Safety Instructions, Warnings, and Notes

2. Safety Instructions, Warnings, and Notes

EN 5LC13E 2.

2.1 Safety Instructions

Safety regulations require that during a repair:

• Always 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.

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 and HT cables correctly and fix them

with the mounted cable clamps.

• Check the insulation of the mains lead for external

damage.

• Check the cabinet for defects, to avoid touching of any

inner parts by the customer.

2.2 Warnings

• 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 (on the inverter panel).

• 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 Notes

2.3.1 General

• Clean the LCD display with a slightly humid cloth.

• Measure the direct voltages and oscillograms with regard

to the chassis ground (H), or hot ground (I) as this is
called.

• The direct voltages and oscillograms shown in the

diagrams are indicative. Measure them in the Service
Default Mode (see section “Service Modes”).

• Where necessary, measure the voltages in the power

supply section both in normal operation (G) and in standby
(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.

• 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.

2.3.3 Rework on BGA 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, 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 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.

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.
To reflow the solder, apply a temperature profile according to
the IC data sheet. So as not to damage neighbouring
components, it may be necessary to reduce some
temperatures and times

2.3.2 Schematic 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 expressed in Micro-Farads (µ=

-6

x10

), Nano-Farads (n= x10-9), or Pico-Farads (p= x10

-12

).

4. The “Blinking LED” Procedure

5. ComPair

6. Trouble Shooting Tips

5.1 Test Points

This chassis is equipped with test points in the service printing.
In the schematics test points are identified with a rectangle box
around Fxxx or Ixxx. On the PCB, test points are specifically
mentioned in the service manual as “half moons” with a dot in
the centre.

Measurements are performed under the following conditions:

• Video: colour bar signal.

• Audio: 3kHz left, 1kHz right.

5.2 Service Modes

5.2.1 Limited DST Support

This chassis does still have some limited Dealer Service Tool
(DST) support. The set can be put in two service modes via the
DST (RC7150, this remote is not available anymore). These
are the Service Default Mode (SDM) and the Service Alignment
Mode (SAM).

Installation Features Dealer

For easy installation and diagnosis, the DTS can be used.
When there is no picture (to access the error code buffer via the
OSD), DST can enable the functionality of displaying the
contents of the entire error code buffer via the blinking LED
procedure.

The dealer can use the RC7150 for programming the TV-set
with presets. Ten different program tables can be programmed
into the DST via a GFL or MG TV-set (downloading from the
GFL or MG to the DST; see GFL or MG service manuals) or by
the DST-I. For explanation of the installation features of the
DST, the directions for use of the DST are recommended.

5.2.2 Service Default Mode (SDM)

Purpose of SDM:

• To provide a situation with predefined settings to get the
same measurements as in this manual.

• To start the “Blinking LED” procedure.

• To have the possibility to override the 5V protection

Activating SDM:

• By transmitting the "DEFAULT" command with the RC7150
Dealer Service Tool (this works both while the set is in
normal operation mode or in the SAM).

• Standard RC sequence 0-6-2-5-9-6 followed by pressing
the “MENU”-button (this works both while the set is in
normal operation mode or in the SAM).

• By shorting pins 5 and 6 of connector 1170 of LED/RC
panel. Then apply DC supply from the AC-DC adaptor (not
required to remove the metal shielding).

Note: By temporarily shorting pins 5 and 6 of connector 1170
and then applying DC supply from the AC-DC adaptor, the 5V
protection is disabled.

Caution: Overriding the 5V protection should only be used for
a short period of time. In case of S/W protections (error 4) the
set will shutdown after 15 sec.

For recognition, “SDM” is displayed at the upper right corner of
the screen.

SDM Menu

SDM

CL 36532073_083.eps

Figure 5-1 SDM Menu

SDM, the set will switch to SDM immediately when the mains
is switched on again.

The SDM sets the following pre-defined conditions:

• PAL/SECAM sets: tuning at 475.25 MHz PAL.

• Volume level is set to 25% (of the maximum volume level).

Other picture and sound settings are set to 50%.

The following functions are switched off in SDM (and after
leaving SDM):

• Timer.

• Sleep timer.

The following functions are disabled during SDM (and enabled
after leaving SDM)

• Parental lock.

• Blue mute.

5.3 Errors

5.3.1 Error code buffer

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, the error is written at the left side and all other errors
shift one position to the right.

The error code buffer will be cleared in the following cases:

– By activating the CLEAR ERRORS function in SAM menu.
– By transmitting 0-6-2-5-9-9 with the normal RC.
– By transmitting the commands “DIAGNOSE 99 OK” with

the DST (RC7150) or with ComPair.

– Automatically reset if its contents has not changed for 50

hours.

By leaving SDM or SAM with the mains switch, the error buffer
is not reset.

Examples:
ERROR: 0 0 0 0 0 0 0 : No errors detected
ERROR: 6 0 0 0 0 0 0 : Error code 6 is the last and only
detected error
ERROR: 9 6 0 0 0 0 0 : Error code 6 was first detected and error
code 9 is the last detected (newest) error

The contents of the error buffer can also be made visible
through the “blinking LED” procedure. This is especially useful
when there is no picture. See paragraph 5.4 “The blinking LED
procedure “.

5.3.2 Error codes

In case of non-intermittent faults, clear the error buffer before
starting the repair, to prevent that “old” error codes are present
(it is wise to write down the content of the error buffer before
you clear it). If possible check the entire content of the error
buffers. In some situations an error code is only the result of
another error code (and not the actual cause).
Note: a fault in the protection detection circuitry can also lead
to a protection.

TV-Board

Errors

• Error 0 = No error

• Error 4 = +5V protection. 5V protection active; set is

switched to protection; error code 4 is placed in the error
buffer; the LED will blink 4 times (repeatedly). A 5V failure
can be caused by a drop in the 5V supply output, resulting
in an undefined behaviour of the set. Therefore, all I2C
devices connected to the 5V supply are constantly
monitored. When none of these devices responds to the
micro controller for a prolonged time, the micro controller
assumes that there is a failure in the 5V supply. By starting
up the set with the service jumpers shorted, the 5V
protection is disabled and it is easier to determine the
cause. +5V protection will be activated when these I2C
devices fail (no I2C communication):

– Main Tuner 1100 (diagram A3)
– ITT sound processor MSP34xx IC-7620 (diagram A8)

Service tips: To isolate the problem area after
overriding the +5V protection, determine whether:

1. The +5V source is working properly IC7930
(diagram A10)

2. ITT sound processor circuit is loading the +5V;
isolate coil 5620 (diagram A8)

3. The audio delay IC 7601 - IC7605 is loading the
+5V source; isolate coil 5601 (diagram A7)

4. Main tuner circuit is loading the +5V source; isolate
coil 5122 (diagram A3)
Caution: Overriding the 5V protection when there
is a 5V failure can increase the temperature in the
set and may cause permanent damage to
components. Do not override the 5V protection for
a prolonged time.

• Error 6 = General I2C error. This will occur in the following

cases:

– SCL or SDA is shorted to ground
– SCL is shorted to SDA
– SDA or SCL connection at the micro controller is open

circuit.

• Error 8 = BOCMA IC TDA888xx (diagram A4) I2C

communication failure. BOCMA (IC7301 on TV board) is
corrupted or the I2C line to the BOCMA is low or no supply
voltage present at pin 14 (3V3) or no supply voltage at pin

23.

• Error 9 = BOCMA IC TDA888xx 8V failure (SUP bit). No

supply voltage at pin 53. Check coil 5302.

• Error 10 = NVM I2C error (diagram A1). NVM (EEPROM -

IC7066) does not respond to the micro controller.

• Error 11 = Micro controller / NV Memory identification

error. During the last start-up the NVM and the micro
controller did not recognize each other (e.g. one of them
was replaced or the NVM memory has been changed/
adapted or lost), therefore the NVM was loaded with
default values.

• Error 12 = Microprocessor (Painter - IC 7064) internal

RAM test failure.

• Error 13 =Main Tuner I2C failure UR13xx. Tuner (item

1100, diagram A3) is corrupted or the I2C line to the tuner
is low or no supply voltage at pin 3, pin 6 or 7 of the tuner.

• Error 14 =Sound processor I2C error IC7620 (MSP34xx,

diagram A8). Sound controller does not respond to the
micro controller.

• Error 15 =SRAM IC CY7C1019 test failure (IC7070,

diagram A2).
Note: Only for Europe and AP-PAL execution.

Scaler Board

When the TV detects critical errors from the Scaler board, it will
shutdown into protection mode. After a short period of time, the
LED will blink according to the respective error codes.

Protection errors:

• Error 16 = Video formatter/converter I2C error IC7351

(GENESIS FLI2300, diagram C5).

• Error 17 = Video decoder I2C error IC7302 (Philips

SAA7118E, diagram C3).
Note: BGA IC fixed with a heat sink (see chapter 4 how to
remove).

Service Modes, Error Messages, and Repair Tips

EN 19LC13E 5.

5.4 The “Blinking LED” procedure

The contents of the error buffer can also be made visible
through the “Blinking LED” procedure. This is especially useful
when there is no picture.

When the SDM is entered, the LED will blink the contents of the
error-buffer. Error-codes ≥ 10 are shown by a long blink of
750msec, which is an indication of the decimal digit, followed
by a pause of 1500msec. followed by n short blinks. When all
the error-codes are displayed, the sequence is finished with a
LED display of 3 seconds. The sequence starts again.

Example:

Error code position 1 2 3 4 5
Error buffer: 12 9 6 0 0
This gives after activating SDM: 1 long blink of 750msec +
pause of 1500msec + 2 short blinks - pause of 3 s - 9 short
blinks - pause of 3 s - 6 short blinks - pause of 3 s - long blink
of 3 s - etc.

Note: If errors 1, 2 or 4 occur, the LED always blinks the last
occurred error, even if the set is not in service mode.

Another method of reading out a single error code is to use a
standard RC or a DST.

• Standard RC - Press “0-6-2-5-0-x” in sequence, to read

(blinking LED) out a respective error code in the error
buffer, where x = 1, 2, 3, 4, 5, 6, or 7.

• DST: Press “Diagnose” “x” “OK” to read (blinking LED) out

a respective error code in the error buffer, where x = 1, 2,
3, 4, 5, 6, or 7.

• 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 extend.
When this is not the case, ComPair will guide you through
the faultfinding tree by asking you questions (e.g. Does the

screen give a picture? Click on the correct answer: YES /
NO) and showing you examples (e.g. Measure test-point I7
and click on the correct waveform you see on the
oscilloscope). You can answer by clicking on a link (e.g.

text or a waveform picture) that will bring you to the next

step in the faultfinding process.
By a combination of automatic diagnostics and an interactive
question / answer procedure, ComPair will enable you to find
most problems in a fast and effective way.

Beside fault finding, ComPair provides some additional
features like:

• Up- or downloading of pre-sets.

• Managing of pre-set lists.

• Emulation of the Dealer Service Tool (DST).

• If both ComPair and SearchMan (Electronic Service

Manual) are installed, all the schematics and the PWBs of

the set are available by clicking on the appropriate

hyperlink.

Example: Measure the DC-voltage on capacitor C2568

(Schematic/Panel) at the Mono-carrier.

– Click on the 'Panel' hyperlink to automatically show the

PWB with a highlighted capacitor C2568.

– Click on the 'Schematic' hyperlink to automatically

show the position of the highlighted capacitor.

5.5.3 How To Connect

5.5 ComPair

5.5.1 Introduction

ComPair (Computer Aided Repair) is a service tool for Philips
Consumer Electronics products. ComPair is a further
development on the European DST (service remote control),
which allows faster and more accurate diagnostics. ComPair
has three big advantages:
ComPair helps you to quickly get an understanding on how to
repair the chassis in a short time by guiding you systematically
through the repair procedures.
ComPair allows very detailed diagnostics (on I2C level) and is
therefore capable of accurately indicating problem areas. You
do not have to know anything about I2C commands 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 SearchMan electronic
manual of the defective chassis, schematics and PWBs are
only a mouse click away.

5.5.2 Specifications

ComPair consists of a Windows based faultfinding program
and an interface box between PC and the (defective) product.
The ComPair interface box is connected to the PC via a serial
or RS232 cable.
The ComPair faultfinding program is able to determine the
problem of the defective television. ComPair can gather
diagnostic information in two ways:

• Automatic (by communication with the television):

ComPair can automatically read out the contents of the
entire error buffer. Diagnosis is done on I2C level. ComPair
can access the I2C bus of the television. ComPair can
send and receive I2C 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 I2C
busses of the TV-set.

1. First, install the ComPair Browser software (see the Quick

Reference Card for installation instructions).

2. Connect the RS232 interface cable between a free serial

(COM) port of your PC and the PC connector (marked with

'PC') of the ComPair interface.

3. Connect the mains adapter to the supply connector

(marked with 'POWER 9V DC') of the ComPair interface.

4. Switch the ComPair interface “off”.

5. Switch the television set “off” with the mains switch.

6. Connect the ComPair interface cable between the

connector on the rear side of the ComPair interface

(marked with 'I2C') and the ComPair connector at the rear

side of the TV (situated just below the tuner input, see also

chapter 4).

7. Plug the mains adapter in a mains outlet, and switch the

interface “on”. The green and red LEDs light up together.

The red LED extinguishes after approx. 1 second while the

green LED remains lit.

8. Start the ComPair program and read the 'Introduction'

chapter.

5.6 Trouble Shooting Tips

5.6.1 Scaler/TV Board Power Supply Problems

In this paragraph some troubleshooting steps for checking the
power supply of the Scaler-board and TV-board circuitry are
described.

• Measure across pin-1 and pin-4 of connector 1003
(diagram C1). +12V (13” and 15”) or +24V (20”) should be
present. If the voltage is not present, probably is caused
by:

– AC to DC adaptor is defect.
– Short circuit in TV-board (can be isolated by connector

1003).

– Fuse 1002 is open circuit.

• Measure across C2923 (diagram A10). +3V3 should be

present. If not present, probably this is caused by:

– IC7920 is defective.
– R3925 is defective.
– The power supply circuit (diagram C1) is defective (see

Scaler-board circuit trouble shooting tips).

• Measure across C2913/C2933 (diagram A10). +8V3/+5V4
should be present respectively. If not present, probably this
is caused by:

– IC 7910/7930 regulator is defective.
– Fuse 1903 is defective.
– Switching FET 7900 is defective.
– Transistor T7901 is defective.

• Measure across C2007 (diagram C1). +5V should be

present. If not present, probably this is caused by:

– +5V grounded by the load.
– Regulator IC 7001 is defective.
– Control transistor T7003/7002 is defective.
– Scaler power control signal line (POW-CON-SCALER

coming from TV-board) is defective.

• Measure pin-4 or pin-5 of connector 1341 (diagram C5).
Pin-4 should be high (+4V7) and pin-5 also should be high
(+3V4). If one/both of the voltage is not present, probably
this is caused by:

– IC 7351 (Farouja_s2300) is defective.
– Inverter board is defective.

5.6.2 General Problems

TV switched “off” or changed channel without any user action

Set switches off after “TV SWITCHING OFF” was displayed.
“Auto Standby” switched the set “off” because:

• There was no ident signal for more than 15 minutes.

• There was no remote control signal received or local key

pressed for > 2 hours.

See chapter 8 for a description on the options to enable/disable
“Auto Standby”.

5.6.3 Picture problems

Picture too dark or too bright

• Press “Smart Picture” button on the remote control. In case
the picture improves, increase / decrease the brightness
value or increase / decrease the contrast value. The new
“Personal Preference” value is automatically stored after 3
minutes.

• After switching on the Customer Service Mode the picture
is OK. Increase / decrease the brightness value or increase
/ decrease the contrast value. The new “Personal
Preference” value is automatically stored after 3 minutes.

Snowy picture

Check the “NOT TUNED” section of the Customer Service
Mode screen.

Snowy picture and/or unstable picture

A scrambled or decoded signal is received.

Black and white picture

• Press “Smart Picture” button on the remote control. In case
picture improves, increase the colour value. The new
“Personal Preference” value is automatically stored after 3
minutes.

• After switching on the Customer Service Mode the picture
is OK. Increase the colour value. The new “Personal
Preference” value is automatically stored after 3 minutes.

Menu text not sharp enough

• Press “Smart Picture” button on the remote control. In case
the picture improves, decrease the contrast value. The new
“Personal Preference” value is automatically stored after 3
minutes.

• After switching on the Customer Service Mode the picture
is OK. Decrease the contrast value. The new “Personal
Preference” value is automatically stored after 3 minutes.

5.6.4 Sound problems

No sound or sound too loud (after channel change / switching on)

After switching on the Customer Service Mode the volume is
OK. Increase / decrease the volume level. The new “Personal
Preference” value is automatically stored after 3 minutes.

5.6.5 Extra information/tips:

• Complaints that may be caused by an incorrect system
setting:

– No colours
– Colours not correct
– Unstable picture
– Noise in picture To change the system setting of a

preset:

1. Press the “MENU” button on the remote control

2. Select the INSTALL sub menu

3. Select the MANUAL STORE sub menu

4. Select and change the SYSTEM setting until

picture and sound are correct

5. Select the STORE menu item

• The Scaler is the driving engine of the LCD panel. When

there is no display and OSD on screen, check whether
sound is producible on TV channel. If sound is audible,
most likely the defective lies in Scaler board or inverter
board.

Service Modes, Error Messages, and Repair Tips

• To know fast whether inverter is functioning, visually check
if the backlights are “on” by looking at the back of the LCD
panel. Some bright spots can be seen on the side. Other
way to tell whether the backlight is working is to switch the
set to AV mode. The front of the screen had some kind of
“fogged” effect.
Note: when one of the backlight connectors has loosened,
the inverter circuit will be shut down.

• If the supply to the LCD panel is OK (likewise for backlight
supply), but no data signals (example: signals on
connector 1506) supplied from Scaler to LCD panel, you
will notice that the LCD screen will shown full screen in
sequential of BLUE, GREEN, RED, BLANK, dark-GREY,
light-GREY and WHITE repeatedly. It means LCD panel is
in good condition. The fault lies in the Scaler board

Circuit Descriptions, Abbreviation List, and IC Data Sheets

The PLL tuner UR1316 (with FM radio) delivers the IF-signal,
via audio & video SAW-filters, to the multi-system TV processor
TDA888x (item 7301, also called BOCMA). This IC has the
following functions:

• Multi-system decoder.

• Video source- and record select.

• Colour decoder.

• RGB output.

• Sound demodulator.

• Geometry control.

• Picture improvement.

• Synchronisation.

The BOCMA has one input for the internal CVBS signal and
two inputs for external CVBS or Y signals. It has only one
chroma input so that it is not possible to apply two separate Y/
C inputs. The selection is made via the I2C-bus.
It has two independently switch able CVBS outputs for e.g.
TXT, Comb-filter, CVBS-monitor, or PIP (optional).
Two SCART-connectors 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 CVBS­out on pin 19 can be used for WYSIWYR (What You See Is
What You Record).
Internal video processing is done with YUV-signals. It also
handles the video control, geometry part, and the insertion of
the TXT/OSD RGB-signals. The video part delivers the RGB
signals to the Scaler panel.

The Scaler board can receive two video input signals: SDTV
(from BOCMA) or HD (from external HD source like DVD).
The SDTV and HD signals are first digitalised, after which they
enter the Fli2300. This component does de-interlacing, scaling,
and video processing.
After the video processing, the digital data is send via a Low
Voltage Differential Signalling bus to the LCD panel. LVDS is
used to improve data speed and to reduce EMI significantly.

The microprocessor, called Painter (SAA55XX, IC7064), takes
care of the set control, error generation and analogue TXT/
OSD input- and output processing.
The Painter, ROM, and RAM are supplied with 3.3 V, which is
also present during STANDBY.
The NVM (Non Volatile Memory) is used to store the settings,
the flash-RAM contains the set software and the DRAM
(located inside the microprocessor) is capable for storing 10
Teletext pages.

The sound part is built up around the MSP34xx (Multi-channel
Sound Processor) for IF sound detection, sound control and
source selection. Dolby decoding is also done by the MSP.
Amplification is done via an integrated power amplifier IC
(AN7522 for 13” and 15” models, AN5277 for 20” models).

Power supply input is a DC voltage coming from an external
power adapter.

9.3.1 External Power Adapter

The power source for the LC13 is an external AC/DC adapter
(not repairable). The type and power of this adapter depends
on the screen size of the LCD panel and the rated audio output
power. For the 13” and 15” versions, the same 12 V_dc adapter
is used. However, the 20” model uses an adapter with 24 V_dc
output.

Specifications for 13” and 15” models:

Power : 12 V / 5 A
Type number : SA165A-1250V-3
Supplier : Sino American
Ordering code : 3139 128 76811

Specifications for 20” models:

For the internal power distribution, the following regulators are
used:

• Low power supply regulator LM2596T-5: working
frequency 150 kHz, switch current 3 A, max. input voltage
40 V, max. output voltage 5 V.

• Low power supply regulator MC34063A: working
frequency 24 - 42 kHz, switch current 1.5 A, max. input
voltage 40 V.

The supply voltages for the TV board are derived via three
MC34063A voltage regulators.

Standby: The STANDBY line (active “low”) comes from the
microprocessor and pulls the gate of FET 7900 to ground when
activated. This will block the FET. Directly after this FET, a fuse
(1903) is located.

Power down: When the DC voltage from the external adapter
drops below a certain value, the POWER_DOWN line will
inform this to the microprocessor (active "low").

9.4 Input/Output

The I/O is divided over two parts: Rear I/O and Side I/O. The
rear has two SCART inputs, and a HD (YPbPr) 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
(CVBS_TER_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 and Easylink-Plus (P50): Y_in on pin 20 and Chroma_in
on pin 15.
Easylink is handled via pin 10 of the SCART2 (this is a bi­directional communication with the microprocessor) and
supports the next features:

• Signal quality and aspect ratio matching

• One touch play & text

• PIP

• Pre-set download

• WYSIWYR

• Automatic Standby

• Country and language installation

• System Standby

• Intelligent set top box features

• NexTView download

• Timer record control

• VCR control feature

The selection of the external I/O's is controlled by the Painter
microprocessor (pins 16 & 55) and handled via IC7401:

• SEL-MAIN-R1R2 is the selection between SCART1 (R1)
and SCART2 (R2).

• SEL-FRNT-RR selection is made between Side and Rear
I/O.

The status signals (on SCART pin 8) and Front detection are
fed to the Painter (pins 2, 4 and 6).

HD (YPbPr) in: This input is directly going to the Scaler board.
See paragraph “Video: Scaler Board”.

An (alignment free) PLL carrier regenerator with an internal
VCO demodulates the video signal. This VCO is calibrated by
means of a digital control circuit, which uses the clock
frequency of the microprocessor as a reference. The frequency
setting for the various standards is realised via the I2C-bus.
The AFC output is generated by the digital control circuit of the
IF-PLL demodulator and can be read via the I2C-bus.

The video identification circuit is used to identify the selected
CBVS or Y/C signal. The IC contains a "group delay correction"
circuit, which can be switched between the BG and a flat group
delay response characteristic. This has the advantage that in
multi-standard receivers no compromise has to be made for the
choice of the SAW filter. Also, the sound trap is integrated. The
centre frequency of the trap can be switched via the I2C-bus.
The signal is available on pin 27.

QSS sound circuit

The single reference QSS mixer is realised by a multiplier. In
this multiplier, the SIF signal is converted to the intercarrier
frequency by mixing it with the regenerated picture carrier from
the VCO. The mixer output signal is supplied to the output via
a high-pass filter for attenuation of the residual video signals.
With this system, a high performance hi-fi stereo sound
processing can be achieved.

The AM sound demodulator is realised by a multiplier. The
modulated sound IF signal is multiplied in phase with the
limited SIF signal. The demodulator output signal is supplied to
the output via a low-pass filter for attenuation of the carrier
harmonics. The AM signal is supplied to the output (pin 27) via
the volume control.

9.5 Tuner and IF

9.5.1 Tuner (diagram A3, A4, and A5)

A Philips UR13xx Tuner with second input (for FM Radio) is
used in the TV board. The SIF FM signal is decoded by the
Micronas IC.
The tuner is I2C controlled, and is capable of receiving off-air,
S- (cable) and Hyperband channels.
Tuning is done via I2C. The reference voltage on pin 9 is 7.1 V.
This voltage is derived from the +5 V via a DC/DC converter.

Video IF amplifier

The IF-filter is integrated in a SAW (Surface Acoustic Wave)
filter. One for filtering IF-video (1452, or 1453 in case of system
L/L') and one for IF-audio (1454). The type of these filters is
depending of the standard(s) that has to be received.

The output of the tuner is controlled via an IF-amplifier with
AGC-control. This is a voltage feedback from pin 7 of the
BOCMA 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.

Figure 9-3 Block diagram video processing

The video processing is completely handled by a one-chip
video processor: the TDA888x. This IC is called BOCMA
(Bimos One Chip Mid-end Architecture) and contains:

• 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.

9.6.1 Source selection

The BOCMA has an input for the internal CVBS signal and two
inputs for external CVBS or Y signals. The circuit has only one
chroma input so that it is not possible to apply two separate Y/
C inputs.
The selection of the various sources is made via the I2C-bus.
The used IC version has two independently switch able
outputs:

• The CVBS1 output (pin 54) is identical to the selected
signal that is supplied to the internal video processing
circuit and is used as source signal for the teletext decoder
(Painter). Both CVBS outputs have an amplitude of 2.0
V_pp.

• The CVBS2 output (pin 26) is fed to pin 19 of SCART2 for
WYSIWYR (What You See Is What You Record).

If the Y3/C3 signal is selected for one of the outputs, the
luminance and chrominance signals are added so that a CVBS
signal is obtained again.

9.6.2 Analogue Comb filter

After the selection of the external signals (EXT1, EXT2 or Side
I/O) is made, the Y/CVBS signal is fed to the TDA888x (pin 29)
along with the Front-end signal (pin 24). The selection between
the two is made in the BOCMA and the output (pin 26) is fed to
the (optional) 2-line comb filter (to separate the luminance from
the chroma). The comb filter output is again fed to the BOCMA
(pin 21) for further processing.
The external colour signals are also fed to the comb filter. In
SVHS mode the comb filter is bypassed and the external
signals are directly fed to the BOCMA.
Switching the comb filter is done via pen 49 of IC7301. The
"video standard" selection is done via the SYS1 and SYS2
signals from the microprocessor. If the comb filter is not used,
jumpers are present and the external Y/C signals are directly
fed to the pins 20, 21 of IC7301.
After this stage, the external RGB signals (from SCART) are
added to pins 40 - 44.

9.6.3 Histogram (YUV picture improvement) IC

The demodulated video-signal can be checked on pins 40, 45,
and 46 of IC7301 and is fed to pins 39, 47, and 48. In this path,
the Histogram IC TDA9171 can be inserted. Without this IC,
jumpers are used.
The TDA9171 can control picture improvements like: histogram
processing and blue stretch.

9.6.4 Chroma and Luminance processing

The BOCMA (IC7301-B) contains a chroma band pass and
trap circuit (including a luminance delay line and the delay for

Circuit Descriptions, Abbreviation List, and IC Data Sheets

EN 89LC13E 9.

the peaking circuit). The centre frequency of the chroma band
pass filter is switch able via the I2C-bus so that the
performance can be optimised for ‘front-end’ signals and
external CVBS signals.

9.6.5 Colour decoder

The colour decoder (demodulator) can decode PAL, NTSC,
and SECAM signals. The internal clock signals for the various
colour standards are generated by means of an internal VCO,
which uses the 12 MHz crystal (item 1330) frequency as a
reference.
Under bad-signal conditions (e.g. VCR-playback), it may occur
that the colour killer is activated although the colour PLL is still
in lock. When this killing action is not wanted it is possible to
overrule it.
The IC contains an Automatic Colour Limiting (ACL) circuit,
which is switch able via the I2C-bus, and which prevents that
over saturation occurs when signals with a high chroma-to­burst ratio are received.
The reference frequency of the colour decoder is fed to the
FSC output (pin 49) and can be used to control an external
comb filter (only for 20 inch models).
The base-band delay line is integrated. The demodulated
colour difference signals are internally supplied to the delay
line. The colour difference matrix switches automatically
between PAL/SECAM and NTSC.

9.6.6 Picture improvement features

brightness. This signal is supplied to the control circuit via
the YUV interface so that an external picture improvement
IC will also have effect on this signal.

9.6.8 Synchronisation (diagrams A4 and A5)

Horizontal Sync (H Sync)

Before the video processor IC7301 can generate horizontal
drive pulses (LINEDRIVE, pin 56), the supply voltages on both
pins 23 and 53 must be present. After the start-up command of
the Painter (via the I2C), the BOCMA starts giving horizontal
pulses.

Vertical Sync (V Sync)

The vertical saw tooth generator drives the vertical output drive
circuit. On pins 63 and 64 are two differential voltages DR+ and
DR-. For this chassis, only DR- is used. This line is called V­SYNC, and goes to the Painter microprocessor.

Composite Sync (C Sync)

On pin 57 of IC7301 the sandcastle pulse (SC) is available.
This is a 2-state pulse that is used for synchronisation of the
(optional) histogram IC (item 7403).
Together with the LINEDRIVE pulse, this signal is also used to
create the C-SYNC signal, which is used to synchronise the
Scaler board.

9.7 Video: Scaler Board

In the BOCMA, various picture improvement features have
been integrated. These features are:

• Video dependent coring in the peaking circuit. The coring
can be activated only in the low-light parts of the screen.
This effectively reduces noise while having maximum
peaking in the bright parts of the picture.

• Colour Transient Improvement (CTI). This circuit improves
the rise and fall times of the colour difference signals.

• Black-stretch. This circuit corrects the black level for
incoming video signals, which have a deviation between
the black level and the blanking, level (back porch).

• Blue-stretch. This circuit is intended to shift colour near
‘white’ with sufficient contrast values towards more blue to
obtain a brighter impression of the picture

• White-stretch. This function adapts the transfer
characteristic of the luminance amplifier in a non-linear way
dependent on the picture content. The system operates
such that maximum stretching is obtained when signals
with a low video level are received. For bright pictures, the
stretching is not active.

• Dynamic skin tone (flesh) control. This function is realised
in the YUV domain by detecting the colours near to the skin
tone. The correction angle can be controlled via the I2C­bus.

9.6.7 RGB output

The ICs have a flexible control circuit for RGB and YUV input
signals which has the following features:

• Input, which can be used for YUV or RGB, input signals
and as YUV interface. The selection of the various modes
can be realised via the I2C-bus. For the YUV input 2
different input signal conditions can be chosen It is also
possible to connect the synchronisation circuit to the
incoming Y input signal. This input signal can be controlled
on saturation, contrast, and brightness.

• The RGB-1 input which is intended for OSD/text signals
and which can be controlled on contrast and brightness. By
means of software, the insertion blanking can be switched
"on" or "off". It is also possible to convert the incoming
RGB-1 signal to a YUV signal. The resulting signal is
supplied to the YUV outputs.

• The TDA888x versions have an additional YUV or RGB
input which can be controlled on contrast, saturation, and

The Scaler Board 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 HD inputs, are also handled by this board.

This 208-pins BGA-IC creates a picture signal with double the
scan lines of a conventional interlaced picture, to create a
noticeably sharper and smoother image. It offers higher picture
resolution and eliminates virtually all motion artefacts. Even on
large screens, the progressive scan lines are barely noticeable
and it reduces picture flickering significant.

All sets contain one of ITT's Multistandard Sound Processing
ICs for sound decoding:

• MSP3410 (or 3411): Multi System (incl. NICAM) decoding
for Europe and AP (Virtual Dolby).

• MSP3421 (or 3421): BTSC decoding for NAFTA and
LATAM (Virtual Dolby).

This IC takes care of the main FM, AM and NICAM sound
decoding.
The analogue input and output sections of MSP offer wide
range of switching facilities such that it is possible to distribute
all possible source signals (internal and external) to the desired
output channels (main, headphone or SCART outputs).
All MSP versions contain digital audio processing, used for the
basic left/right stereo sound, such as bass, treble, balance,
incredible sound and spatial and source selection (SIF-signal,
EXT1 or EXT2).
In addition to that, the MSP34x1 versions are also able to
perform Virtual Dolby, a Dolby approved sound mode for
surround sound reproduction with left/right speakers only.

MSP3410G Multi-system No Europe/AP
MSP3411G Multi-system Yes Europe/AP
MSP3420G BTSC No Nafta/Latam

The above-mentioned Micronas ICs are all having four pairs (L/
R) of SCART audio inputs. The fourth input pair (AV4) is used
as audio-in (input cinches located at the Scaler board) for PC
and HD modes.

To get a constant level output if the Tuner is selected, the
SCART1 output (Tuner at any time) has to be fed back to the
input selector and selected as input for the MSP (SCART1
input).

Circuit Descriptions, Abbreviation List, and IC Data Sheets

EN 91LC13E 9.

9.8.3 Audio decoding

At the input, a choice can be made between two IF-signals; SIF
and SIFM.
The selected signal is fed to the AGC. After this, an ADC
converts the IF-signal to digital.
This digital signal can be processed by two demodulation
channels. The first one is able to handle FM and NICAM
signals. The second one can handle FM and AM signals.
Each channel contains a mixer to shift the incoming signal in
the frequency domain. This shift is determined by the value of
a DCO (Digital Controlled Oscillator).
After the down-mix, the signal is fed, via a filter, to a
discriminator. From here the AM, FM or NICAM demodulation
can be performed.
Both channels contain an 'automatic carrier mute' function,
which automatically mutes the output of the analogue section
when no carrier is detected.
After demodulation, the FM-signals are subjected to a de­emphasis operation. After that, the matrix of the stereo system
is applied.

9.8.4 Audio processing

The sound processing is completely done by the MSP34xx:

• Volume control is done by the user via the SOUND menu.

• Tone control in 'Stereo' sets is done via the BASS/

TREBLE control.

• Headphone control in 'Stereo'-sets is done via the

loudspeaker output of the MSP, no sound control possible.
In 'Virtual Dolby'-sets, the MSP has a separate Headphone
output so separate sound control is possible.

• Mute control can be done in different ways:

– System muting. System muting is implemented for

“special events” such as channel/source change event,
loss of identification signal, on/off of set, during search
and auto store/program, sound mode change. This
muting is transparent to the user. Audio output should
be muted before the above “special events” occurred,
to prevent problems such as audible plop. Muting is
done via the SOUND-ENABLE line (active "low")
connected to the amplifier-IC and coming from the
Painter.

– Headphone status mute. A headphone status is

available to detect the presence of the headphone and
mute the main speakers if the headphone is detected.
The microprocessor will read the HP-SIDE-DETECT
status.

– User muting. This is a mute option available to the

user. The user select the MUTE option on the remote
control to switched off/on the sound output to the main
loudspeaker and the subwoofer.

Automatic Volume Levelling (AVL)

One of the features of the MSP-family is AVL. If used, it limits
the big volume differences in the broadcast between e.g. news
transmissions and commercials or within a movie.
To be able to get a Dolby approval (for the Virtual Dolby sets),
the AVL feature must be switch able. Therefore, the AVL
feature is customer switch able via the menu.

9.8.5 Audio amplification (diagram A9)

Some specifications:

• 13” and 15” models: 2 x 3 W with power amplifier
AN7522N.

• 20” models: 2 x 5 W with power amplifier AN5277N.

• All models are equipped with a subwoofer output.

The audio output stage is built around IC7731, which is a
balanced amplifier, and is located on the TV board. It uses an
monolithic integrated power amplifier IC, the AN5277. The gain
of the amplifier is constant. This means that volume control has

to be done via the MSP. The supply voltage (12 or 24 V
depending on the screen size) is filtered by L5733.
The AN5277 (for 20 inch models) delivers an output of 2 x 10
W_RMS to two full range speakers. A subwoofer is not
implemented.

Headphone Amplifier

The headphone outputs are from the same audio power
amplifier. The headphone jack will disconnect the audio output
to the speakers when a headphone plug is inserted. Hence, the
speakers are muted if a headphone is connected.
Resistors (items 3750 and 3752) limit the audio output to the
HP against short circuits.

9.8.6 Audio: Lip Sync

A “lip sync” circuit with an 80 ms audio delay is added, in order
to synchronise with video delay due to the complexity of the
display processing. See table:

Table 9-2 Lip sync overview

Speaker

Input

out(delay)

AV1 AV1 (80 ms) AV1 (80 ms) RF (none) AV1 (80 ms)
AV2 AV2 (80 ms) AV2 (80 ms) RF (none) RF (none)
AV3 AV3 (80 ms) AV3 (80 ms) RF (none) AV3 (80 ms)
AV4 AV4 (80 ms) AV4 (80 ms) RF (none) AV4 (80 ms)
RF RF (80 ms) RF (80 ms) RF (80 ms) RF (80 ms)

Note: SCART out not valid for NAFTA/Latam versions.

The video delay is significant, due to memory based
processing. For instance, the “frame rate conversion” cause a
delay of two frames, while the LCD panel response also cause
a delay.

The circuit is a (16 bit) FIFO based digital delay. 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 I2S digital
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 Control

9.9.1 Painter

The microprocessor (SAA55xx, IC7064 called Painter)
provides:

• Control functions for the TV-set.

• On Screen Display (OSD).

Circuit Descriptions, Abbreviation List, and IC Data Sheets

All ICs in this part are supplied with 3V5 that is also present
during Standby. This voltage is supplied via voltage regulator
IC7920.

For stable OSD and TXT, the display is synchronised to the TV
signal processing device by way of horizontal and vertical sync
signals provided by external circuits (H-SYNC and V-SYNC).
From these signals, all display timings are derived.
The OSD/TXT RGB-outputs (46/47/48) and fast blanking (52)
are fed to the BOCMA (pins 35 - 38).

9.9.2 I2C-busses

In this chassis, two I2C-busses used:

• Hardware I2C-bus, used for all IC communication.

• Separate short bus for the Non Volatile Memory (NVM), to

avoid data corruption.

9.9.3 NVM

The Non Volatile Memory IC7066 contains all set related data
that must be kept permanently, such as:

• Software identification.

• Operational hours.

• Error-codes.

• Option codes.

• All factory alignments.

• Last Status items for the customer + a complete factory

recall.

9.9.4 Light control

A pair of light sensors, at the Front Control panel, is used to
monitor the external ambient light condition and adjust the
brightness, contrast, and any relevant video parameters of the
display.

BALANCE

CIRCUIT

This circuit is a basic DC/AC inverter for driving Cold Cathode
Fluorescent Lamps (CCFL) who are located behind the LCD
panel.

9.10.2 Control

The “On/Off circuit” delivers an input signal to turn the AC
output voltage “on” or “off”:

• ON >= 2.5 V

• OFF <= 2.0 V

This signal switches transistorQ4 "on/off", resulting in "start/
stop" of the buck converter.

9.10.3 Buck Converter

This circuit uses the Power MOSFET (item Q8) to control the
input power for the Royer circuit. It is based on the "Buck
Converter" principle. The transistor switch (Q8) is the heart of
the buck converter, and it controls the power supplied to the
load. It is controlled via a PWM controller (U1, LM339).
The LM339 controls the lamp current and brightness. Its
functions include burst mode control, PWM control, and “soft
start”.

Note: this circuit needs a minimum load, in order to work
properly.

9.10.4 Royer Circuit

This is a standard Royer structure. It transfers the DC input
signal into an AC output signal.
It is a self-resonant oscillator, where one transistor conducts
current while the opposite one does not, and vice versa. The
transformer core saturates in each half cycle, causing each
transistor to switch "on" or "off".
The energy required to operate the transistors as switches, is
supplied by the feedback windings of the transformer to the
bases of the transistors.
The resistors R19 and R20 supply the base current for Q5 and
Q6. Capacitor C10/C11 and transformer T1 define the
oscillation frequency (working frequency). For the 13” model,
the working frequency lies around 45 kHz, for the 15” model,
this is about 47 kHz.

Example: If the primary voltage is 15 V_rms, and the
transformer turn ratio is 100, the secondary voltage is about 15
* 100 = 1500 V_rms.

9.10.5 HV Circuit

The High Voltage (HV) circuit supplies the power to drive the
lamps. The output voltage () is:

HV

• 13” model: 540 V (with load), 1430 V (without load).

• 15” model: 645 V (with load), 1430 V (without load).

Note: Ensure that the backlight connectors are fully inserted, in
order to prevent high voltage arcing.

This is a separate panel (separate from LCD) for the 13” and
15” models, but is built-in in the 20” LCD panel.

9.10.6 Balance Circuit

The Balance circuit uses an LCR resonant mode, to control the
output current. It delivers the same output current, even if the
load is different.

9.10.7 Feedback Circuit

The sense voltage of the feedback circuit is set at half the 5 V
supply voltage via R15 and R17 (at pin 9 of the comparator).
The control IC compares this voltage with the output current,
and regulates the PWM drive signal.

Circuit Descriptions, Abbreviation List, and IC Data Sheets

9.10.8 Protection Circuit

The protection circuit senses the output for current and for
abnormal signal behaviour, in order to protect the inverter:

• Output current: It monitors the lamp current. If this current
is correct, the inverter will operate continuous. If the current
is incorrect, the inverter will be shut down. This means for
instance that if one lamp is not working, the inverter will go
into protection.
Note: Be sure that the lamp connectors are connected
properly.

• Abnormal signals: It monitors the signals from the PWM
and Royer stage. If anything is wrong, the protection circuit
will shutdown the inverter.
