the
LEFT/RIGHT cursor keys until the voltage at pin 1 of the
tuner lies between 3.8 and 2.3 V.
4. STORE the alignment.
TUNER AGC TUNER 2 (only for sets with DW/PIP)
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 (this is only applicable for sets with 2-tuner
DW execution).
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 (via the user PICTURE menu).
1. Apply a signal with a 100 % white video-pattern.
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 such, that the
blended signal is 65 % of the black-white amplitude. In
practice, this is about 1.3 V (blended signal) versus 2 V (full
white signal).
4. The parameter can be adjusted in between "0" and "31".
8.3.3 DRIVE (Colour Alignments)
Note: Switch off all (available) colour-influencing features (e.g.
set the TV in ECO-mode).
Method 1 (with colour analyser):
1. Set, via the user menu, the "Contrast" to "100".
2. In SAM, select TEST PATTERN and turn it ON. During the
following alignments, you will see a white block in the
middle of the screen. Measure with the colour analyser on
this area.
3. Set, via the user menu, the "Brightness" to a value between
3.0 and 5.0 Nit (rough setting).
4. Select CATHODE and enter the value "15" (for all picture
tubes).
5. Set the RED, GREEN and BLUE default values to "32".
6. RED BL OFFSET: the Black Level can be aligned very
precisely here. The default value is "7".
7. GREEN BL OFFSET: the Black Level can be aligned very
precisely here. The default value is "7".
8. Select a COLOR TEMPERATURE (e.g. COOL, NORMAL,
or WARM).
9. Adjust the white level via RED, GREEN, and BLUE,
according to the values in table "White levels".
Table 8-2 White levels
ColourTemp.
(K)
X280289313
Y287299329
Method 2 (without colour analyser):
If you do not have a colour analyser, you can use the default
values. This is the next best solution. The default values are
average values coming from production (statistics).
1. Set, via the user menu, the "Contrast" to "100".
2. Select CATHODE and enter the value "15" (for all picture
tubes).
3. RED BL OFFSET: the Black Level can be aligned very
precisely here. The default value is "7".
4. GREEN BL OFFSET: the Black Level can be aligned very
precisely here. The default value is "7".
5. Select a COLOUR TEMPERATURE (e.g. COOL,
NORMAL, or WARM).
6. Set the RED, GREEN and BLUE default values according
to the values in the "Tint settings" table.

8.3.4LUM. 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 =
”8”.
•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 = “10”.
•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 =
“9”.
•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 & white part of the test
area are at the same position. Default value = “7”.

8.3.5 GEO-NOR (Normal Geometry)
Note: Use for all geometry alignments an external pattern
generator with a geometry pattern (e.g. crosshatch).
Align the vertical centre and height of the picture.
1. Use V. AMPLITUDE to align the vertical amplitude so that
the entire test pattern is visible.
2. Set V. SHIFT to value "32".
3. Connect a voltmeter (V_dc) between R3624 and "hot"
ground.
4. Adjust the DC voltage to "0" with potmeter R3642 (see
figure 8-1).
5. Use V. SHIFT again to align the test pattern roughly
vertically in the middle.
6. Repeat the alignment if necessary.
V. S-CORRECTION
Align for equal blocks on top, middle, and bottom of the picture
tube.

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 INSTALLATION menu, choose SETUP,
press OK, and choose PICTURE TILT. With the use of a
crosshatch test pattern, align it to a correct horizontal picture.
V. SLOPE
Align the zero crossing of the frame deflection to the
mechanical middle of the picture tube.
1. First, set the start conditions for 16:9 sets according to the
table “Vertical S-Correction default value”. Position the
boundary-stripes of the test pattern on the edges of the
picture tube.
2. Align V. SLOPE (during alignment, the lower half of the
picture is blanked) such, that the middle line of the test
pattern is matched with the edge of the pattern transient in
the middle of the picture.
3. Repeat the alignment if necessary.
E_06532_010.eps
110204
H. SHIFT AND H. AMPLITUDE (horizontal alignment)
1. Use H. AMPLITUDE to align the horizontal amplitude so
that the entire test pattern is visible.
2. Use H. SHIFT to align the picture horizontally in the middle.
3. Repeat the H. AMPLITUDE alignment if necessary.
Note: In case the horizontal linearity in wide-screen mode is
out of tolerance, add a "DC-shift correction" panel (3104 328
06230) to connector 1419 of the DAF-panel [diagram I]. On the
DC-shift panel, cut diode 6433 for correction to the right or
diode 6432 for correction to the left.
Caution: Be sure to switch "OFF" the set first. Never plug
in a not pre-aligned module in a playing set!
EAST/WEST ALIGNMENT
1. Use EAST/WEST PARABOLA to align the vertical lines
until straight.
2. Use UPPER EAST/WEST CORNER to align the vertical
lines in the upper corners until straight.
3. Use LOWER EAST/WEST CORNER to align the vertical
lines in the lower corners until straight.
4. Use EAST/WEST TRAPEZIUM to align for a rectangular.
5. Use HORIZONTAL BOW to correct the E/W parabola
such, that it becomes symmetrical.
6. Use HORIZONTAL PARALLELOGRAM to align for straight
vertical lines if necessary.
Repeat steps 1 to 6 if necessary.
Alignments
EN 85EM5.2E AA8.
8.3.6 GEO-4:3 (4:3 geometry alignment in 16:9 sets)
1. Use EAST/WEST PARABOLA to align the vertical lines
until straight.
2. Use UPPER EAST/WEST CORNER to align the vertical
lines in the upper corners until straight.
3. Use LOWER EAST/WEST CORNER to align the vertical
lines in the lower corners until straight.
8.3.7 GEO-SW (Super Wide geometry alignment in 16:9 sets)
You only need to set the following values (if the normal
geometry alignment has been performed correctly):
1. V. S-CORRECTION: enter value of the NORMAL
GEOMETRY alignment.
2. H. AMPLITUDE: enter value of the NORMAL GEOMETRY
alignment subtracted by "1".
3. EAST/WEST PARABOLA: enter value of the NORMAL
GEOMETRY alignment.
8.3.8 GEO-100HZ (Digital Scan geometry alignment)
As all alignments are done in Pixel Plus mode (at 75 Hz), the
100 Hz mode needs an extra alignment:
•Select GEO-100HZ. The set automatically switches to 100
Hz mode.
•V. SLOPE: match the middle line of the test pattern with the
upper edge of this blanking picture.
•After the alignment, return to the previous menu. The set
automatically returns to "Pixel Plus" mode.

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.
•You can set the "hardware related" options via the SAM ALIGNMENTS - OPTIONS or OPTION NUMBERS menu.
•You can set the "software related" options via the SAM DEALER OPTIONS menu.
Notes:
•After changing the option(s), save them with the STORE

exactly, you must set both option number lines. You can find
the correct option numbers on a CRT sticker inside the TV set.
Example: The CRT sticker in the 28PW9502/12 gives the
following option numbers (Note: this is just an example):
12660 16672 49984 00000
04118 00001 00032 18250
The first line (group 1) indicates options 1 to 4, the second line
(group 2) options 5 to 8 (see tables below).
Every 5-digit number represents 16 bits (so maximum number
can be 65536 if all options are set).
When all the correct options are set, the sum of the decimal
values of each Option Byte (OB) will give the option number.

9.1Introduction
This chassis contains, compared to its predecessor, the
following new feature/component:
•FEM (Falconic Embedded Memories): is a new Falconic
with internal Field memories and jagged line removal.
The chassis consists of a full sized LSP/SSP combination and
a smaller double sided four layer SSB, which is mounted on the
SSP using a 80-fold SIMM connector. The main functionalities
are:
•LSP: supply, deflection, and sound amplification.
•SSP: tuner input, SIMM interface, I/O, and interface
provisions for extended functions such as PIP.
•SSB: core TV functionalities, being TXT/control, video and
audio decoding, feature box, video featuring, and sync/
geometry control.
The LSP (single sided) is built up very conventional, with hardly
any surface mounted components on the copper side. Similar
with the EM3 (but different as with the MG-chassis), the EM5
LSP has a very large 'hot' part, including both deflection coils.
The SSB is a high tech module (four layer, 2 sides reflow
technology, full SMC) with very high component density and
complete shielding for EMC-reasons. Despite this, it is
designed in such a way, that repair on component level is
possible. To achieve this, attention was paid to:
•The position of service test lands: most of them are at the
Tuner side.
•Accessibility (Tuner side). If there are still problems with
the accessibility, one can order an extension board (see
parts list).
•Clearance around surface mounted ICs (for replacing).
•Detailed diagnostics and fault finding is possible via
ComPair.
The availability of Double Window (DW) or Picture In Picture
(PIP) depends on the model range. There are two different
executions, depending on the number of tuners:
•One Tuner: The TV has only one tuner (on the LSP), so the
PIP-picture can be either from this tuner or from an external
AV-source.
•Two Tuners: In this case there are two separate tuners, so
the main picture and the DW picture are independently
selectable. The IF signal from the main tuner is processed
on the SSB, while the IF signal from the second tuner is
processed by a second BOCMA video processor on the
DW-panel. The source selection is done via an I/O
expander.
9.2Block Diagram
For the block diagram see chapter 6 “Wiring Diagram, Block
Diagrams, and Overviews”.
The Tuner (item 1200) is a PLL tuner and delivers the IF-signal,
via audio & video SAW-filters, to the HIP (High-end Input
Processor). The HIP has the following functions:
•IF modulation.
•Video source- and record select.
•Colour decoder.
•Synchronisation.
Attached to the HIP is the 2D Comb filter is used to separate
chroma and luminance components out of a CVBS signal.
Three SCART-connectors are available:
•SCART1 is fully equipped,
•SCART2 is meant for VCR. Pin 10 is used for Easylink
(P50) and there is a possibility for Y/C in. The CVBS-out on
pin 19 is meant for WYSIWYR (What You See Is What You
Record).
•SCART3 (if available) is a RGB/CVBS and audio L/R input.
It can be used as second tuner input, in case of a 1-Tuner
DW/PIP set.
After the HIP, we come to the part that is called the Feature box
(diagram B3x):
•For Digital Scan, the PICNIC is required.
•For Natural Motion, the FALCONIC (or FEM) is required.
•For Pixel Plus, the EAGLE is required.
The HIP delivers YUV and sync signals to the PICNIC. This IC
takes care of:
•Analogue to Digital conversion and vice versa.
•50 to 100 Hz conversion.
•Panorama mode.
•Noise reduction.
•Dynamic contrast.
After the PICNIC, the (now 2fH) YUV-signals are fed to the
FALCONIC (or FEM) for “Natural Motion” followed by the Eagle
for “Pixel Plus” enhancement. The processed YUV signals
(from Eagle or PICNIC) are, together with the sync-signals from
the PICNIC, then fed to the HOP (High-end Output Processor).
This IC handles the video control and geometry part. The RGBsignals for TXT/OSD (from the microprocessor) are also
inserted via the HOP. The video part delivers the RGB signals
to the CRT-panel and the geometry part delivers the H-drive, Vdrive, and a drive-signal for rotation.
Both deflection circuits are “hot” and located on the LSP. They
are driven by the HOP. To make a galvanic separation, the Line
Drive is driven via transformer 5410 and the Frame Drive via
transformer 5621.The horizontal output stage generates some
supply voltages and the EHT-, focus- and Vg2-voltages.
The RGB amplifiers on the CRT-panel are supplied with 200 V
from the LOT.
The Scavem circuit modulates transitions of the Luminance (Y)
signal on the horizontal deflection current, giving a sharper
picture.
The sound part is built around the MSP34xx (Multi-channel
Sound Processor) for IF sound detection, sound control and
source selection. Dolby decoding is also done by the MSP.
Amplification is done via a “class D” integrated power amplifier
IC, the TDA7490.
Circuit Descriptions, Abbreviation List, and IC Data Sheets
EN 89EM5.2E AA9.
The microprocessor, called OTC (OSD, Teletext and Control)
takes care of the analogue TXT input- and output processing.
The OTC, ROM, and RAM are supplied with 3.3 V, which is
derived from the +5V2.
The NVM (Non Volatile Memory) is used to store the settings,
one Flash-RAM contains the set software, the other FlashRAM (7012) is for EPG, and the DRAM is used for storing the
Teletext pages.
There is a separate Standby Supply, in order to reduce the
Standby power consumption. During Standby, the Main Supply
is switched “off” (via TS7529).
A relay (1550) is used to switch the degaussing circuit. It is
switched “on” after set start-up and switched “off” by the uP
after 12 s.
The Main Supply, an SMPS based on the “down-converter”
principle, generates the 141 V (V_BAT) and the +/- 16 V for the
audio part.
Note: Voltage V_BAT is not mains isolated (“hot”), but is
alignment free.
9.3Feature Box
The key components of the FBX are the following ICs:
9.4 PICNIC
9.5 FEM (Falconic Embedded Memory)
9.6 Eagle
9.4PICNIC
All FBX versions have the PICNIC as basic IC. All functions
located in the PICNIC are therefore basic functions, and will be
described briefly. These functions are completely controlled by
the built-in microprocessor.
•Clamp. In the PICNIC, three analogue clamp circuits are
integrated that assure a well defined DC level for the
luminance (Y) and colour-difference (U, V) input signals.
•AGC. The AGC in the PICNIC consists of a digital
controlled analogue variable gain amplifier with a gain
range of 9.3 dB, and an algorithm that uses input derived
from histogram data and the overflow detection. It is
designed to assure an optimal ADC input range, for all
input signals, and so having minimal quantisation noise.
•Analogue pre and post filters. The pre filters of the
Feature Box are always the integrated filters of the PICNIC.
The internal post filters of the PICNIC are never used.
•ADC/DAC. Analogue to Digital conversion is done with
three identical 9-bit ADCs, and the Digital to Analogue
conversion uses three identical 10-bit DACs. The Y signal
is mapped on 9 bits for black-to-white range and has room
for over- and undershoots by means of the 10th bit at the
output DACs. The U and V channels are processed in 9-bit
accuracy up to the CTI circuit that has a gain of 2, resulting
in a 10-bit output that suits the 10 bit DACs.
•Time Base Correction. The Time Base Correction circuit
simulates a fast acquisition line locked clock, while the
actual system clock is locked to the input line frequency
with a very large time constant. In this way the typical VCR
problems linked to a one clock Feature Box can be solved,
particularly the deflection circuit (in case of CRT) driven by
the Feature Box can profit from this feature.
•VCR detection. The VCR detection of the PICNIC is an
algorithm that detects the phase jumps (which occurs for
instance with VCRs) to be able to correct the picture
deviations. This detection is done by monitoring the PLL
circuit in the PICNIC by the on-board microprocessor on
several parameters.
•Peaking. The two dimensional peaking can boost or
attenuate higher frequencies in both vertical and horizontal
direction. The lowest setting is a 2D low pass. The higher
settings make sharpening, but the resulting overshoots can
clip relatively fast compared to the dynamic peaking,
because there is no room for overshoot above white and
under black. This peaking is done on field base.
•Digital Noise Reduction (DNR). The PICNIC
accommodates three noise reduction circuits:
– Clinic. This "clamp noise reduction" circuit consists of
an adaptive temporal field recursive filter. It corrects
the DC level of each line, when it is varying from field
to field in the line segments with likely the least
movement. It can be used to correct clamp errors that
cannot be restored by conventional clamp circuits. The
filter is completely autonomous for the user, who can
only switch it “on” or “off”.
– Limeric. This spatial noise reduction circuit is targeted
for reduction of the mid frequency noise spectrum,
where adaptive filtering combines pixels around the
centre pixel and pixels from the lines above in a
recursive way. The quantity of noise reduction is user
defined.
– 2D Coring. This circuit attacks spatial noise in a very
drastic way without distinguishing noise from wanted
resolution. It shaves away small details of any kind,
depending on the amplitude of the detail and the user
setting. So, it is advised to use this feature only at the
lowest settings.
•Histogram Modification. Using histogram modification
techniques in PICNIC, the contrast of the overall picture
may be improved. From a TV scene, the distribution of all
luminance values is taken (histogram). This histogram is
used to calculate an optimal transfer curve for the particular
scene, which is used to process the video digitally resulting
in a picture with improved contrast (called “Dynamic
Contrast”).
•Auto Picture Control. The PICNIC is prepared to make
several APC functions in co-operation with the main
software. This is made by giving relevant video quality data
to main, and by giving several control ‘handles’ to main
microprocessor. In this way, automatic picture quality
settings depending on customer settings and video data
can be made. The following items are prepared in the
AutoTV:
– Automatic Picture Control. This feature controls the
settings for DNR, Limeric, coring, sharpness and
histogram modification as a function of the noise figure
and signal steepness information extracted from the
PICNIC and from external information such as ambient
light.
– Automatic Aspect Ratio Adaptation. This AARA
feature uses data from the black bar detection circuit to
adapt vertical and horizontal amplitude to an aspect
ratio belonging to the display and does not show black
bars. This is done by the control software. Auto Format
is controlled via main software by reading out the black
bar information from the FBX.
•Field Rate Upconversion. In order to remove large area
flicker from the TV screen, the field-rate of the video is
doubled by the Feature Box. A 50/60 Hz video input is
converted to 100/120 Hz. The line frequency (16 kHz) is
also doubled (32 kHz). When the video input contains fields
A, B etc..., the conversion provides an AABB sequence
scanning on the display. The actual up-conversion is done
in the first Field Memory (FM1) by reading it twice at double
speed, while writing once.
•Input Phase. The horizontal phase of the input video
acquisition can be shifted to allow compensation for
processing delay of other components in front of the
Feature Box.
•Miscellaneous Features. To be sure that On Screen
Display (OSD) is always readable, even when no video
signal is received, the feature box can be switched to
stable OSD mode. Free running but stable horizontal and
vertical deflection drive signals will be generated, so that
OSD information and PIP can be displayed jitter free, and
thus clearly readable on the screen. Specially for tuning
purposes and smooth channel switching a stable OSD
mode is implemented that uses the horizontal time base
EN 90EM5.2E AA9.
Circuit Descriptions, Abbreviation List, and IC Data Sheets
correction combined with a slow PLL, and a small vertical
catch window. This mode enables undisturbed reading of
OSD while the set is tuning.
9.5FEM (Falconic Embedded Memory)
The FEM IC (SAA4998) is the successor of the SAA4993H,
and adds ”jagged line removal” and “embedded field
memories” as new/improved features.
9.5.1 Motion Estimation/Compensation
The FEM utilizes a high quality motion estimator. The motion
estimation is applied to eliminate the motion blur of current 100
Hz TV sets and to eliminate the motion judder of movies. This
judder is visible on all television sets and even in a cinema.
Particularly for movies (with only 25 pictures/second), the
increased number of pictures helps to smoothen the motion.
These improvements a.o. lead to a picture performance
improvement on a global scale, with an optimal quality
independent from the received standard (50/60 Hz and/or
video/film) or display mode (field doubling/de-interlaced 1fV).
Especially film judder removal from a 60 Hz input source, the
so-called 3-2 pull down film mode, makes the FEM globally
applicable.
9.5.2 4:2:2 processing
The colour data path in the FEM is implemented in 4:2:2
bandwidth (as in PICNIC). The 4:2:2 mode requires an Field
Memory (FM1) of 16 bits wide.
9.5.3 Upconversion
The FEM is always used in combination with the Eagle.
Therefore, the output is always adapted to the input of the
Eagle. This 2fV/4fH signal is motion compensated. Only 3 out
of 4 fields are correct motion compensated. The Eagle will only
use these three correct motion compensated fields.
9.5.4 Dynamic Noise Reduction
For signals that have been affected by noise, improvement can
be achieved by combining of the pixel values of the current and
past fields of video. This is however only possible for those
picture areas in which no movement occurs. If movement
occurs in some area, only the information from the current field
of video may be displayed for that area to prevent smearing, so
noise reduction is not effective there.
To reduce loss of detail, the high frequencies can be bypassed.
This can be done because the human eye is more sensitive to
noise with low frequencies. The movement detection is
implemented in the luminance channel and in the colour
channel to reduce artefacts such as smearing.
9.5.5 Vertical Peaking
The vertical peaking circuit in FEM works on de-interlaced
data, resulting in a double resolution (compared to PICNIC)
high vertical frequency enhancement.
9.5.6 EDDI
EDDI is an Edge Dependent De-Interlacer. This improved deinterlacer, results in smaller jagged lines for video input
sources (not for film sources!).
9.5.7 Strobe
Having a FEM in the data path, it is easy to create a still picture
or freeze feature. A frame can be frozen once, or, using the
strobe feature, repetitively after a certain programmable
interval of time. The Eagle is used to make “still pictures”.
9.6Eagle
The Eagle has the following features:
•Vertical upscaler. Two fully programmable vertical
upscalers are implemented in the Eagle chip, one for the
luminance signal, and one for the colour difference signals.
However, the number of output lines is never allowed to
exceed 1024 lines per field including blanking. This means
that 1050i/1250i is still possible.
•Vertical Zoom. The vertical zooming is done with the
vertical upscaler of the Eagle instead of using the FEM
upscaling. Zoom factors varying from 1 to 8 can be
selected. Vertical compression is possible in 1fV up to a
factor of 2.
•Interlacer and horizontal upscaler. Two fully
programmable horizontal upscalers are implemented in the
Eagle chip, one for the luminance signal, and one for the
colour difference signals.
•Continuous horizontal zoom/compression. The
horizontal zooming is done with the interlacer and
horizontal upscaler of the Eagle instead of the PICNIC
upscaling. In the Eagle, a digital sample rate converter can
provide horizontal video compression up to 50 %, and up
to 8 times zoom. In compress mode, a part of the screen
remains unused. In this case, parts of the display can be
filled in with a grey value, a colour, or other signal source
that bypasses the Feature Box (TXT or another
compressed picture).
•Panorama. A panoramic horizontal distortion on the
picture can be applied to make a screen-fitting picture,
without having black side panels, or lost video. This is
mainly used to fit 4:3 pictures in a 16:9 display with a
resulting correct aspect ratio in the middle of the screen
and stretched video at the left and right sides. The inverse
feature is called “amaronap” and can also be applied.
•Sub pixel Luminance Transient Improvement (LTI): The
Eagle contains a horizontal and a vertical sub pixel LTI.
•Peaking: In the Eagle both horizontal and vertical
luminance peaking is implemented. The horizontal peaking
equals the peaking of the PICNIC. The vertical peaking is
an addition of two fixed and one 9-taps fully programmable
peaking filters.
– Horizontal luminance peaking: Peaking in Eagle can
be used in two ways:
a. The first way is to give the luminance a linear boost
of the higher frequency ranges, which makes no
distinction between small and large details or
edges.
b. The other way is to use the peaking dynamically, in
order to boost smaller details and provide less gain
on large details and edges. The effect is detail
enhancement without creation of unnatural large
over- and undershoots on large details and edges.
– Vertical luminance peaking: There are three vertical
peaking filters. Two fixed vertical peaking filter and one
fully programmable vertical peaking filter. The three
filters all have their separate gain setting before the
results are added. To avoid excessive gain settings a
high peak suppression can be set to avoid excessive
output results.
•Colour dependent sharpness (CDS): The colour
dependent sharpness circuit increases the luminance
sharpness in saturated red and magenta parts. The
reduction of the normal peaking can be switched “on/off”.
The below given colour features are implemented in all Eagle
chips:
•Digital Colour Transient Improvement (DCTI): DCTI
equals the PICNIC DCTI implementation with improved
control range. The DCTI is done with Eagle i.s.o. PICNIC.
Circuit Descriptions, Abbreviation List, and IC Data Sheets
•Skin tone correction: The idea of Skin tone correction is
to correct UV components corresponding to skin towards
an “ideal” skin tone axis.
•Blue Stretch: This feature makes it possible to shift
colours near white towards more bluish coloured white.
•Green Enhancement: This feature makes it possible to
shift low saturated green colours towards more saturated
green colours.
•Colour Dependent Peaking (CDP): When using
luminance peaking, the viewer has the impression that the
colour performance is somewhat lower then in the picture
generated without the luminance peaking circuit. This
impression is normal because no action was done in the
colour channel to compensate for the change in the
luminance channel. Locally, at the edge position the
contrast has been increased without increase of the
saturation at this point. That is why the viewer perceives
less colour. To give the viewer the same colour impression
as on the original picture, a correction to the colour has to
be done at the same place where a change was made in
the luminance. This is CDP.
•Skin Tone Dependent Peaking (STDP): The horizontal
and vertical peaking can be reduced in skin tone areas to
avoid that people become too old. Attenuation can be
applied to both horizontal and vertical peaking.
