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 that during a repair:
•Connect the set to the mains 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 lead for external
damage.
•Check the strain relief of the mains cord for proper function.
•Check the electrical DC resistance between the mains plug
and the secondary side (only for sets which have a mains
isolated power supply):
1. Unplug the mains cord and connect a wire between the
two pins of the mains plug.
2. Set the mains switch to the "on" position (keep the
mains cord unplugged!).
3. Measure the resistance value between the pins of the
mains plug and the metal shielding of the tuner or the
aerial connection 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 plug.
•Check the cabinet for defects, to avoid 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
2.3.1General
•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.
•Manufactured under license from Dolby Laboratories.
“Dolby”, “Pro Logic” and the “double-D symbol”, are
trademarks of Dolby Laboratories.
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 Electrical
Replacement Parts List. Therefore, always check this list
when there is any doubt.
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, it is essential when
removing an (LF)BGA, 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 chance of warping the PWB.
To do this, we recommend that the board is heated until it is
certain that all the joints are molten. Then carefully pull the
component off the board with a vacuum nozzle. For the
appropriate temperature profiles, see the IC data sheet.
Area Preparation
When the component has been removed, the vacant IC area
must be cleaned before replacing the (LF)BGA.
Removing an IC often leaves varying amounts of solder on the
mounting lands. This excessive solder can be removed with
either a solder sucker or solder wick. The remaining flux can be
removed with a brush and cleaning agent.
After the board is properly cleaned and inspected, apply flux on
the solder lands and on the connection balls of the (LF)BGA.
Note: Do not apply solder paste, as this has shown to result in
problems during re-soldering.

-6
),
).
Directions for Use
EN 5LC4.5E AA3.
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

subscription). After login, select “Magazine”, then go to
“Workshop Information”. Here you will find Information on how
to deal with BGA-ICs.
2.3.4Lead Free Solder
Philips CE is going to produce lead-free sets (PBF) from
1.1.2005 onwards.

space on a board also 3 mm is possible.
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 not to avoid, clean carefully 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
short 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 mix of
two alloys).
Regardless of this logo (is not always present), one must treat
all sets from this date onwards according to the following rules.
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 at least a solder-tip temperature of 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 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 rise drastically and flux-fluid will be destroyed. To
3.Directions for Use
You can download this information from the following websites:
Caution: For BGA-ICs, you must use the correct temperatureprofile, which is coupled to the 12NC. For an overview of these
profiles, visit the website www.atyourservice.ce.philips.com
(needs subscription, but is not available for all regions)
You will find this and more technical information within the
"Magazine", chapter "Workshop information".
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 - reactions that are best avoided. Before reaching
into a powered TV set, it is best to test the high voltage
insulation. It is easy to do, and is a good service precaution.

The foam bars (order code 3122 785 90580) can be used for
all types and sizes of Flat TVs. By laying the plasma or LCD TV
flat on the (ESD protective) foam bars, a stable situation is
created to perform measurements and alignments. By first
placing a mirror flat on the table under the TV you can easily
see if something is happening on the screen.

5.4ComPair
5.4.2Specifications
ComPair consists of a Windows based fault finding program
and an interface box between a PC and the (defective) product.
The ComPair interface box is connected to the PC via a serial
(or RS232) cable.
For this chassis, the ComPair interface box and the TV
communicate via a bi-directional service cable via the service
connector(s).
The ComPair fault finding program is able to determine the
problem of the defective television. ComPair can gather
diagnostic information in two ways:
•Automatic (by communication with the television): ComPair
can automatically read out the contents of the entire error
buffer. Diagnosis is done on I
access the I
send and receive I
2
C/UART bus of the television. ComPair can
2
C/UART commands to/from the micro
2
C/UART level. ComPair can
controller of the television. In this way, it is possible for
ComPair to communicate (read and write) to devices on
2
the I
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.
Beside fault finding, ComPair provides some additional features like:
•Up- or downloading of pre-sets.
•Managing of pre-set lists.
•Emulation of the (European) Dealer Service Tool (DST).
•If both ComPair and Force/SearchMan (Electronic Service
Manual) are installed, all the schematics and the PWBs of
the set are available by clicking on the appropriate
hyperlink.
Example: Measure the DC-voltage on capacitor C2568
(Schematic/Panel) at the Mono-carrier.
– Click on the “Panel” hyperlink to automatically show
the PWB with a highlighted capacitor C2568.
– Click on the “Schematic” hyperlink to automatically
show the position of the highlighted capacitor.
5.4.1Introduction
ComPair (Computer Aided Repair) is a service tool for Philips
Consumer Electronics products. ComPair is a further
development on the European DST (service remote control),
which allows faster and more accurate diagnostics. ComPair
has three big advantages:
•ComPair helps you to quickly get an understanding on how
to repair the chassis in a short time by guiding you
systematically through the repair procedures.
•ComPair allows very detailed diagnostics (on I
is therefore capable of accurately indicating problem areas.
You do not have to know anything about I
yourself because ComPair takes care of this.
•ComPair speeds up the repair time since it can
automatically communicate with the chassis (when the
microprocessor is working) and all repair information is
directly available. When ComPair is installed together with
the Force/SearchMan electronic manual of the defective
chassis, schematics and PWBs are only a mouse click
away.

C commands
5.4.3How to Connect
This is described in the chassis fault finding database in
ComPair.
Note: If you encounter any problems, contact your local
support desk.
5.5Error Codes
The error code buffer contains all errors detected since the last
time the buffer was erased. The buffer is written from the left to
the right. When an error occurs that is not yet in the error code
buffer, it is displayed on 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 OSD
display to time out between entries while keying the
sequence).
– Make sure the menu item CLEAR is highlighted. Use
the CURSOR UP/DOWN buttons, if necessary.
– Press the CURSOR RIGHT button to clear the error
buffer. The text on the right side of the “CLEAR” line will
change from “CLEAR?” to “CLEARED”
•If an error does not re-occur within 50 hours it is deleted
from the error buffer.

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 indicate (by
blinking) 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 at 12 short blinks.
5.5.3Error 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).

Service Modes, Error Codes, and Fault Finding
5.7Fault Finding and Repair Tips
Notes:
•It is assumed that the components are mounted correctly,
with correct values and with 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.
Table 5-3 NVM editor overview
HexDecDescription
.ADR0x000A10Existing value
.VAL0x00000New value
.StoreStore?
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.
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 via the AC Power switch.
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 switch.
5. When the set has started, the P+/Ch+ button can be
released and the short circuit of the SDM jumpers can be
removed.
6. The red LED will be on continuously to indicate that the
download is initiated (normally when SDM is activated the
red LED will start with the Blinking LED sequence).
7. Wait +/- 30 s (time needed to download default values to
the NVM).
No Picture Display
1. Check the RGB signal.
2. If it is present, check 3-IC7016 (NE555).
3. If it has output, the problem is in SCALER part.
4. Otherwise, check H-out on pin 2 of NE555. If the input
signal of pin 2 is present, but no output, the IC is defect.
Note:
•If the H-out (pin 67) doesn’t have signal or the level is low,
check the output of NE555 (pin 3) during start up.
•If the H-out (pin 67) has a signal (or has a signal for a very
short time), change IC7016 (NE555).
No TV but PC is Present
1. Check if HSYNC and VSYNC are present at pin 3 of 7017
and 7015.
2. If they are present, check RGB output.
3. If there is no RGB output, the IC TDA120xx can be defect.
5.7.5Power Supply
This power supply contains two fuses. One is near the AC
Power (or mains) inlet connector 1308 and the other is near
connector 1307.
1. Check with power supply in “off” state by means of ohmic
measurement.
2. Fuse 1400 may open in case of severe lightning strikes
and/or failures in the power supply.
3. Fuses 1401 may open in case of a problem with the Standby Supply. Replacement of the fuse is needed, but not
before the cause of the overload conditions has been
resolved.
5.7.3Tuner and IF
No Picture in RF Mode
1. Check whether picture is present in AV. If not, go to Video
processing troubleshooting section.
2. If present, check that the Option settings are correct.
3. Check that all supply voltages are present.
4. Check if I
5. Manually store a known channel and check if there is IF
output at Tuner pin 11.
6. Feed in 105 dBuV at Tuner pin 11 and check whether there
is RGB output from Video Processing IC. If yes, Tuner may
be defect. Replace Tuner.
Required System is not Selected Correctly
1. Check whether a Service jumper (#4022, 0805 size) is
present. If yes, remove it.
5.7.4Video Processing
No Power
1. Check +12 V and 3V3 at position 1910.
2. If no supply, check the connector 1910.
3. If it is correct, check the power supply board.
Power Supply is Correct but no Green LED
1. Check if connectors 1005 and 1601 are properly inserted.
2. If yes, check if the 3V3 is present.
2
C lines are working correctly (3.3V).

8.2.2White Tone
Method 1 (with colour analyser):
1. Supply a 100% white uniformity test signal (100 IRE white)
to the tuner.
2. Enter SAM menu (colour features are switched “off”
automatically).
3. Do NOT change the SMART PICTURE, ACTIVE
CONTROL, and CONTRAST+ settings to prevent
activating of Green Enhancement, Blue Stretch, and Black
Stretch.
Offset values in NVM are used for HD-, HDMI-, and VGA mode,
therefore only the settings in TV mode need to be set.
Make the following settings in the normal user menu, when the
television is in TV Mode:

After the alignment is finished, switch the set to STANDBY, in
order to store the alignments.
Note: When you disconnect the power before you have
switched the set to STANDBY, the settings will not be stored.
Method 2 (without colour analyser):
If you do not have a colour analyser, you can use the default
values. These values are based on the average values in
production.
•Set the values for the NORMAL colour temperature. Given
in the table “Average statistical values for NORMAL” from
production.
•Set the delta values for the COOL and WARM mode. See
table: “Fixed delta values.”
After the alignment is finished, switch the set to STANDBY, in
order to store the alignments.
Note: When you disconnect the power before you have
switched the set to STANDBY, the settings will not be stored.

1. Measure with a calibrated (phosphor- independent) colour
analyser (e.g. Minolta CA-200) in the centre of the screen
(use a contactless analyser, e.g. Minolta CA-210, to align
the LCD TV). The analyser may not touch the screen, and
the measurement must be done in a dark environment.
Note: The colour analyser must be calibrated for the LCD
or Plasma panel in question. See the manual of the colour
analyser for the procedure on how to perform this
calibration.
2. Leave the value with the lowest output on the initial value.
3. Align the NORMAL white points, by lowering the other two
colours, to the right x-y coordinates (see table "White Tone
alignment values").
Note: To prevent clipping of the colour, these values must
only be lowered!

The PLL tuner UR1316 (with FM radio) delivers the IF-signal,
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 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. Two SCARTconnectors are used: SCART1 is fully equipped and SCART2
is meant for VCR. Pin 10 of SCART2 is used for Easylink (P50)
and there is a possibility for Y/C in. The CVBS-out on pin 19
can be used for WYSIWYR (What You See Is What You
Record).

The video part delivers the RGB signals to the Scaler IC.
The Genesis GM1501 Malibu Scaler IC can receive two video
input signals: SDTV (from the Hercules), DVI (from an external
DVI source), or PC (from an 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
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.
Power supply input are several DC voltages coming from a
supply panel.

wrong. The AGC-setting could also be mis-aligned if the picture
deforms with perfect signal. In that case, the IF-amplifier
amplifies too much, resulting in a distorted video-signal.
For Service, this supply panel is a black box. When defect a
new panel must be ordered.
9.4Input/Output
The I/O is divided over two parts: Rear I/O and Side I/O. The
rear has two SCART inputs, a PC (VGA) input, a DVI input, and
an Audio input. The side has a CVBS and Y/C (SVHS) input.
EXT1: The input of SCART1 is CVBS + RGB + L/R and the
output is the video (+ sound) signal from the tuner
(SC1_CVBS_RF_OUT).
EXT2: The input of SCART2 is Y/C + CVBS + L/R. The output
signal is CVBS_SC2_MON_OUT (+ sound).
SCART2 is meant for VCR and has therefore some additional
signals in relation to EXT1 but no RGB: it has the possibility for
Y/C_in: Y_in on pin 20 and Chroma_in on pin 15.
The selection of the external I/O's is controlled by the Hercules.
PC (VGA) in: This input is directly going to the Scaler IC. See
paragraph “Video: Scaler Part”.
9.5Tuner and IF
A Philips UR13xx Tuner with second input (for FM Radio) is
used in the TV board. The SIF and FM signals are decoded by
the Hercules. Tuning is done via I
2
C.
9.5.1Video IF Amplifier
The IF-filter is integrated in a SAW (Surface Acoustic Wave)
filter. One for filtering IF-video (1328) and one for IF-audio
(1330). 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 possibly the AGC setting is

Circuit Descriptions, Abbreviation List, and IC Data Sheets
The video processing is completely handled by the Hercules
•IF demodulator.
•Chrominance decoder
•Sync separator.
•Horizontal & vertical drive.
•RGB processing.
•CVBS and SVHS source select.
It has also build in features like:
•CTI.
•Black stretch.
•Blue stretch.
•White stretch.
•Slow start up.
•Dynamic skin tone correction etc.
Further, it also incorporates sound IF traps and filters, and
requires only one crystal for all systems.
9.6.1Histogram (YUV Picture Improvement) IC
The demodulated video-signal can be checked on pins 74, 75,
and 76 of IC7011 and is fed to pins 70, 71, and 72. In this path,
the Histogram IC TDA9171 is inserted.
This TDA9178 can control various picture improvements:
•Histogram processing.
•Colour transient improvement.
•Luminance transient improvement.
•Black and white stretch.
•Skin tone correction.
•Green enhancement.
•Blue stretch.
•Smart peaking.
•Video dependent coring.
•Colour dependent stretching.
Since the TDA9171 is connected to the Hercules, picture
improvement works only for signals that are routed trough the
Hercules and not for signals directly connected to the Scaler.
EN 65LC4.5E AA9.
9.7Video: Scaler Part (Diagram A7 and A13)
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 ( in a
CRT-based TV, the deflection circuit would do this). 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 67LC4.5E AA9.
9.7.1Features
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
9.7.2Inputs
Analog RGB
The RGB input is fed to pins B2, C2 and D2. 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.
PC (VGA) Input
The VGA input is processed by the VGA block of the Scaler.
The Scaler supports pixel frequencies up to 165 MHz.
YPbPr format is also supported via the VGA interface and
covers a resolution of 480p/560p/720p/1080i.
9.7.3Output
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.
9.8Audio Processing
Hercules
•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 any more 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
being 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 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
the region. AP China can have a Multi-System and an I/DK
version. For India, it might only be BG standard.

Figure 9-4 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:

and limited features for the AV Stereo
9.8.3Audio Amplifier
The audio amplifier part is very straightforward. It uses the
integrated power amplifier TDA7297D, and delivers a
maximum output of 2 x 15 W
RMS
.
The maximum operating condition for this amplifier is 20 V
unloaded. Normal operating supply is from 6.5 V to 18 V.
Muting is done via the SOUND_ENABLE line connected to pin
13 of the amplifier-IC and coming from the Hercules.

9.8.4Audio: Lip Sync (Optional)
A “lip sync” circuit with an audio delay can be added (not for all
models/regions), in order to synchronise with video delay due
to the complexity of the display processing. This video delay is
significant, due to memory based processing. For instance, the
“frame rate conversion” causes a delay of two frames, while the
LCD panel response also causes a delay.
The circuit is a (16 bit) FIFO based digital delay. E.g.: the
memory size required for a 80 ms delay (with a data clock of
1.024 MHz) can be calculated with: Memory size = delay time
* f_clk. This gives: 80 ms * 1.024 MHz = 81920 bits.
To calculate the memory size for a 16 bits mode I
audio stream we must use the following data:
•f_s = 32 kHz, 16 bits, stereo
•Data clock = 32 kHz * 16 * 2 = 1.024 MHz
•Memory size for 1 ms delay = 1 ms * 1.024 MHz = 1024 bits
= 1 kbit
So, the delay time of 80 ms can be built with five steps of 16
ms, which is close to the frame rate. Therefore, a 128 kbit
SRAM (16 x 8) is chosen.

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.
