Safety Instructions, Warnings, and Notes
2.Safety Instructions, Warnings, and Notes
Index of this chapter:
2.1 Safety Instructions
2.2 Warnings
2.3 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.
Safety regulations require that after a repair, the set must be
returned in its original condition. Pay in particular attention to
the following points:
•Route the wire trees correctly and fix 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.
•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.
2.2Warnings
•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 the danger of a
circuit becoming unstable.
2.3Notes
2.3.1 General
•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 color 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.
2.3.2Schematic 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
nano-farads (n= 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.
2.3.3BGA (Ball Grid Array) ICs
Introduction
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.
BGA Temperature Profiles
For BGA-ICs, you must use the correct temperature-profile,
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.
2.3.4Lead-free Soldering
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 stabilize 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 stabilized 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.

),
).
Page 5
Directions for Use
EN 5LC4.8L LA3.
•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
clear the solder-joint from old tin and re-solder with new tin.
2.3.5 Alternative BOM identification
The third digit in the serial number (example:
AG2B0335000001) indicates the number of the alternative
B.O.M. (Bill Of Materials) that has been used for producing the
specific TV set. In general, 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 suppliers. This will then
result in sets which have the same CTN (Commercial Type
Number; e.g. 28PW9515/12) but which have a different B.O.M.
number.
By looking at the third digit of the serial number, one can
identify which B.O.M. is used for the TV set he is working with.
If the third digit of the serial number contains the number “1”
(example: AG1B033500001), then the TV set has been
manufactured according to B.O.M. number 1. If the third digit is
a “2” (example: AG2B0335000001), then the set has been
produced according to B.O.M. no. 2. 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.
Identification: The bottom line of a type plate gives a 14-digit
serial number. Digits 1 and 2 refer to the production center (e.g.
AG is Bruges), digit 3 refers to the B.O.M. code, digit 4 refers
to the Service version change code, digits 5 and 6 refer to the
production year, and digits 7 and 8 refer to production week (in
example below it is 2006 week 17). The 6 last digits contain the
serial number.

2.3.6Board Level Repair (BLR) or Component Level Repair
(CLR)
If a board is defective, consult your repair procedure to decide
if the board has to be exchanged or if it should be repaired on
component level.
If your repair procedure says the board should be exchanged
completely, do not solder on the defective board. Otherwise, it
cannot be returned to the O.E.M. supplier for back charging!
2.3.7Practical Service Precautions
•It makes sense to avoid exposure to electrical shock.
•Always respect voltages. While some may not be

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.
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.

5.6 Fault Finding and Repair Tips
5.1Test Points
In the chassis schematics and layout overviews, the test points
(Fxxx) are mentioned. In the schematics, test points are
indicated with a rectangular box around “Fxxx” or “Ixxx”, in the
layout overviews with a “half-moon” sign.
As most signals are digital, it will be difficult to measure
waveforms with a standard oscilloscope. Several key ICs are
capable of generating test patterns, which can be controlled via
ComPair. In this way it is possible to determine which part is
defective.
Perform measurements under the following conditions:
•Service Default Mode.
•Video: Color bar signal.
•Audio: 3 kHz left, 1 kHz right.
5.2Service Modes
Service Default mode (SDM) and Service Alignment Mode
(SAM) offers several features for the service technician, while
the Customer Service Mode (CSM) is used for communication
between the call centre and the customer.
This chassis also offers the option of using ComPair, a
hardware interface between a computer and the TV chassis. It
offers the possibilities of structured troubleshooting, error code
reading, and software version readout for all chassis.
Minimum requirements for ComPair: a Pentium processor, a
Windows OS, and a CD-ROM drive (see also paragraph
"ComPair").
5.2.1Service Default Mode (SDM)
– Hotel / hospital mode.
– Auto shut off (when no “IDENT” video signal is
received for 15 minutes).
– Skipping of non-favorite 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

5.3Service Tools
5.3.1ComPair
Introduction
ComPair (Computer Aided Repair) is a Service tool for Philips
Consumer Electronics products. and offers the following:
1. ComPair helps you to quickly get an understanding on how
to repair the chassis in a short and effective way.
2. ComPair allows very detailed diagnostics and is therefore
capable of accurately indicating problem areas. You do not
have to know anything about I2C or UART commands
yourself, because ComPair takes care of this.
3. ComPair speeds up the repair time since it can
automatically communicate with the chassis (when the uP
is working) and all repair information is directly available.
4. ComPair features TV software upload possibilities.
Specifications
ComPair consists of a Windows based fault finding program
and an interface box between PC and the (defective) product.
The (new) ComPair II interface box is connected to the PC via
an USB cable. For the TV chassis, the ComPair interface box
and the TV communicate via a bi-directional cable via the
service connector(s).
The ComPair fault finding program is able to determine the
problem of the defective television, by a combination of
automatic diagnostics and an interactive question/answer
procedure.
How to Connect
This is described in the chassis fault finding database in
ComPair.

Caution: It is compulsory to connect the TV to the PC as
shown in the picture above (with the ComPair interface in
between), as the ComPair interface acts as a level shifter. If
one connects the TV directly to the PC (via UART), ICs will be
blown!
Note: If you encounter any problems, contact your local
support desk
5.3.2LVDS Tool
Introduction
This Service tool (also called “ComPair Assistant 1“) may help
you to identify, in case the TV does not show any picture,
whether the Small Signal Board (SSB) or the display of a Flat
TV is defective. Thus to determine if LVDS, RGB, and sync
signals are okay.
When operating, the tool will show a small (scaled) picture on
a VGA monitor. Due to a limited memory capacity, it is not
possible to increase the size when processing high-resolution
LVDS signals (> 1280x960). Below this resolution, or when a
DVI monitor is used, the displayed picture will be full size.
How to Connect
Connections are explained in the user manual, which is packed
with the tool.
Note: To use the LVDS tool, you must have ComPair release
2004-1 (or later) on your PC (engine version >= 2.2.05).
For every TV type number and screen size, one must choose
the proper settings via ComPair. The ComPair file will be
updated regularly with new introduced chassis information.
How to Order
•LVDS tool (incl. two LVDS cables: 31p and 20p):
3122 785 90671.
The error code buffer contains all errors detected since the last
time the buffer was erased. The buffer is written from left to
right. When an error occurs that is not yet in the error code
buffer, it is displayed at the left side and all other errors shift one
position to the right.
5.4.1How to Read the Error Buffer
You can read the error buffer in 3 ways:
•On screen via the SAM (if you have a picture).
Examples:
– ERROR: 0 0 0 0 0 : No errors detected
– ERROR: 6 0 0 0 0 : Error code 6 is the last and only
detected error
– ERROR: 9 6 0 0 0 : Error code 6 was detected first and
error code 9 is the last detected (newest) error
•Via the blinking LED procedure (when you have no
picture). See “The Blinking LED Procedure”.
•Via ComPair.
5.4.2How to Clear the Error Buffer
The error code buffer is cleared in the following cases:
•By using the CLEAR command in the SAM menu:
– To activate SAM, press the following key sequence on
the remote control transmitter: “062596” directly
followed by the OSD/STATUS button (do not allow the
display to time out between entries while keying the
sequence).
– Make sure the menu item CLEAR is highlighted. Use
the MENU UP/DOWN buttons, if necessary.
– Press the MENU RIGHT button to clear the error
buffer. The text on the right side of the “CLEAR” line will
change from “CLEAR?” to “CLEARED”
•If the contents of the error buffer have not changed for 50
hours, the error buffer resets automatically.
Note: If you exit SAM by disconnecting the mains from the
television set, the error buffer is not reset.

Service Modes, Error Codes, and Fault Finding
EN 15LC4.8L LA5.
5.4.3 Error Codes
In case of non-intermittent faults, write down the errors present
in the error buffer and clear the error buffer before you begin
the repair. This ensures that old error codes are no longer
present.
If possible, check the entire contents of the error buffer. In
some situations, an error code is only the result of another error
and not the actual cause of the problem (for example, a fault in
the protection detection circuitry can also lead to a protection).

5.5The Blinking LED Procedure
Using this procedure, you can make the contents of the error
buffer visible via the front LED. This is especially useful when
there is no picture.
When the SDM is entered, the front LED will blink the contents
of the error-buffer:
•The LED blinks with as many pulses as the error code
number, followed by a time period of 1.5 seconds, in which
the LED is “off”.
•Then this sequence is repeated.
Any RC command terminates this sequence.
Example of error buffer: 12 9 6 0 0
After entering SDM, the following occurs:
•1 long blink of 5 seconds to start the sequence,
•12 short blinks followed by a pause of 1.5 seconds,
•9 short blinks followed by a pause of 1.5 seconds,
•6 short blinks followed by a pause of 1.5 seconds,
•1 long blink of 1.5 seconds to finish the sequence,
•The sequence starts again with 12 short blinks.
5.6Fault 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.
5.6.1NVM Editor
In some cases, it can be convenient if one directly can change
the NVM contents. This can be done with the “NVM Editor” in
SAM mode. With this option, single bytes can be changed.
Caution:
•Do not change the NVM settings without
understanding the function of each setting, because
incorrect NVM settings may seriously hamper the
correct functioning of the TV set!
•Always write down the existing NVM settings, before
changing the settings. This will enable you to return to the
original settings, if the new settings turn out to be incorrect.

Service Modes, Error Codes, and Fault Finding
5.6.2Load Default NVM Values
It is possible to download default values automatically into the
NVM in case a blank NVM is placed or when the NVM first 20
address contents are "FF". After the default values are
downloaded, it is possible to start-up and to start aligning the
TV set. To initiate a forced default download the following
action has to be performed:
1. Switch “off” the TV set with the mains cord disconnected
from the wall outlet (it does not matter if this is from
"Standby" or "Off" situation).
2. Short-circuit the SDM jumpers on the SSB (keep short
circuited).
3. Press “P+” or “CH+” on the local keyboard (and keep it
pressed).
4. Reconnect the mains supply to the wall outlet.
5. Release the “P+” or “CH+” when the set is “on” or blue LED
is blinking.
When the downloading has completed successfully, the set
should be into Standby, i.e. red LED on.
Alternative method (1):
1. Go to SAM.
2. Select NVM Editor.
3. Set ADR (address) to 0001 (dec, 4 digit).
4. Change the VAL (value) to 170 (dec, 3 digit).
5. Store the value (via CURSOR RIGHT).
6. Do a “hard reset” to make sure new default values took
place.
Alternative method (2):
It is also possible to upload the default values to the NVM with
ComPair in case the SW is changed, the NVM is replaced with
a new (empty) one, or when the NVM content is corrupted.
After replacing an NVM (or with a defective/no NVM), default
settings should be used to enable the set to start-up and allow
the Service Default Mode and Service Alignment Mode to be
accessed.
5.6.3Tuner and IF
No Picture Display (blank screen with correct sound
output)
1. Check whether the user menu is visible.
2. If the user menu is OK, activate Teletext mode.
3. If teletext is OK, the problem is in the ADC (B18) &
Columbus 3D combfilter (B19), if present (depending on
model, see also paragraph “Teletext Path” in chapter 9).
4. If the user menu is not visible, check if the LCD panel
backlight is ON.
5. If the backlight is OFF, the problem is in the power supply
board or LCD panel. Also check pin 12 (LAMP_ON_OFF)
of 1J02. It should be HIGH during normal operation.
Note: For faultfinding purposes, it is important to know the
following: in Pixel Plus and Digital Crystal Clear models, which
have an ADC (B18) and Columbus 3D combfilter (B19), the
digital input of the Scaler is used for the digital video path
(Hercules output), whereas the analogue RGB input (analogue
input of the scaler) is only used for Teletext. This means that no
mixed mode (video plus Teletext simultaneously) is possible. If
there is sound and Teletext, but no video and user menu (blank
screen), the digital path (Hercules - ADC - Columbus - Scaler)
is faulty. If there is sound but no Teletext, the back-end part
(Scaler - LCD panel) is faulty. In Crystal Clear models, which
do not have an ADC and Columbus, the RGB path (analogue
input of scaler) is used for both video and teletext.
No TV, but PC is Present
1. Check if Hsync_SDTV and Vsync_SDTV are present at pin
1 & pin13 of 7E03.
2. If they are present, check Teletext output.
3. If there is no Teletext output, the IC TDA150xx may be
defect.
5.6.5Power Supply
In case the power supply does not work, check (apart from the
obvious fuse-check) if the oscillators in IC7001 (in TV sets with
37 inch screens) or in IC7001 and IC7U01 (in TV sets with 42
inch screens) are working. If not, replace the ICs.
No Picture in RF Mode, but there is a Noise Raster
1. Check whether picture is present in AV. If not, go to Video
processing troubleshooting section.
2. If picture is present, check if the Option settings are correct.
3. If correct, check if all the supply voltages are present (3.3/
5/8/12/33 V).
4. Check if the I
5. Manually store a known channel and check if there is IF
output at Tuner pin 11.
6. Check the tuning DC voltage at pin 2 of the Tuner. The DC
voltage should vary according to the frequency/channel
being chosen.
7. If the tuning voltage is OK, check the tuner output, pin 11.
8. If it has no output, the Tuner may have a defect. Change
the Tuner.
Required System is not Selected Correctly
Check whether a Service jumper (#4204 and 4205, 0805 size)
is present (diagram B2, location C9). If yes, remove it.
5.6.4Video Processing
No Power
1. Check +12 V and 3V3 at position 1J02.
2. If no supply, check the connector 1J02.
3. If it is correct, check the Power Supply board.
Power Supply is Correct, but no Green LED
1. Check if the connectors 1K00 are properly inserted.
2. If they are inserted correctly, check if the 3V3 is present.
2
C lines are working correctly (3.3 V).

General: The Service Default Mode (SDM) and Service
Alignment Mode (SAM) are described in chapter 5. Menu
navigation is done with the Cursor Up, Down, Left or Right keys
of the remote control transmitter.
8.1General Alignment Conditions
Perform all electrical adjustments under the following
conditions:
8.3Software Alignments
With the software alignments of the Service Alignment Mode
(SAM) the Tuner, White Tone, and Audio settings can be
aligned.
•Connect the set to the mains via an isolation transformer
with low internal resistance.
•Allow the set to warm up for approximately 15 minutes.
•Measure voltages and waveforms in relation to correct
ground (e.g. measure audio signals in relation to
AUDIO_GND).
Caution: It is not allowed to use heatsinks as ground.
•Test probe: Ri > 10 Mohm, Ci < 20 pF.
8.2Hardware Alignments
There are no hardware alignments foreseen for this chassis.
To store the data: Use the RC button “Menu” to switch to the
main menu and next, switch to ‘Stand-by’ mode.

Alignments
8.3.2Tuner
Purpose: To keep the tuner output signal constant as the input
signal amplitude varies.
AGC (RF AGC Take Over Point) alignment:
•Activate the SAM menu.
•Go to the sub-menu “Tuner”.
•Select the “AGC” sub-menu.
•Set the “AGC” value to “27” (default).
•Set the “IFPLL” value to “32” (default).
•Switch the set to “Stand-by” to store the data.
8.3.3 White Tone
Before alignment, set:
•“Brightness” to “60”.
•“Color” to “50”.
•“Contrast” to “60”.
•“Contrast+” to “Off”.
•“Active CTR” to “Off” (via RC).
•“Auto Picture” to “Soft”
Alignment:
•Activate SAM.
•Select “White Tone” and choose a color temperature.
•Use a 100% white screen as input signal and set the
following values: All “White point” values initial to “180” for
Non-Pixel-Plus sets and “245” for Pixel-Plus sets.
Table 8-3 Tint settings for Pixel-Plus sets (37” and 42”)
The table below shows a number of NVM settings used for
each model of TV set. Be sure to use the correct editor in the
SAM menu (NVM Editor or SC NVM Editor), because the first
one is used for the Hercules NVM, and the second one for the
SCALER (SC) part of the TV set.
Caution:
•Do not change the NVM settings without
understanding the function of each setting, because
incorrect NVM settings may seriously hamper the
correct functioning of the TV set!
•Always write down the existing NVM settings, before
changing the settings. This will enable you to return to the
original settings, if the new settings turn out to be incorrect.
232 (37”)
251 (42”)
In case you have a color analyzer:
•Measure with a calibrated (phosphor- independent) color
analyzer (e.g. Minolta CA-210) in the centre of the screen
(for LCD the analyzer may not touch the screen).
Consequently, the measurement needs to be done in a
dark environment.
•Adjust the correct x,y coordinates (while holding one of the
White point registers R, G or B on the initial value) by
means of decreasing the value of one or two other white
points to the correct x,y coordinates (see table “White D
alignment values”).
•Repeat this step for the other color Temperatures that need
to be aligned.
•When finished return to the SAM root menu and press
STANDBY on the RC to store the aligned values to the
NVM.
If you do not have a color analyzer, you can use the default
values. This is the next best solution. The default values are
average values coming from production (statistics).
•Set the RED, GREEN and BLUE default values per
temperature according to the values in the “Tint settings”
table.
•When finished return to the SAM root menu and press
STANDBY on the RC to store the aligned values to the
NVM.

8.3.6Options
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:
The new option setting becomes active after the TV is switched
"off" and "on" again with the mains switch (the EAROM is then
read again).
When the NVM is replaced, all options will require resetting. To
be certain that the factory settings are reproduced exactly, you
must set all option numbers. You can find the correct option
numbers in table “Option Codes OP1...OP7“ below.
How to Change an Option Byte
An option code (or “option byte”) represents eight different
options (bits). When you change these numbers directly, you
can set all options very quickly. All options are controlled via
seven option numbers (OP1... OP7).
Activate SAM and select “Options”. Now you can select the
option byte (OP1.. OP7) with the CURSOR UP/ DOWN keys,
and enter the new 3 digit (decimal) value. For the correct
factory default settings, see the table “Option codes
OP1...OP7“ below. For more detailed information, see the
second table “Option codes at bit level“. If an option is set
(value “1”), it represents a certain decimal value.
When all the correct options (bits) are set, the sum of the
decimal values of each Option Byte (OP) will give the option
code.
Leaving the “Option” submenu saves the changes in the Option
Byte settings. Some changes will only take effect after the set
has been switched “off” and “on” with the AC power switch (cold
start).
If you wish to know which features or settings of the
HERCULES are changed via OP1...OP7, or if you want to
change each option or feature Bit by Bit, use the more detailed
table “Option codes overview” table.
Note: the next table “Option codes at bit level) contains only
that part of the NVM settings that can be changed.

9.1Introduction
The LC4.8 is a global LCD TV chassis. It is the successor of the
LC4.6 LCD TV and has screen sizes of 32 inch to 42 inch (in
16:9 ratio). There are two different picture qualities available,
depending on the model: Pixel Plus and Digital Crystal Clear.
The block diagram below (see Figure “Block diagram”) shows
the Pixel Plus architecture; the architecture of the Digital
Crystal Clear model is shown in the block diagram on the next
page (see Figure “Block diagram of the internal building
blocks”).
Note: Because this is a global chassis, this manual has a
“general” set-up. Therefore, some parts might not be applicable
for some regions (e.g. SCART, SECAM, or Teletext for nonEurope countries). Please take this into account when reading
it.
Notes:
•Only new circuits (circuits that are not published recently)
are described.
•Figures can deviate slightly from the actual situation, due
to different set executions.
•For a good understanding of the following circuit
descriptions, please use the wiring, block (chapter 6) and
circuit diagrams (chapter 7). Where necessary, you will find
a separate drawing for clarification.
The architecture consists of a TV and Scaler panel, I/O panel,
Side I/O, Local Keyboard panel and Power Supply panel.
The functions for video/audio processing, microprocessor (uP),
and CC/TXT decoder (country dependent) are all combined in
one IC (TDA150xx, item 7217), the so-called third generation
Ultimate One Chip (UOC-III) or “Hercules”. This chip has the
following features:
•Control, small signal, mono/stereo, and extensive Audio/
Video switching in one IC.
•Upgrade with digital sound & video processing.
•Alignment free IF, including SECAM-L/L1 and AM.
•FM sound 4.5/5.5/6.0/6.5, no traps/bandpass filters.
•Full multi-standard color decoder.
•One Xtal reference for all functions (microprocessor, RCP,
TXT/CC, RDS, color decoder, and stereo sound
processor).

The PLL tuner UV1316E/1318SD/TEDE9 delivers the IFsignal, via audio & video SAW-filters, to the Video Signal
Processor and FLASH embedded TEXT/Control/Graphics
Micro Controller TDA120x1 (item 7011, also called Hercules).
This IC has the following functions:
•Analogue Video Processing
•Sound Demodulation
•Audio Interfaces and switching
•Volume and tone control for loudspeakers
•Reflection and delay for loudspeaker channels
•Micro Controller
•Data Capture
•Display
The Hercules has one input for the internal CVBS signal and a
video switch with three external CVBS inputs and a CVBS
output. All CVBS inputs can be used as Y-input for Y/C signals.
However, only two Y/C sources can be selected because the
circuit has two chroma inputs. It is possible to add an additional
CVBS(Y)/C input (CVBS/YX and CX) when the YUV interface
and the RGB/YPRPB input are not needed. There are two rear
analogue video inputs: AV is for SVHS in and video (CVBS) in,
and CVI-1 is meant for RGB/YUV in). The rear VIDEO OUT
cinch connector can be used for monitoring purposes:
WYSIWYR (What you see is what you record).
Depending on the model of the TV set, the Hercules delivers its
RGB signals either directly to the Scaler IC or indirectly, via a
Columbus chip (for 2D/3D comb filtering and spatial/temporal
noise reduction, for its description: see further down in this
text). The EPLD, which is present in the Pixel Plus models
discussed in this manual, provides additional sharpening to the
picture. For a general outline, see the table and the block
diagrams below, in which the architectures of the various
models are given, together with their electronic building blocks.

The Hercules, and EEPROM are supplied with 3.3 V, which is
also present during STANDBY.
The EEPROM, or NVM (Non Volatile Memory) is used to store
the settings.
The sound part is built up around the Hercules. The Source
Selection, Decoding and Processing are all done by the
Hercules.
Power supply input are several DC voltages coming from a
supply panel.
9.3Input/Output
The I/O is divided over two parts: Rear I/O and Side I/O. The
rear has two AV inputs with CVBS, Y/C and YUV, a PC (VGA)
input, and an HDMI input. The side has a CVBS and Y/C
(SVHS) input.
The selection of the external I/O's is controlled by the Hercules.
AV1 / CVI-1: The input of AV1 / CVI-1 is CVBS + YUV + L/R.
AV2: The input of AV2 is Y/C + CVBS + L/R.
PC-VGA/CVI-2: This input is directly going to the Scaler IC.
See paragraph “Video: Scaler Part”.
HDMI in / PC-D: This input is directly going to the Scaler IC.
See paragraph “Video: Scaler Part”.
9.4Tuner and IF
The VIF/SIF signals are decoded by the Hercules. Tuning is
done via I
9.4.1Video IF Amplifier
The IF-filter is integrated in a SAW (Surface Acoustic Wave)
filter. One for filtering IF-video (item 1104, in some models:
1105) and one for IF-audio (item 1106). For LATAM however,
one combined filter is used for filtering IF-video and audio (item
1104). The type of the SAW filter depends on the standard(s)
that has(have) to be received.
The output of the tuner is controlled via an IF-amplifier with
AGC-control. This is a voltage feedback from pin 31 of the
Hercules to pin 1 of the tuner. The AGC-detector operates on
top-sync and top-white level. AGC take-over point is adjusted
via the Service Alignment Mode ’Tuner' - 'AGC’. If there is too
much noise in the picture, then it could be that the AGC setting
is wrong. The AGC-setting could also be mis-aligned if the
picture deforms with perfect signal; the IF-amplifier amplifies
too much.

The Genesis GM1501 Malibu Scaler IC can receive the
following video input signals: SDTV (directly from Hercules or
via Columbus), DVI (from an external DVI source), or PC (from
external computer).
After the video processing, the digital data is sent via a Low
Voltage Differential Signalling bus to the LCD panel. LVDS is
used to improve data speed and to reduce EMI significantly.
There are two I
2
C lines and two interrupt and communication
lines (TV_IRQ and TV_SC_COM) for the Scaler control. The
Scaler communicates with the Hercules as a slave device. To
avoid buffer overflow at the Scaler side, the TV_SC_COM line
provides the necessary hardware flow control. To allow bidirectional communication, the Scaler can initiate a service
interrupt-request to the Hercules via the TV_IRQ line.

9.6Columbus
9.6.1 Introduction
The Columbus is a combination of:
•A 2D/3D Comb filter for both PAL and NTSC, and
•A spatial/temporal noise reduction system for both color
and luminance signals.
The Columbus 3D Comb filter uses digitalized CVBS, U, and V
(or C) signals and can be used with or without an external 16
Mbit SDRAM. Without external 16Mbit SDRAM, 3D comb
filtering and temporal noise reduction are not possible.
The noise reduction part of the Columbus is controlled by the
FBX software using the SNERT interface. The 2D/3D Comb
filter part is controlled by the Main software using the I
9.6.22D/3D Comb Filter
Introduction
The “3D Comb filter Columbus” is a combined 2D/3D Comb
filter function that is part of the Columbus chip (circuit diagram
B19, item 7M00). It is a comb filter for both PAL and NTSC.
The 3D Comb filter is used to separate chroma and luminance
components out of a CVBS signal. It is of no use when the
CVBS signal is a SECAM signal (SECAM signals cannot be
combed) The Columbus chip can be used with or without 16
Mbit external SDRAM (circuit diagram B10, item 7B01). When
an external SDRAM is connected to the IC, the Comb filter
function can work in combined 2D/3D processing (depending
on the detected pixel based motion). When no external
SDRAM is connected, only 2D Comb filtering is possible.
The Columbus can comb the following standard signals:
•PAL B, PAL G, PAL H, PAL I, PAL D, PAL K: Color
standard PAL, Color carrier at 4.43 MHz, field frequency:
50 Hz
•PAL M: Color standard PAL, Color carrier at 3.58 MHz, field
frequency: 60 Hz
•PAL N: Color standard PAL, Color carrier at 3.58 MHz, field
frequency: 50 Hz
•NTSC M: Color standard NTSC, Color carrier at 3.58 MHz,
field frequency: 60 Hz
For NTSC signals, the PAL delay line must always be
bypassed.
The following signals CANNOT be combed:
•Double Window signals or Multi PIP. For these signals,
only one part or even no part of the signal is in relation with
2
C bus.
the burst. The part that is not in relation with the burst can
become very blurred when combed by the Columbus
Comb filter. Such a signal must be bypassed. Notch mode
is not even an option since e.g. in double window, one part
can be a PAL signal while the other part is NTSC or
SECAM.
•In cases where a SECAM signal is presented to the
Columbus Comb filter; both the luminance and UV path
must be bypassed. The PAL delay line inside the
Columbus cannot be used for SECAM signals so it must
also be bypassed. The luminance path must have
luminance at its input instead of CVBS. A chroma delay line
outside Columbus must be used for SECAM signals.
Reason for this: the Columbus PAL delay line halves the
output of the chroma signals in case of SECAM.
•Y/C, YPbPr, and RGB signals do not have to be combed.
So both the luminance and UV path must be bypassed.
The PAL delay line will also be bypassed.
•In cases where the Columbus Comb filter does not receive
a CVBS signal with burst at the right place according to the
standard (this includes black and white signals without
burst), phase correction results become unpredictable and
the Comb filter must be set in bypass (= luminance path
bypassed, UV path bypassed, PAL delay line bypassed)
•VCR signals cannot be combed and must be processed in
notch mode, or bypassed.
Columbus Modes
The several modes of the Columbus 3D Comb filter are:
•Bypass mode.
•Band-Pass-Notch mode.
•2D Comb filter modes.
– Simple median.
– Median.
•Field Comb filter mode.
•Frame Comb filter mode.
Bypass Mode
The 3D Comb filter can be set in bypass mode. In this mode,
the CVBS, U and V signals are just bypassed to the output.
Band-Pass-Notch Mode
This is a mode where no Comb filtering is applied. A “Band
Pass Filter” is used to filter the chroma information out of the
CVBS signal. A “Notch Filter” is used to subtract the sub carrier
out of the CVBS in order to make a luminance signal without
chroma sub carrier.
In terms of cross color and cross luminance, this mode has the
worst performance of all. It is only used on these signals where
no comb filtering can be applied (non-standard signals and
most VCR signals for example).
2D Comb Filter Modes
A Comb filter does an action on a current pixel and a delayed
pixel. When the delayed pixel is a line-delayed pixel, we talk
about a “Spatial or 2D Comb Filter” (for NTSC the delay must
be 1 line, for PAL it must be 2 lines).
Spatial or 2D Comb filters show problems on vertical color
transients and on single colored lines. For these situations,
extra hardware is added in the Columbus chip to avoid these
kinds of problems. However even with these extra measures,
there are still situations where the 2D Comb filter does not
perform optimally (diagonal resolution and single lines with
equal luminance content). In order to restrict the working area
of the 2D Comb filter to the frequencies where the sub carrier
is present, a horizontal band pass filter always precedes a 2D
Comb filter.
When a 2D Comb filter has no extra hardware to avoid
problems at vertical color transients (or this extra hardware is
switched “off”), the Comb filter is called a “simple median filter”.
When there is extra hardware to avoid these kinds of problems,
the filter is called a “median filter”.

Circuit Descriptions, Abbreviation List, and IC Data Sheets
Field Comb Filter Mode
A Comb filter does an action on a current pixel and a delayed
pixel. When the delayed pixel is a field-delayed pixel, we talk
about a “Field Comb Filter”. Field Comb filters are only for PAL
of commercial interest.
Field Comb filters show also problems on vertical color
transients and on motion. For the vertical transients, a hanging
dots detector has been added, however the performance on
vertical transients of the field Comb filter, even with this
hanging dots detector, is worse than the performance of the 2D
Comb filter. On motion, the field Comb filter performs very
badly. A motion detector must detect the pixels where there is
motion and on these pixels, the Comb filter must be forced back
to 2D Comb filter mode. This switching back is not
implemented with a hard switch, but with a motion controlled
fader. When there is a lot of motion, the fader will take a lot of
the 2D Comb filter output, when there is less motion, more fieldcombed signal will be taken.
A field Comb filter is also called a “vertical-temporal filter”
because it filters in the vertical and temporal direction.
Frame Comb Filter Mode
A Comb filter does an action on a current pixel and a delayed
pixel. When the delay is a frame, we talk about a “Frame Comb
Filter”. For NTSC we need a delay of one frame, for PAL
however the delay must be two frames.
Frame Comb filters have the best performance, but just like the
Field Comb filter, they perform very badly on motion. A motion
detector will have to detect motion and on these motion pixels,
2D Comb filtering will have to be applied. A frame Comb filter
is a pure “temporal filter”.
The Columbus needs an external memory connected to it,
before it can do a temporal or vertical-temporal Comb filter
action. When no external memory is connected, field or frame
Comb filtering is impossible.
Block Diagram
In the next block diagram, two main parts of the Columbus 2D/
3D Comb filter can be seen:
•The upper part is what is called the luminance Comb filter.
It tries to make an as clean as possible luminance signal
out of the CVBS signal at the input.
•The lower part receives U and V signals (sequentially) that
are normally only band pass filtered in front of the 3D Comb
filter. It filters all left over luminance signals out of it, in order
to make an as clean as possible U and V signal.

on the signals used for temporal (Frame or Field) Comb filtering
(called the temporal phase corrector).
The offset block receives the motion dependant 2D/3D Comb
filtered signal as input. The black level of the luminance signal
is restored and the result is output. The black level restoration
is corrected continuously. However, on VCR signals, this
restoration can become unstable. Therefore, on VCR signals,
a fixed black level restoration value must be forced.
A horizontal dynamic peaking can be done on the luminance
signal. This peaking is adaptive in order not to amplify any
cross luminance distortion. It detects where there could be left
over sub carrier in the luminance signal and reduces the
peaking over there. The detection of the left over cross
luminance is different depending on the pre-filter or post-filter
mode.
The amount of peaking and coring can be chosen. The peaking
algorithm behind it is a simplified copy of the luminance
peaking of picnic. After the peaking block, the signal is output
as clean luminance.
The bypass switches have the obvious purpose of bypassing
the input signal, in case no Comb filtering is wanted.
A PAL delay line is added in the UV path. This is done because
a delay line in front of the 3D Comb filter does need an extra
vertical filter action on the UV signals. This vertical filtering
deteriorates the vertical transient performance for colors. The
Columbus Comb filter cannot undo this. However, this
reduction in performance can be omitted by putting the PAL
delay line after the 3D Comb filter block.
For PAL signals, the PAL delay line in front of the Columbus 3D
Comb filter is bypassed and the Columbus delay line is
switched “on”. In cases where the delay line in front of
Columbus cannot be bypassed, the Columbus PAL delay line
is bypassed.
For NTSC signals, the PAL delay line is bypassed as usual.
9.6.3Noise Reduction and Noise Estimator
The noise reduction function is a sophisticated successor of the
noise reduction module from the PICNIC-chip, also known as
“LIMERIC”.
Besides the noise reduction part, the Columbus noise
reduction module also comprises a noise estimator. This noise
estimator (the LORE-noise estimator) is a new design with the
ambition of more accuracy and with less control complexity
than the existing noise estimators.
The Comb filter has two inputs. One is the CVBS where clean
luminance (Y) will be extracted from; the other one is UV where
a clean U and V signal will be extracted. Both input signals are
digital signals.
The field or frame delay is used for the Field and Frame Comb
filter mode. An external memory connected to the Columbus IC
provides this delay.
Phase correction is done at the inputs of both the Comb filter
blocks. There is a phase correction for spatial filtering (called
the spatial phase corrector) and a separate phase correction
UV-OUT
9.7Video: Scaler Part (Diagram B7, B8 and B9)
The Genesis gm1501 Scaler is a dual channel graphics and
video processing IC for LCD monitors and televisions
incorporating Picture in Picture, up to SXGA output resolutions.
The Scaler controls the display processing in an LCD TV, e.g.
like the deflection circuit in a CRT-based TV. It controls all the
view modes (e.g. like "zooming" and "shifting"). Features like
PC (VGA) or HD inputs, are also handled by this part.

Circuit Descriptions, Abbreviation List, and IC Data Sheets
EN 79LC4.8L LA9.
9.7.1CC/Teletext Path (if present)
In Pixel Plus and Digital Crystal Clear models, which have an
ADC (B18) and Columbus 3D combfilter (B19), the digital input
of the Scaler is used for the digital video signal (Columbus
output), whereas the analogue RGB input of the Scaler is used
for CC/Teletext. This means that no mixed mode (video plus
CC/Teletext simultaneously) is possible. In Crystal Clear
models, which do not have an ADC and Columbus, the
analogue RGB input of Scaler is used for both video and CC/
Teletext (generated by the Hercules). The digital input of the
Scaler is not used in Crystal Clear TV sets. See also the block
diagrams at the beginning of this chapter. When faultfinding,
checking the CC/Teletext path may be useful: if there is sound
and CC/Teletext, but no video and user menu (blank screen),
the digital path (Hercules - ADC - Columbus - Scaler) is faulty.
If there is sound but no CC/Teletext, the back-end part (Scaler
- LCD panel) is faulty.
9.7.2Features
The Scaler provides several key IC functions:
•Scaling.
•Auto-configuration/ Auto-Detection.
•Various Input Ports:
– Analogue RGB.
– Video Graphics.
•Integrated LVDS Transmitter.
•On-chip Micro-controller
9.7.3Inputs
Analogue RGB
The RGB input is fed to pins B2, C2 and D2 of the Scaler IC
(Genesis GM1501, item 7801, see circuit diagram B8). This
input consists of either the Hercules RGB output or the RGB/
YpbPr input of the VGA connector. The Scaler can switch
between the two signals via the PC_HD_SEL signal and
selection IC SM5301 (see circuit diagram B13).

The audio decoding is done entirely via the Hercules. The IF
output from the Tuner is fed directly to either the Video-IF or the
Sound-IF input depending on the type of concept chosen.
There are mainly two types of decoder in the Hercules, an
analogue decoder that decodes only Mono, regardless of any
standards, and a digital decoder (or DEMDEC) that can decode
both Mono as well as Stereo, again regardless of any
standards.
In this chassis, the analogue decoder is used in two cases:
•It is used for AM Sound demodulation in the Europe
SECAM LL’ transmission.
•It is used for all FM demodulation in AV-Stereo sets.

PC (VGA) Input
The VGA input is processed by the VGA block of the Scaler.
The Scaler supports pixel frequencies up to 165MHz.
YpbPr format is also supported via the VGA interface and
covers a resolution of 480p/560p/720p/1080i.
9.7.4Output
The Display Output Port provides data and control signals that
permit the Scaler to connect to a variety of display devices
using a TTL or LVDS interface. The output interface is
configurable for single or dual wide TTL/LVDS in 18, 24 or 30bit RGB pixels format. All display data and timing signals are
synchronous with the DCLK output clock. The integrated LVDS
transmitter is programmable to allow the data and control
signals to be mapped into any sequence depending on the
specified receiver format.
The diversity for the Audio decoding can be broken up into two
main concepts:
•The Quasi Split Sound concept used in Europe and some
AP sets.
•The Inter Carrier concept, used in NAFTA and LATAM.
The UOC-III family makes no difference anymore between
QSS- and Intercarrier IF, nearly all types are softwareswitchable between the two SAW-filter constructions.
Simple data settings are required for the set to determine
whether it is using the Inter Carrier or the QSS concept. These
settings are done via the “QSS” and “FMI” bit found in SAM
mode. Due to the diversity involved, the data for the 2 bits are
placed in the NVM location and it is required to write once
during startup.
On top of that, it can be further broken down into various
systems depending on the region. The systems or region
chosen, will in turn affect the type of sound standard that is/are
allowed to be decoded.
•For the case of Europe, the standard consists of BG/DK/I/
LL’ for a Multi-System set. There are also versions of
Eastern Europe and Western Europe set and the standard
for decoding will be BG/DK and I/DK respectively. FM
Radio is a feature diversity for the Europe sets. The same
version can have either FM Radio or not, independent of
the system (e.g. sets with BG/DK/I/LL’ can have or not
have FM radio).
•For the case of NAFTA and LATAM, there is only one
transmission standard, which is the M standard. The
diversity then will be based on whether it has a dBx noise
reduction or a Non-dBx (no dBx noise reduction).
•For the case of AP, the standard consists of BG/DK/I/M for
a Multi-System set. The diversity here will then depend on
Page 80

Circuit Descriptions, Abbreviation List, and IC Data Sheets
the region. AP China can have a Multi-System and I/DK
version. For India, it might only be BG standard.

and limited features for the AV Stereo
9.8.3Audio Amplifier
The audio amplifier part is very straightforward. It uses two
integrated TDA8931T power amplifiers for the L and R
channels; each amplifier IC is able to deliver a maximum output
of 20 W
continuously in a 4-6 ohm speaker without needing
RMS
a heatsink.
The operating supply for the amplifier may range from 12 V to
32 V; in the LC04x TV set, depending on the model, supply
voltages of 18 V (for the 5 W / 8 ohm version) or 24 V (for the
15 W / 4 ohm version) are used.
Muting is done via the SOUND_ENABLE line connected to pins
7 of both amplifier-ICs, which comes from the Hercules.

9.9.1Hercules
The System Board has two main micro-controllers on board.
These are:
•On-chip x86 micro-controller (OCM) from Genesis LCD TV/
Monitor Controller.
•On-chip 80C51 micro-controller from Philips
Semiconductor UOCIII (Hercules) series.
Each micro-controller has it own I
internal devices.
The Hercules is integrated with the Video and Audio Processor.
For dynamic data storage, such as SMART PICTURE and
SMART SOUND settings, an external NVM IC is being used.
Another feature includes an optional Teletext/Closed Caption
decoder with the possibility of different page storage depending
on the Hercules type number.
9.9.2Block Diagram
The block diagram of the Micro Controller application is shown
below.
Circuit Descriptions, Abbreviation List, and IC Data Sheets
EN 81LC4.8L LA9.
The description of each functional pin is explained below:
•LED. This signal is used as an indication for the Standby,
Remote and Error Indicator. Region diversity:
– During protection mode, the LED blinks and the set is
in standby mode.
– During error conditions it blinks at a predefined rate.
– After receiving a valid RC-5 or local keyboard
command it flashes once.
– For sets with error message indication, the LED blinks
when message is active and the set is in standby
mode.
•SCL. This is the clock wire of the two-wire single master bidirectional I
•SDA. This is the data wire of the two-wire single master bidirectional I
2
C bus.
2
C bus.
•STANDBY. The Hercules generates this signal. This can
enable the power supply in normal operation and disable it
during Standby. It is of logic “high” (3.3 V) under normal
operation and “low” (0 V) during Standby.
•IR. This input pin is connected to an RC5 remote control
receiver.
•SEL-IF. This is an output pin to switch the Video SAW filter
between M system and other systems.
– 0: NTSC M (default)
– 1: PAL B/G, DK, I, L
•NVM_WP. The global protection line is used to enable and
disable write protection to the NVM. When write to the NVM
is required, pin 7 of the NVM must be pulled to logic ‘0’ first
(via Write_Protect of the micro-controller pin) before a write
is performed. Otherwise pin 7 of NVM must always be at
logic “1”
– 0: Disabled
– 1: Enabled (default)
•SOUND_ENABLE. This pin is used to MUTE the audio
amplifier. It is configured as push pull.
•STATUS_1. This signal is used to read the status of the
SCART 1 input.
•STATUS_2. This signal is used to read the status of the
SCART 2 input.
•HERC_RESET. This pin is used to switch the +1.8V
supply.
•POWER_DOWN. The power supply generates this signal.
Logic “high” (3.3 V) under normal operation of the TV and
goes “low” (0 V) when the Mains input voltage supply goes
below 70 V
.

•TV_IRQ. This signal is the interrupt from the Scaler IC.
•TV_SC_COM. This signal is used for the communication
with the Scaler IC.
•EXT_MUTE. This signal is used to reduce the Switch-off
plop.
