Safety Instructions, Warnings, and Notes

2. Safety Instructions, Warnings, and Notes

EN 5LC03E 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

Connecting peripheral equipment

Depending on the version the TV is equipped with one or two EXT1 and EXT2 sockets.

A special adaptor is supplied to connect to EXT1 and can route the leads to the back.

The EXT1 socket has audio, CVBS/RGB inputs and audio, CVBS outputs.

The EXT2 socket (if available) has audio, CVBS/S-VHS inputs and audio, CVBS outputs.

Video recorder (or DVD recorder)

Carry out the connections shown opposite, using a good

quality euroconnector cable. If your video recorder has the

Easylink function, use the EXT2 socket.

If your video recorder does not have a euroconnector socket, the

only connection possible is via the aerial cable.You will therefore

need to tune in your video recorder's test signal and assign it

programme number 0 (refer to manual store, p. 6).

To reproduce the video recorder picture,press

Video recorder with decoder

Connect the decoder to the second euroconnector socket of

the video recorder.You will then be able to record scrambled

transmissions.

EasyLink: Digital link between the set and the video recorder which allows a direct transfer of

certain information such as channel setting or programming.

PIP (Picture in Picture):Superimposed window that displays a small picture in the main picture.

In PC mode you can display an image from the TV or other appliance (e.g. DVD or video recorder)

in a small window.

RGB signals : These are the three video signals, Red Green Blue, which make up the picture.

Using these signals improves picture quality.

S-VHS signals : These are 2 separate Y/C video signals from the S-VHS and Hi-8 recording standards.

The luminance signals Y (black and white) and chrominance signals C (colour) are recorded

separately on the tape.This provides better picture quality than with standard video (VHS and 8

mm) where the Y/C signals are combined to provide only one video signal.

NICAM sound : Process by which digital sound can be transmitted.

System : Television pictures are not broadcast in the same way in all countries.There are different

standards: BG, DK,I, and L L’.The SYSTEM setting (p. 6) is used to select these different standards.

This is not to be confused with PAL or SECAM colour coding.Pal is used in the majority of

European countries, Secam in France, the CIS and the majority of African countries.

The United States and Japan use a different system called NTSC.The inputs EXT1 and EXT2 are

used to read NTSC coded recordings.

16:9 : Refers to the ratio between the length and height of the screen.

Wide screen televisions have a ration of 16/9,conventional screen TV sets have a ration of 4/3.

Remote control

Standby

Cleaning the set

Still no results?

The proximity of mountains or high buildings may be responsible for ghost

pictures, echoing or shadows. In this case,try manually adjusting your picture: see

"fine tuning" (p.7) or modify the orientation of the outside aerial. Does your

antenna enable you to receive broadcasts in this frequency range (UHF or VHF

band)?

Have you connected the aerial socket properly? Have you chosen the right

system? (p. 7). Poorly connected euroconnector cables or aerial sockets are often

the cause of picture or sound problems (sometimes the connectors can become

half disconnected if the TV set is moved or turned). Check all connections.

You have not selected the right socket with the

key:S-VHS2 instead of EXT2.

To play a video cassette, check that it has been recorded under the same

standard (PAL,SECAM, NTSC) which can be replayed by the video recorder.

If on certain channels you receive a picture but no sound,this means that you do not have

the correct TV system. Modify the SYSTEM setting (p. 7).

The amplifier connected to the TV does not deliver any sound? Check that you

have not confused the audio output with the audio input.

Check that you have configured the computer on a compatible display resolution

(see p. 15).

You can’t get the radio sound in PC mode? When PIP is active the sound is

forced to TV. You must de-activate PIP, go into radio mode and then come back

to PC mode.

The TV set does not react to the remote control; the indicator on the set no

longer flashes when you use the remote control? Replace the batteries.

When you switch the TV set on it remains in standby mode and the indication

LOCKED is displayed when you use the keys on the TV set?

The CHILD LOCK

function is switched on (p.10).

If the set receives no signal for 15 mins,it automatically goes into standby mode.

To save power, your set is fitted with components that give it a very low power

consumption when in standby mode (less than 1 W).

Only use a clean, soft and lint-free cloth to clean the screen and the casing of your

set. Do not use alcohol-based or solvent-based products.

Disconnect the mains plug of the TV for 30 seconds then reconnect it.

If your TV set breaks down, never attempt to repair it yourself: contact your

dealer's after-sales service.

2. Service Modes

3. Errors

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, although this remote is not for sale anymore. The set can be put in two service modes via the DST (RC7150). These are the Service Default Mode (SDM) and the Service Alignment Mode (SAM).

Installation Features Dealer

For easy installation and diagnosis the DST 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.

The SDM sets the following pre-defined conditions:

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

• NTSC sets: tuning at channel 3 (61.25 MHz).

• 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.

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

CL 36532023_086.eps

Service Modes, Error Messages, and Repair Tips

EN 23LC03E 5.

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.

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 cause 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.

EN 24 LC03E5.

Service Modes, Error Messages, and Repair Tips

Protection errors:

• Error 21 = JagASM processor test failure (IC7402, diagram C4). During start-up of set, the Scaler will do a quick test by writing data to selective addresses and reading back the data. If the core supply voltage is too low or data line is broken, this error protection will be activated. Under these circumstances, check:

– Core supply of 2V5 to VDD pins of JagASM IC. – Clock pulse present at pin 3 of OSC generator item

1401 (diagram C4).

• Error 22 = Video formatter/converter I2C error IC7351 (GENESIS FLI2300, diagram C9).

• Error 23 = Video decoder I2C error IC7302 (Philips SAA7118E, diagram C3). Note: BGA IC fixed with a heat sink (see chapter 4 how to remove).

• Error 25 = NVM I2C error (diagram C8). NV memory (EEPROM - IC7752) does not respond to Scaler micro controller.

• Error 27 = SRAM IC MT48LC2M32B2TG test failure (IC7471, diagram C6).

• Error 28 = SRAM IC MT48LC2M32B2TG test failure (IC7472, diagram C6).

Non-Protection errors:

• Error 24 = HDTV decoder I2C error IC7252 (AD9883, diagram C10). Note: This error is NOT applicable to Europe execution.

• Error 29 = TV uP IC7064 (diagram A1) and Scaler uP IC7753 (diagram C8) I2C communication failure. When this error occurred, there is no display on screen. In order to read this error code, either activate SDM or press “062501” to read out the error code by blinking LED. Alternatively, read the error codes out by using ComPair.

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.

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 (Dealer Service Tool), 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.

• 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 show 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

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 inside the TV (the ComPair connector (pos.nr.1111) is situated close to the tuner on the TV Board, see Chassis Overview in chapter 1).

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 (15” and 17”) or +24V (23”) 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 R3017 or R3085 (diagram A1) with oscilloscope. There should be I2C activity. If no activity is present, this probably is caused by:

– IC 7064 micro-P is defective. – The I2C clock line or data line is grounded. (LED

should blink indicating SW protection is active).

– The IC 7064 reset circuit consisting of T7063, T7067

and T7069 and its surrounding components are defective.

• Measure pin-19 of connector 1010 (diagram A1). The standby signal should be high (2V9). If not high, probably this is caused by:

– IC 7064 micro-P is defective (output port pin-13). – Transistor 7062 is defective.

• 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 1402 (diagram C4). 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 7402 (JagASM) is defective. – Transistor 7403 is defective. – Inverter board is defective.

• Measure pin-4 or pin-5 of connector 1402 (diagram C4).

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 7402 (JagASM) is defective. – Transistor T7403 is defective. – Inverter board is loading either of the voltage.

Service Modes, Error Messages, and Repair Tips

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.

5. Select the STORE menu item

• When the set is in PC mode and there is no VGA signal

present at PC-in connector, the set will shutdown to standby in couple of seconds after showing “NO VIDEO INPUT”. This is a normal behaviour of the set to safe power.

• 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.

• 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

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
