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.
2.3Notes
2.3.1General
•Measure the voltages and waveforms with regard to the
chassis (= tuner) ground (H), or hot ground (I), depending
on the tested area of circuitry. The voltages and waveforms
shown in the diagrams are indicative. Measure them in the
Service Default Mode (see chapter 5) with a colour bar
signal and stereo sound (L: 3 kHz, R: 1 kHz unless stated
otherwise) and picture carrier at 475.25 MHz for PAL, or
61.25 MHz for NTSC (channel 3).
•Where necessary, measure the waveforms and voltages
with (D) and without (E) aerial signal. Measure the
voltages in the power supply section both in normal
operation (G) and in stand-by (F). These values are
indicated by means of the appropriate symbols.
•The semiconductors indicated in the circuit diagram and in
the parts lists, are interchangeable per position with the
semiconductors in the unit, irrespective of the type
indication on these semiconductors.
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.
-9
), or pico-farads (p= x10
-12
-6
),
).
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.
2.3.3Rework on BGA (Ball Grid Array) ICs
General
Although (LF)BGA assembly yields are very high, there may
still be a requirement for component rework. By rework, we
mean the process of removing the component from the PWB
and replacing it with a new component. If an (LF)BGA is
removed from a PWB, the solder balls of the component are
deformed drastically so the removed (LF)BGA has to be
discarded.
Device Removal
As is the case with any component that, is being removed, it is
essential when removing an (LF)BGA, that the board, tracks,
solder lands, or surrounding components are not damaged. To
remove an (LF)BGA, the board must be uniformly heated to a
temperature close to the reflow soldering temperature.
A uniform temperature reduces the risk of warping the PWB. To
do this, we recommend that the board is heated until it is certain
that all the joints are molten. Then carefully pull the component
off the board with a vacuum nozzle. For the appropriate
temperature profiles, see the IC data sheet.
Area Preparation
When the component has been removed, the vacant IC area
must be cleaned before replacing the (LF)BGA.
Removing an IC often leaves varying amounts of solder on the
mounting lands. This excessive solder can be removed with
either a solder sucker or solder wick. The remaining flux can be
removed with a brush and cleaning agent.
Safety Instructions, Warnings, and Notes
EN 5LC4.9U AA2.
After the board is properly cleaned and inspected, apply flux on
the solder lands and on the connection balls of the (LF)BGA.
Note: Do not apply solder paste, as this has been shown to
result in problems during re-soldering.
Device Replacement
The last step in the repair process is to solder the new
component on the board. Ideally, the (LF)BGA should be
aligned under a microscope or magnifying glass. If this is not
possible, try to align the (LF)BGA with any board markers.
So as not to damage neighbouring components, it may be
necessary to reduce some temperatures and times.
More Information
For more information on how to handle BGA devices, visit this
URL: www.atyourservice.ce.philips.com (needs subscription,
not available for all regions). After login, select “Magazine”,
then go to “Repair Downloads”. Here you will find Information
on how to deal with BGA-ICs.
2.3.4Lead-free Solder
Philips CE is producing lead-free sets (PBF) from 1.1.2005
onwards.
Identification: The bottom line of a type plate gives a 14-digit
serial number. Digits 5 and 6 refer to the production year, digits
7 and 8 refer to production week (in example below it is 1991
week 18).
To avoid wear-out of tips, switch “off” unused equipment or
reduce heat.
•Mix of lead-free soldering tin/parts with leaded soldering
tin/parts is possible but PHILIPS recommends strongly to avoid mixed regimes. If this cannot be avoided, carefully
clear the solder-joint from old tin and re-solder with new tin.
•Use only original spare-parts listed in the Service-Manuals.
Not listed standard material (commodities) has to be
purchased at external companies.
•Special information for lead-free BGA ICs: these ICs will be
delivered in so-called "dry-packaging" to protect the IC
against moisture. This packaging may only be opened
shortly before it is used (soldered). Otherwise the body of
the IC gets "wet" inside and during the heating time the
structure of the IC will be destroyed due to high (steam-)
pressure inside the body. If the packaging was opened
before usage, the IC has to be heated up for some hours
(around 90°C) for drying (think of ESD-protection!).
Do not re-use BGAs at all!
•For sets produced before 1.1.2005, containing leaded
soldering tin and components, all needed spare parts will
be available till the end of the service period. For the repair
of such sets nothing changes.
In case of doubt whether the board is lead-free or not (or with
mixed technologies), you can use the following method:
•Always use the highest temperature to solder, when using
SAC305 (see also instructions below).
•De-solder thoroughly (clean solder joints to avoid the
mixing of two alloys).
E_06532_024.eps
230205
Figure 2-1 Serial number example
Regardless of the special lead-free logo (which is not always
indicated), one must treat all sets from this date onwards
according to the rules as described below.
P
b
Figure 2-2 Lead-free logo
Due to lead-free technology some rules have to be respected
by the workshop during a repair:
•Use only lead-free soldering tin Philips SAC305 with order
code 0622 149 00106. If lead-free solder paste is required,
please contact the manufacturer of your soldering
equipment. In general, use of solder paste within
workshops should be avoided because paste is not easy to
store and to handle.
•Use only adequate solder tools applicable for lead-free
soldering tin. The solder tool must be able:
– To reach a solder-tip temperature of at least 400°C.
– To stabilise the adjusted temperature at the solder-tip.
– To exchange solder-tips for different applications.
•Adjust your solder tool so that a temperature of around
360°C - 380°C is reached and stabilised at the solder joint.
Heating time of the solder-joint should not exceed ~ 4 sec.
Avoid temperatures above 400°C, otherwise wear-out of
tips will increase drastically and flux-fluid will be destroyed.
Caution: 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.
2.3.5Practical Service Precautions
•It makes sense to avoid exposure to electrical shock.
While some sources are expected to have a possible
dangerous impact, others of quite high potential are of
limited current and are sometimes held in less regard.
•Always respect voltages. While some may not be
dangerous in themselves, they can cause unexpected
reactions that are best avoided. Before reaching into a
powered TV set, it is best to test the high voltage insulation.
It is easy to do, and is a good service precaution.
EN 6LC4.9U AA3.
3.Directions for Use

yourself because ComPair takes care of this.
3. ComPair speeds up the repair time since it can
automatically communicate with the chassis (when the
microprocessor is working) and all repair information is
directly available. When ComPair is installed together with
the Force/SearchMan electronic manual of the defective
chassis, schematics and PWBs are only a mouse click
away.
Specifications
ComPair consists of a Windows based fault finding program
and an interface box between PC and the (defective) product.
The ComPair interface box is connected to the PC via a serial
(or RS-232) cable.
For this chassis, the ComPair interface box and the TV
communicate via a bi-directional service cable via the service
connector(s).
The ComPair fault finding program is able to determine the
problem of the defective television. ComPair can gather
diagnostic information in two ways:
•Automatically (by communicating with the television):
ComPair can automatically read out the contents of the
entire error buffer. Diagnosis is done on I
ComPair can access the I
ComPair can send and receive I

C/UART 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
2
C/UART buses 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 extent.
When this is not the case, ComPair will guide you through
the fault finding tree by asking you questions (e.g. Does the
screen give a picture? Click on the correct answer: YES /
NO) and showing you examples (e.g. Measure test-point I7
and click on the correct oscillogram you see on the
oscilloscope). You can answer by clicking on a link (e.g.
text or a waveform picture) that will bring you to the next
step in the fault finding process.
By a combination of automatic diagnostics and an interactive
question / answer procedure, ComPair will enable you to find
most problems in a fast and effective way.
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 below (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!

5.4Service Tools
5.4.1 ComPair
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:
1. 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.
2. ComPair allows very detailed diagnostics (on I
is therefore capable of accurately indicating problem areas.
Note: If you encounter any problems, contact your local
support desk.
5.4.2LVDS 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.
Furthermore it is possible to program EPLDs with this tool
(Byteblaster). Read the user manual for an explanation of this
feature.
Since 2004, the LVDS output connectors in our Flat TV models
are standardised (with some exceptions). With the two
delivered LVDS interface cables (31p and 20p) you can cover
most chassis (in special cases, an extra cable will be offered).
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 (>= 1280x768). Generally this tool is intended to
determine if the SSB is working or not. Thus to determine if
LVDS, RGB, and sync signals are okay.
How to Connect
Connections are explained in the user manual, which is
delivered 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.
5.5Error Codes
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.
5.5.1How 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.
5.5.2How 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 enter 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.

5.5.3 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).

5.6The 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 RC5 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.
5.7Fault 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.
5.7.1NVM Editor
In some cases, it can be handy if one directly can change the
NVM contents. This can be done with the “NVM Editor” in SAM
mode. 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!
•Do not change the Scaler NVM settings, as this will
hamper the DVI functionality of the TV set!
•Always note 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.

5.7.2Load Default NVM Values
In case a blank NVM is placed or when the NVM content is
corrupted, default values can be downloaded into the NVM.
(For empty NVM replacement, short the SDM with a jumper
and apply the mains voltage. Remember to remove the jumper
after the reload is completed). After the default values are
downloaded, it will be possible to start up and to start aligning
the TV set. This is no longer initiated automatically; to initiate
the download the following action has to be performed:
1. Switch “off” the TV set by disconnecting the AC Power
plug.
2. Short circuit the SDM jumpers (keep short-circuited).
3. Press P+ or Ch+ on the local keyboard (and keep it
pressed).
4. Switch on the TV set via the AC Power plug.
5. Keep pressing the P+/Ch+ button until the set has started
up and the SDM is shown.
Alternative method:
1. Go to SAM.
2. Select NVM Editor (not SC NVM Editor).
3. Select ADR (address) to 1 (dec).
4. Change the VAL (value) to 170 (dec).
5. Store the value.
6. Disconnect the mains plug and wait for a few seconds.
7. Reconnect the mains plug and wait until the set goes into
its standby mode (red LED lights up).

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 fault finding 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.
Service Modes, Error Codes, and Fault Finding
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.
5.7.5Power 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.

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. For further important NVM
settings, see also the other NVM tables elsewhere in this
manual.
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!
•Do not change the Scaler NVM settings, as this will
hamper the DVI functionality of the TV set!
•Always note 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.

Options OP1...OP7 in the SAM menu can be used for quickly
restoring 64 features or settings of the HERCULES part of the
TV set to their original default factory values (8 groups of 8
features/settings each). When the decimal value of one option
byte OP1...OP7 is changed (see the first table below) then a
group of 8 bits, representing 8 HERCULES options or features,
is changed as well (see the second table below for a detailed
description of the features or settings that are changed).
The second table shows which option byte (OP1...OP7)
represents which group of 8 option bits. Each bit (0...7)
switches a particular HERCULES feature or setting ON or OFF,
depending on its value (1 or 0).
It is also possible to change the features or settings mentioned
in the second table directly at bit level, by means of the NVM
Editor in the SAM menu. In the NVM Editor, first the correct
NVM address (ADR) has to be entered, then the correct value
(VAL, 1 or 0) for each bit (see second table), and finally the
settings have to be stored (STORE). For quickly restoring the
HERCULES part of the TV set to its original factory settings,
however, it is more convenient to simply enter the default
factory settings OP1...OP7 that are given in the first table
below. How to do this, is described in the next paragraph.
How to Change an Option Byte
As has been explained above, an Option byte (OP) represents
a number of different HERCULES options. Changing these
bytes directly makes it possible to set all HERCULES options
very fast. All options are controlled via seven option bytes.
Select the option byte (OP1.. OP7) with the Menu Up/ Down
keys, and enter the new (decimal) value. For the correct
Factory Default settings, see the first table below. For more
detailed information, see the second table.
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).

9.1Introduction
The “LC4.9 Plasma TV” is a global plasma TV for the year
2005. It is the successor of the “LC4.7” and has a screen size
of 42 inch or 50 inch (in 16:9 ratio). It has a new styling, called
Entry+ 05. Globally, there are three different picture qualities
available, depending on the model: Pixel Plus (used in the
models discussed in this manual), Digital Crystal Clear, and
9.2Block Diagram
SDRAM
Crystal Clear. The block diagram below (Figure “Block
diagram”) shows the Pixel Plus architecture; the architectures
of the other models are shown in the block diagram on the next
page (Figure “Block diagram of the internal building blocks”).
The architecture consists of a TV and Scaler panel, an EPLD
(only in the Pixel Plus model), an I/O panel, a Side I/O and
Local Keyboard panel and a Power Supply panel.
The functions for video/audio processing, microprocessor (µP),
and CC/Teletext (TXT) decoder 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 colour decoder.
•One Xtal reference for all functions (microprocessor, RCP,
TXT/CC, RDS, colour decoder, and stereo sound
processor).

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

The Hercules has one input for the internal CVBS signal and a
video switch with 3 external CVBS inputs and a CVBS output.
All CVBS inputs can be used as Y-input for Y/C signals.
However, only 2 Y/C sources can be selected because the
circuit has 2 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

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

The Genesis GM1501 Malibu Scaler IC can receive two 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.
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.

9.4.1Video IF Amplifier
The IF-filter is integrated in a SAW (Surface Acoustic Wave)
filter. One for filtering IF-video (1104, in some models: 1105)
and one for IF-audio (1106). The type of these filters 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.
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”.

9.6Columbus
9.6.1Introduction
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
colour and luminance signals.
The Columbus 3D Comb filter uses digitised 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: Colour
standard PAL, Colour carrier at 4.43 MHz, field frequency:
50 Hz
•PAL M: Colour standard PAL, Colour carrier at 3.58 MHz,
field frequency: 60 Hz
•PAL N: Colour standard PAL, Colour carrier at 3.58 MHz,
field frequency: 50 Hz
•NTSC M: Colour standard NTSC, Colour 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
the burst. The part that is not in relation with the burst can
become very blurred when combed by the Columbus
2
C bus.
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 colour 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 colour
transients and on single coloured 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 colour 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”.
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
Circuit Descriptions, Abbreviation List, and IC Data Sheets
EN 89LC4.9U AA9.
about a “Field Comb Filter”. Field Comb filters are only for PAL
of commercial interest.
Field Comb filters show also problems on vertical colour
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.
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 colours. 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.
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
on the signals used for temporal (Frame or Field) Comb filtering
(called the temporal phase corrector).

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.

EN 91LC4.9U AA9.
9.7.1Teletext Path
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 teletext. This means that no mixed mode (video plus 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 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 fault finding, checking the teletext path may
be useful: 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.
9.7.2Features
The Scaler provides several key IC functions:
•Scaling.
•Auto-configuration/ Auto-Detection.
•Various Input Ports:
– Analog RGB.
– Video Graphics.
•Integrated LVDS Transmitter.
•On-chip Micro-controller
9.7.3Inputs
Analog 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).
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.

Figure 9-6 Block diagram audio processing
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.
9.8.1Diversity
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 start-up.
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 (not applicable for the models discussed in this
manual) is a feature diversity for some Europe TV 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
the region. AP China can have a Multi-System and I/DK
version. For India, it might only be BG standard.

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.
9.8.4Audio: Lip Sync
No Lip Sync adjustments are necessary in this model.
9.9Control
9.9.1Hercules
The System Board has two main micro-controllers on board.
These are:
•On-chip x86 micro-controller (OCM) from Genesis LCD or
plasma 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.

The ports of the Micro Controller can be configured as follows:
•A normal input port.
•An input ADC port.
•An output Open Drain port.
•An output Push-Pull port.
•An output PWM port.
•Input/Output Port
The following table shows the ports used for the LC04 control:
