Safety & Maintenance Instructions, Warnings, and Notes

2. Safety & Maintenance Instructions, Warnings, and Notes

2.1 Safety Instructions For Repairs

Safety regulations require that during a repair:

• Due to the ‘hot’ parts of this chassis, the set must be connected to the AC power via an isolation transformer.

• Safety components, indicated by the symbol , should be replaced by components identical to the original ones.

• When replacing the CRT, safety goggles must be worn.

Safety regulations require that after a repair, the set must be returned in its original condition. Pay particular attention to the following points:

• General repair instruction: as a strict precaution, we advise you to re-solder the solder connections through which the horizontal deflection current is flowing, in particular:

– 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 re-soldering is advised to prevent bad connections due to metal fatigue in solder connections and is therefore only necessary for television sets more than two years old.

• Route the wire trees and EHT cable correctly and secure

them with the mounted cable clamps.

• Check the insulation of the AC power cord for external

damage.

• Check the strain relief of the AC power cord for proper

function, to prevent the cord from touching the CRT, hot components, or heat sinks.

• Check the electrical DC resistance between the AC plug

and the secondary side (only for sets that have an isolated power supply). Do this as follows:

1. Unplug the AC power cord and connect a wire between the two pins of the AC plug.

2. Turn on the main power switch (keep the AC power cord unplugged!).

3. Measure the resistance value between the pins of the AC plug and the metal shielding of the tuner or the aerial connection of the set. The reading should be between 4.5 MΩ and 12 MΩ.

4. Switch the TV OFF and remove the wire between the two pins of the AC plug.

• Check the cabinet for defects, to prevent the possibility of the customer touching any internal parts.

2.3 Warnings

• In order to prevent damage to ICs and transistors, avoid all high voltage flashovers. In order to prevent damage to the picture tube, use the method shown in Fig. 2-1, to discharge the picture tube. Use a high voltage probe and a multi-meter (position VDC). Discharge until the meter reading is 0 V (after approx. 30 s).

V

CL 26532098/042

Figure 2-1

• All ICs and many other semiconductors are susceptible to electrostatic discharges (ESD)". Careless handling during repair can reduce life drastically. When repairing, make sure that 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 potential. Available ESD protection equipment: – Complete kit ESD3 (small tablemat, wristband,

connection box, extension cable, and ground cable) 4822 310 10671.

– Wristband tester 4822 344 13999.

• Together with the deflection unit and any multi-pole unit,

flat square picture tubes form an integrated unit. The deflection and the multi-pole units are set optimally at the factory. Adjustment of this unit during repair is therefore not recommended.

• Be careful during measurements in the high voltage section and on the picture tube.

• 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.

2.4 Notes

2.2 Maintenance Instructions

It is recommended to have a maintenance inspection carried out by qualified service personnel. 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 three to five years.

• When the set is used in an environment with higher dust, grease or moisture levels, for example in a kitchen, the recommended interval is one year.

• The maintenance inspection includes the following actions:

1. Perform the 'general repair instruction' noted above.

2. Clean the power supply and deflection circuitry on the

chassis.

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

tube.

• Measure the voltages and waveforms with regard to the

chassis (= tuner) ground (,), or hot ground (-), depending on the area of circuitry being tested.

• The voltages and waveforms shown in the diagrams are indicative. Measure them in the Service Default Mode (see chapter 5) with a color bar signal and stereo sound (L: 3 kHz, R: 1 kHz unless stated otherwise) and picture carrier at 475.25 MHz (PAL) or 61.25 MHz (NTSC, channel 3).

• Where necessary, measure the waveforms and voltages with ()) and without (*) aerial signal. Measure the voltages in the power supply section both in normal operation (+) and in standby (/). These values are indicated by means of the appropriate symbols.

• The picture tube panel 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.

• All service-unfriendly modes (if present) are disabled, like: – (sleep) timer, – child/parental lock, – blue mute, – hotel/hospitality mode – auto switch-off (when no 'IDENT' video signal is

received for 15 minutes),

– skip / blank of non-favorite presets / channels, – auto store of personal presets, – auto user menu time-out.

• Operation hours counter.

• Software version.

• Option settings.

• Error buffer reading and erasing.

• Software alignments.

How to Activate SDAM

Use one of the following methods:

• Use a System 7 remote control type T374AH (RCtransmitter RG4172BK) and key in the code '062596' directly followed by the 'M' (menu) button or

• Short circuit jumper wires 9631 and 9641 on the mono carrier (see fig. 8-1) and apply AC power. Then press the power button (remove the short circuit after start-up). Caution: Entering SDAM by short circuiting wires 9631 and 9641 will override the +8V-protection. Do this only for a short period. When doing this, the service-technician must know exactly what he is doing, as it could lead to damaging the set.

After activating SDAM, the following screen is visible, with S at the upper right side for recognition.

Use one of the following methods:

• In SDAM, select menu items with the CURSOR UP/DOWN key on the remote control transmitter. The selected item will be highlighted. When not all menu items fit on the screen, move the CURSOR UP/DOWN key to display the next / previous menu items.

• With the CURSOR LEFT/RIGHT keys, it is possible to: – Activate the selected menu item. – Change the value of the selected menu item. – Activate the selected submenu.

• When you press the MENU key in a submenu, you will

return to the previous menu.

How to Store Settings

To store settings first go back to the main menu (fig. 5-1) with "MENU" button on the remote control and then leave the SDAM with the "STANDBY" button on the remote control.

How to Exit

Switch the set to STANDBY by pressing the power button on the remote control transmitter. The error buffer is cleared. (If you switch the set 'off' by removing the AC power, the set will return in SDAM when AC power is re-applied and the error buffer will not be cleared.)

5.3 Problems and Solving Tips (Related to CSM)

5.2.2 Customer Service Mode (CSM)

Purpose

When a customer is having problems with his TV-set, he can call his dealer. The service technician can then ask the customer to activate the CSM, in order to identify the status of the set. Now, the service technician can judge how severe the complaint is. In a lot of cases he can advise the customer how to solve the problem, or he can decide if it is necessary to visit the customer. The CSM is a read only mode, therefore modifications in this mode are not possible.

How to Activate

To activate the CSM press the RECALL button on the System 7 remote control RG4172BK.

After switching ON the Customer Service Mode, the following screen will appear:

5.3.1 Picture Problems

Note: Below described problems are all related to the TV

settings. The procedures to change the value (or status) of the different settings are described.

No Colours / Noise in Picture

Check CSM line 4. Wrong colour system installed. To change the setting:

1. Press the MENU button on the remote control.

2. Select the INSTALLATION sub menu.

3. Select and change the SYSTEM setting until picture and sound are correct.

4. Select the STORE menu item.

Colours Not Correct / Unstable Picture

The new 'Personal' preference value is automatically stored.

Snowy Picture

Check CSM line 5. If this line indicates 'Not Tuned', check the following:

• No or bad antenna signal. Connect a proper antenna signal.

• Antenna not connected. Connect the antenna.

• No channel / pre-set is stored at this program number. Go

to the INSTALL menu and store a proper channel at this program number.

• The tuner is faulty (in this case the CODES line will contain error number 10). Check the tuner and replace / repair if necessary.

Snowy Picture and/or Unstable Picture

• A scrambled or decoded signal is received.

Black and White Picture

Increase the COLOR value when:

• The picture improves after you have pressed the 'Smart Picture' button on the remote control.

The new 'Personal' preference value is automatically stored.

Menu Text Not Sharp Enough

Decrease the CONTRAST value when:

• The picture improves after you have pressed the 'Smart Picture' button on the remote control.

The new 'Personal' preference value is automatically stored.

5.3.2 Sound Problems

No Sound or Sound too Loud (After Channel Change / Switching On)

Increase / decrease the VOLUME level when the volume is OK after you switched on the CSM. The new 'Personal' preference value is automatically stored.

5.4 Error Buffer

The error code buffer contains all detected errors since the last time the buffer was erased. The buffer is written from left to right. When an error occurs that is not yet in the error code buffer, it is written at the left side and all other errors shift one position to the right.

5.4.1 How to Read the Error Buffer

Use one of the following methods:

• On screen via the SDAM (only if the TV gives a picture). Examples:

– ERROR: 0 0 0 0 0 : No errors detected – ERROR: 6 0 0 0 0 : Error code 6 is the last and only

detected error

– ERROR: 9 6 0 0 0 : Error code 6 was first detected and

error code 9 is the last detected (newest) error

• Via the blinking LED procedure (when you have no picture). See next paragraph.

5.4.2 How to Clear the Error Buffer

The error code buffer is cleared in the following cases:

• When you exit SDAM with the STANDBY command on the remote control (when leaving SDAM, by disconnecting the set from AC power, the error buffer is not cleared).

• If the content of the error buffer has not changed for 50 hours, it resets the buffer automatically.

Error Codes

In case of non-intermittent faults, clear the error buffer before you begin the repair. This to ensure that old error codes are no longer present. If possible, check the entire contents of the error buffer. In some situations, an error code is only the result of another error code and not the actual cause (e.g., a fault in the protection detection circuitry can also lead to a protection).

5.5 The Blinking LED Procedure

Via this procedure, you can make the contents of the error buffer visible via the front LED. This is especially useful when there is no picture. Go into the SDAM menu with one of the following methods:

1. '062596 M' on a System 7 remote control (the RCtransmitter RG4172BK).

2. Short circuit wires 9631 and 9641 on the mono carrier and apply AC power. Then press the power button (remove the short circuit after start-up).

As soon as you are in SDAM the blinking LED procedure will start.

Error-codes are shown as follows:

1. n short blinks (the number of n indicates the error code number.),

2. a pause of 1.5 s,

3. n short blinks (for the next error),

4. when all the error-codes are displayed, the sequence finishes with a LED blink of 3 s,

5. the sequence starts again.

Example of error buffer: 12 9 6 0 0 After entering SDAM:

1. 12 short blinks followed by a pause of 1.5 s,

2. 9 short blinks followed by a pause of 1.5 s,

3. 6 short blinks followed by a pause of 1.5 s,

4. 1 long blink of 3 s to finish the sequence,

5. the sequence starts again.

• Set is non-stop in hiccup mode

Set is in over current mode; check the secondary sensing (opto coupler 7515) and the 'MainSupply' voltage. Signal 'Stdby_con' must be logic low under normal operation conditions and goes to high (3.3 V) under standby and fault conditions.

• Set turns on, but without picture and sound

The screen shows snow, but OSD and other menus are okay. Blinking LED procedure indicates error 11, so problem is expected in the tuner (pos. 1000). Check presence of supply voltages. As 'Vlotaux+5V' at pin 5 and 7 are okay, 'VT_supply' at pin 9 is missing. Conclusion: resistor 3460 is defective.

• Set turns on, but with a half screen at the bottom. Sound is okay

Blinking LED (set in SDAM mode) indicates error 3. Check 'Vlotaux+13V' and '+50V'. If they are okay, problem is expected in the vertical amplifier IC7471. Measure with a scope the waveform on pin 17 of the UOC. Measure also at pin 1 of IC7471. If here the signal is missing, a defective resistor R3244 causes the problem

5.6 Protections

If a fault situation is detected an error code will be generated and if necessary, the set will be put in the protection mode. Blinking of the red LED at a frequency of 3 Hz indicates the protection mode. In some error cases, the microprocessor does not put the set in the protection mode. The error codes of the error buffer can be read via the service menu (SDAM) or the blinking LED procedure.

To get a quick diagnosis the chassis has two service modes implemented:

• The Customer Service Mode (CSM).

• The Service Default Alignment Mode (SDAM). Start-up of

the set in a predefined way and adjustment of the set via a menu and with the help of test patterns.

5.7 Repair Tips

Below some failure symptoms are given, followed by a repair tip.

• Set is dead and makes hiccuping sound

'MainSupply' is available. Hiccuping stops when desoldering L5561, meaning that problem is in the 'MainSupply' line. No output voltages at LOT, no horizontal deflection. Reason: line transistor TS7460 is defective.

• Set is dead, and makes no sound

Check power supply IC7520. Result: voltage at pins 1, 3, 4, 5 and 6 are about 180 V and pin 8 is 0 V. The reason why the voltage on these pins is so high is because the output driver (pin 6) has an open load. That is why MOSFET TS7521 is not able to switch. Reason: feedback resistor 3523 is defective.Caution: be careful measuring on the gate of TS7521; circuitry is very high ohmic and can easily be damaged! (first connect measuring equipment to ground, then to the gate).

• Set is in hiccup mode and shuts down after 8 s.

Blinking LED (set in SDAM mode) indicates error 5. As it is unlikely that P 'POR' and '+8V protection' happen at the same time, measure the '+8V'. If this voltage is missing, check transistor TS7480.
