Safety instructions, maintenance instruction, warnings and Notes

2. Safety instructions, maintenance instruction, warnings and Notes

2.1 Safety instructions for repairs

1. Safety regulations require that during a repair: – The set should be connected to the mains via an

isolating transformer;

– Safety components, indicated by the symbol h,

should be replaced by components identical to the original ones;

– When replacing the CRT, safety goggles must be

worn.

2. Safety regulations require that after a repair the set must be returned in its original condition. In particular attention should be paid to the following points. – As a strict precaution, we advise you to resolder the

solder joints through which the horizontal deflection current is flowing, in particular ('general repair instruction'):

• All pins of the line output transformer (LOT);

• Fly-back capacitor(s);

• S-correction capacitor(s);

• Line output transistor;

• Pins of the connector with wires to the deflection

coil;

• Other components through which the deflection current flows.

• Note:

• This resoldering is advised to prevent bad

connections due to metal fatigue in solder joints and is therefore only necessary for television sets older than 2 years.

– The wire trees and EHT cable should be routed

correctly and fixed with the mounted cable clamps.

– The insulation of the mains lead should be checked for

external damage.

– The mains lead strain relief should be checked for its

function in order to avoid touching the CRT, hot components or heat sinks.

– The electrical DC resistance between the mains plug

and the secondary side should be checked (only for sets which have a mains isolated power supply). This check can be done as follows:

• Unplug the mains cord and connect a wire between the two pins of the mains plug;

• Set the mains switch to the "on" position (keep the mains cord unplugged!);

• 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 MΩ and 12 M

• Switch off the TV and remove the wire between the two pins of the mains plug.

– The cabinet should be checked for defects to avoid

touching of any inner parts by the customer.

hhhh

2.2 Maintenance instruction

It is recommended to have a maintenance inspection carried out by a qualified service employee. The interval depends on the usage conditions: – When the set is used under normal circumstances, for

example in a living room, the recommended interval is 3 to 5 years.

– When the set is used in circumstances with higher dust,

grease or moisture levels, for example in a kitchen, the recommended interval is 1 year.

– The maintenance inspection contains the following actions:

• Execute the above mentioned 'general repair

instruction'.

• Clean the power supply and deflection circuitry on the chassis.

• Clean the picture tube panel and the neck of the picture tube.

tube.

2.4 Notes

The direct voltages and oscillograms should be measured with regard to the tuner earth (H), or hot earth (I) as this is called. The direct voltages and oscillograms shown in the diagrams are indicative and should be measured in the Service Default

Ω

Mode (see chapter 8) with a colour bar signal and stereo sound (L:3 kHz, R:1 kHz unless stated otherwise) and picture carrier at 475.25 MHz. Where necessary, the oscillograms and direct voltages are measured with (D) and without aerial signal (E). Voltages in the power supply section are measured both for normal operation (G) and in standby (F). These values are indicated by means of the appropriate symbols. The picture tube PWB has printed spark gaps. Each spark gap is connected between an electrode of the picture tube and the Aquadag coating. The semiconductors indicated in the circuit diagram and in the parts lists are completely interchangeable per position with the semiconductors in the unit, irrespective of the type indication on these semiconductors.

The EXT1 socket has audio and video inputs/outputs and RGB inputs.

The EXT2 socket has audio and video inputs/outputs and S-VHS inputs.

Video recorder (only)

Carry out the connections featured opposite. Use a good

quality euroconnector cable.

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.

Video recorder

Tips

Glossary

Poor reception

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.6)

or modify the orientation of the outside

aerial. Does your antenna enable you to

receive broadcasts in this frequency range

(UHF or VHF band)?

In the event of difficult reception (snowy

picture) switch the NR on the PICTURE

menu to ON. (p. 7).

No picture

Have you connected the aerial socket

properly? Have you chosen the right system?

(p. 6) Is the contrast or the brightness badly

adjusted ? Press

and readjust the

PICTURE menu. 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.

Peripheral equipment gives a black and

white picture

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,SEC AM, NTSC) which can be replayed

by the video recorder.

The remote control no longer works.

Check that the mode selector on the side of

the remote control is set to TV.

No sound

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. 6).

Remote control

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.

Standby

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. 8).

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 3 W).

Cleaning the set

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.

Still no results?

If your TV set breaks down, never attempt to

repair it yourself: contact your dealer's after-

sales service.

RGB Signals: These are 3 Red, Green and Blue video signals which directly drive the red, green and

blue emitters in the cathode ray tube. Using these signals provides better 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. 4) 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 ration 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.

5.1 Test points

The A10 chassis is equipped with test points in the service printing. These test points are referring to the functional blocks:

• A1-A2-A3, etc.: Test points for the audio processing circuitry [A6, C6]

• C1-C2-C3, etc.: Test points for the control circuitry [C8]

• F1-F2-F3, etc.: Test points for the frame drive and frame

output circuitry [A3]

• I1-I2-I3, etc.: Test points for the intermediate frequency circuitry [A4, C1]

• L1-L2-L3, etc.: Test points for the line drive and line output circuitry [A2]

• P1-P2-P3, etc.: Test points for the power supply [A1]

• S1, S2, S3, etc.: Test points for the synchronisation

circuitry [C1]

• V1-V2-V3, etc.: Test points for the video processing circuitry [B, C2, C3]

Measurements are performed under the following conditions: Video: colour bar signal; audio: 3kHz left, 1kHz right

5.2 Service modes and Dealer Service Tool (DST)

For easy installation and diagnosis the dealer service tool (DST) RC7150 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.

5.2.1 Installation features for the dealer

The dealer can use the RC7150 for programming the TV-set with presets. 10 Different program tables can be programmed into the DST via a GFL TV-set (downloading from the GFL to the DST; see GFL 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 (For the A10 chassis, download code 4 should be used).

5.2.2 Diagnose features for the service engineer

A10 sets can be put in the two service modes via the RC7150. These are the Service Default Mode (SDM) and the Service Alignment Mode (SAM). SDM can also be entered by short circuiting the jumpers 9261 and 9262 on the chassis with a screwdriver.

Service Default Mode (SDM)

The purpose of the SDM is: – provide a situation with predefined settings to get the same

measurements as in this manual

– start the blinking LED procedure – have the possibility to override the 5V protection

Entering the 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

– By shorting jumpers 9261 and 9262 on the monocarrier

while switching on the set By temporarily shorting jumper 9261 and 9262 when switching on the set, 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 14 ) the set will shutdown after 15 sec. For recognition of the SDM, “SDM” is displayed at the upper right side of the screen.

Note: When the mains power is switched off while the set is in 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

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

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

– 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. 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. Error 0 = No error Error 1 = X-ray protection, E/W protection and/or IBeam X-ray protection, E/W protection and/or IBeam; set is switched to protection; error code 1 is placed in the error buffer; the LED will blink 1 time (repeatedly). If this happens, isolate each circuit to determine the cause. These circuits are:

• X-Ray protection - PROTN If this protection is active, the most likely cause is the LOT. Detection via pin 3 of the BOCMA - item 7301.

• EW protection - PROT-UP If this protection is active, the causes could be one of the following;

• bad contacts of: – horizontal deflection coil – linearity coil 5417 – S-correction capacitor 2418/2419 – flyback capacitor 2414/2416 – line output stage

• short circuit of: – flyback diode 6414 – EW transformer (bridge coil) 5478/5479 or 5474/5475/

5476 (version dependent)

– EW driver 7470

• High beam current protection - IBeam

As the name implies, the cause of this protection is a too high beam current (bright screen with flyback lines). Check whether the +200V supply to the CRT panel is present. If the voltage is present, the most like cause is the CRT panel or the picture tube. Disconnect the CRT panel to determine the cause. If the +200V voltage is not present, check R3840 at CRT-panel and R3445 & D6445 at main panel. Error 2 = Vertical protection - VFB If this protection is active, the cause could be one of the following (most likely in the vertical output stage):

– 7501 is faulty – poor contact or open circuit of deflection coil – +13V-VERT and/or -13V not present

Error 3 = Reserved 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 I

C 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 I

C communication):

• Main Tuner 1125 on main panel

• ITT sound processor MSP34xx ( 7064 ) on the SSB

The following tips are useful to isolate the problem area after overriding the +5V protection. Determine whether:

1. The +5V source is working properly; isolate coil 5430 and

jumper 9044 and measure the +5V

2. ITT sound processor circuit is loading the +5V; isolate coil

5430

3. The tuner is loading the +5V source; isolate jumper 9044

4. Main tuner circuit is loading the +5V source; isolate coil

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 number of

times, equal to the value of the error code. When the SDM is entered, the LED will blink the contents of the error-buffer. Error-codes ≥ 10 are shown as followed. A long blink of 750 msec. which is an indication of the decimal digit, followed by a pause of 1500 msec. 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

• after entering SDM: 1 long blink of 750 msec. + pause of

1500 msec + 2 short blinks - pause of 3 sec. - 9 short

blinks - pause of 3 sec. - 6 short blinks - pause of 3 sec. -

long blink of 3 sec. -- etc. NOTE: If errors 1, 2 or 4 occurs the LED ALWAYS blinks the last occurred error, even if the set in NOT in service mode.

5.5 TROUBLE SHOOTING TIPS

In this paragraph some trouble shooting tips for the deflection and power supply circuitry are described. For detailed diagnostics, check the fault finding tree.

5.5.1 THE DEFLECTION CIRCUIT:

– Measure if the VBAT (140V) is present across 2939/2940

(A1 POWER SUPPLY). If the voltage is not present,

disconnect jumper 9936 and 9937 ( see A1 Power Supply)

The whole Line Deflection stage is now disconnected. If the

voltage is present then the problem might be caused by the

deflection circuit. Possibilities:

– Transistor 7410 is defective

– The driver circuit around transistor 7481 is faulty

– No horizontal drive signal coming from the BOCMA IC

7301 pin 56 on the SSB

1. Note: If the C and E of 7410 are shorted, hick-up noise can

be heard from the power supply circuit.

2. To determine whether the fault is present in the line

deflection circuit (A2 LINE DEFLECTION) or in the EW

circuit/panel (screen size above 21”), insert jumper into

position numbers 9409 (in this case the EW protection is

disabled). If the basic deflection is working (picture is

parabolic distorted), then the fault is located in the EW

circuit/panel. If there is no hor. deflection, the fault is

present in the basic deflection circuitry.

3. Also take note of protection circuits in the line output stage.

If any of these circuits are activated, the set will shut down.

Depending on protections, the LED will blink according to

the fault defined. In order to determine which protection

circuit is active, isolation of circuits is necessary. These

protection circuits are:

4. High beam protection. See error 1 - IBeam.

5. X-ray protection : See error 1 If the high beam protection or the X-ray protection is active, it will switch the set to protection and the SDM is activated. The service LED blinks repetitively 1 time. If this happen, isolate each circuit to determine the cause

problem might be caused on the primary side of the switching supply. Check the output of the bridge diodes on the cathode side of D6912/D6913 or D6915 - pin 1 for approximately 300V DC. If this voltage is missing, check the bridge diodes and the fuse. If fuse F1900 is found open, check IC7921 (circuit A1) between pins 3 and 2 to make sure that there is no short circuit present. If the 300V DC is present on pin 3 of IC7902, check for a startup voltage of 16V on pin 4 of IC7921. If startup voltage is not present, check if R3914 is open; a short circuit between pin 4 and 5 will also cause this problem. It is necessary to have a feedback signal from the hot secondary side of switch mode transformer T5912 at pin 8 and pin 9 for the power supply to oscillate. If this startup voltage is present on pin 4 of IC7902 and the supply is not oscillating, check R3929 and D6929. The A10 power supply has been designed with Over Voltage Protection (OVP). To determined whether OVP is active, check whether VBAT - 141V is present at IC7971 pin 1. If not, check the components D6938, C2939 and C2940 and L5941. If these components are O.K., then check voltage at pin 3 of IC 7942. If this voltage is not present check fuse 1941 and fuse 1942. Replace if necessary. If dc-voltage is present at pin 3, replace opto-coupler 7929. Another way to confirm whether OVP is active, is to measure the voltage with an oscilloscope at IC7902 pin 4. If the voltage is fluctuating between 11-14V, then check the components as described in the above mentioned paragraph.

5.6 Customer Service Mode (CSM)

All A10.0 sets are equipped with the “Customer Service Mode” (CSM). CSM is a special service mode that can be activated and deactivated by the customer, upon request of the service technician/dealer during a telephone conversation in order to identify the status of the set. This CSM is a 'read only' mode, therefore modifications in this mode are not possible.

5.6.1 Entering the Customer Service Mode.

The Customer Service Mode can be switched on: – by pressing simultaneously the Cbutton (MUTE) on the

remote control and any key on the control buttons (P+, P-, VOL +, VOL -) on the TV for at least 4 seconds.

When the CSM is activated:

• picture and sound settings are set to nominal levels

• modes that interfere with the behaviour of the set are

switched off (sleep timer, auto standby, etc.)

5.6.2 Exit the Customer Service Mode.

The Customer Service Mode will be switched off after:

– pressing any key on the remote control handset (except

“P+” or “P-”)

– switching off the TV set with the mains switch.

All settings that were changed at activation of CSM are set back to the initial values

5.6.3 The Customer Service Mode information screen

After switching on the Customer Service Mode the following screen will appear.

5.5.2 THE POWER SUPPLY.

To trouble shoot the A10 SMPS, first check the +5V_STBY voltage on IC7968, pin 3/4. If this voltage is not present, check fuse 1961 and D6961. If 1906 or D6917 is not open circuit, the
