Safety instructions, Maintenance instruction, Warnings and Notes

–

Figure 3-1 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 (see fig. 3.1), should be replaced by components identical to the original ones; – when replacing the CRT, safety goggles must be worn.

3.3

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: • 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.

–

–

–

3.2

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 MW and 12 MW; • switch off the TV and remove the wire between the two pins of the mains plug.

It is recommended to have a maintenance inspection carried out by a qualified service employee. The interval depends on the usage conditions: –

2. In order to prevent damage to ICs and transistors, all highvoltage flashovers must be avoided. In order to prevent damage to the picture tube, the method shown in Fig. 3.2 should be used to discharge the picture tube. Use a highvoltage probe and a multimeter (position DC-V). Discharge until the meter reading is 0V (after approx. 30s). 3. Together with the deflection unit and any multipole unit, the flat square picture tubes used from an integrated unit. The deflection and the multipole units are set optimally at the factory. Adjustment of this unit during repair is therefore not recommended. 4. Be careful during measurements in the high-voltage section and on the picture tube. 5. Never replace modules or other components while the unit is switched on. 6. When making settings, use plastic rather than metal tools. This will prevent any short circuits and the danger of a circuit becoming unstable. 7. Wear safety goggles during replacement of the picture tube

The cabinet should be checked for defects to avoid touching of any inner parts by the customer.

Maintenance instruction

When the set is used under normal circumstances, for example in a living room, the recommended interval is 3 to 5 years.

Warnings

1. ESD 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 same potential. – Available ESD protection equipment: – anti-static table mat (large 1200x650x1.25mm) 4822 466 10953 – anti-static table mat (small 600x650x1.25mm) 4822 466 10958 – anti-static wristband 4822 395 10223 – connection box (3 press stud connections, 1 M ohm) 4822 320 11307 – extension cable (2 m, 2 M ohm; to connect wristband to connection box) 4822 320 11305 – connecting cable (3 m, 2 M ohm; to connect table mat to connection box) 4822 320 11306 – earth cable (1 M ohm; to connect any product to mat or connection box) 4822 320 11308 – complete kit ESD3 (combining all 6 prior products small table mat) 4822 310 10671 – wristband tester 4822 344 13999

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. –

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.

3.4

Notes 1. The direct voltages and oscillograms should be measured with regard to the tuner earth , or hot earth as this is called (see fig. 3.3) 2. The direct voltages and oscillograms shown in the diagrams are indicative and should be measured in the Service Default 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.

3

Safety instructions, Maintenance instruction, 3. Where necessary, the oscillograms and direct voltages are measured with and without aerial signal. Voltages in the power supply section are measured both for normal operation and in standby . These values are indicated by means of the appropriate symbols (see fig. 3.3). 4. The picture tube PWB has printed spark gaps. Each spark gap is connected between an electrode of the picture tube and the Aquadag coating. 5. 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.

5.4.5

Option abbreviation and Option status.

With above items the option statuses stored in the EEPROM can be changed.

ERROR and ERROR buffer (ERR refers to the "ERROR BUFFER")

This is necessary if the EEPROM is replaced by a fresh EEPROM, because a fresh EEPROM is initial loaded with default options and statuses by the microcomputer. The options stored in the factory can differ per type and stroke number. Therefore it is necessary to load the EEPROM with the correct statuses These options with statuses are indicated on a sticker glued on the CRT. For an example of the sticker see table 6.1 (this table is valid for 21PT1663/00).

00000 represent the contents of the so called "ERROR BUFFER". This buffer consist of 5 digits. In each digit an ERROR code can be displayed. The last five errors, are stored in the EEPROM, and are shown in this buffer. An error will be added to the buffer if this error differs from the last error in the buffer. The last detected error is displayed on the most left digit.

Table 6.1 Example: Suppose the display shows: 3 4 1 3 1. This means the last found error is error code 3; the last found error but one is error code 4, etc. Remark: The ERROR BUFFER is erased when the set is switched from SDM or SAM in stand by , or via code 99 via DST.(Dealer service Tool).

Primary current (I-prim) sensing (pin 7 of IC7520) The current sense voltage Vpin 7 is a measure for the I-prim through FET 7518. The I-prim is converted into a voltage by R3518. The current sense voltage Vpin 7 is used to control both the secondary output voltages and the maximum I-prim.

For a quick overall view of all diagrams see the block diagram on sheet 4. This chassis is executed with:

9.1

Power supply (Diagram A1)

9.1.1

Mains input and degaussing

The voltage across winding 1 - 2 has the same polarity as the voltage across the secondary windings. As a result the voltage across this winding is negative during the FET is conducting, and positive during the FET is not conducting. The so called demagnetization "DEMAG" function in IC7520 (input pin 8) is used for blocking the output Vpin3 during the time that there is still energy in the transformer (Isec not zero). This is realized by delaying the switch "on" point of the FET until the demagnetization is completely finished.

9.1.7 The mains voltage is filtered by L5500, L5501 and L5502, full wave rectified by a diode bridge (6502-6505) and smoothed by C2508. The DC voltage for the SMPS is applied at pin 7 of T5545 (e.g. 300V DC for 220V AC mains).

In normal operation mode the internal oscillator is adjusted at 70 kHz. This frequency is determined by C2531 and R3537 connected to pin 10 and pin 16 respectively of the IC7520. In standby mode the internal oscillator is adjusted at 20 KHz. This frequency is determined by R3536 connected to pin 15 IC7520.

Switched mode power supply The switched mode power supply (SMPS) is mains isolated. The control device IC7520 (MC44603AP) delivers duty cycle controlled pulses for driving switching FET 7518. The pulses have a fixed frequency of 70 kHz in normal operation.

9.1.8

Start up and take over circuitry. 9.1.9 Via the start-up circuitry R3530 and R3529 one side of the 220V AC mains is used to start-up IC7520 via the supply pin (Vpin 1). As long as Vpin 1 has not reached 14V5, IC7520 does not start up and only sinks 0.3mA. As soon as Vpin 1 reaches the 14V5, IC7520 starts driving FET 7518 into conduction and pin 1 sinks a typical supply current of 17mA. This supply current can not be delivered by the start-up circuit, so a takeover circuit has to be available. If no take-over take's place, the voltage on pin 1 will decrease and IC7520 switches off . In that case the restart will start again. During start-up a voltage across winding 1 - 2 is built up. At the moment the voltage across winding 1 - 2 reaches approx. (12V, D6540 start conducting and takes over the supply voltage Vpin 1 of IC7520 (take over current is approx. 17mA).

9.1.4

FET 7518 gate regulation D6524 prevents pin 3 of IC7520 from becoming negative (this will destroy the IC) due to stray inductance in the gate part of the FET. The safety resistor R3525 limits the drive current to the gate of the FET 7518

For a detailed block diagram of IC7520 (MC44603) see Fig. 9.1.

9.1.3

Standby mode In the standby mode the load decreases under a certain threshold level. The SMPS is than switching to the so called "reduced frequency mode". The switching frequency is than reduced to 20 kHz. The minimal load threshold level is determined by R3532 connected to pin 12.

The degaussing current is applied via dual PTC resistor R3504 After switching "on" the set, the PTC is cold so low-ohmic and therefore the degaussing current is very high. During degaussing, the PTC is heated up and is getting high-ohmic, as a result the current through the PTC becomes very low.

9.1.2

Demagnetization control (pin 8 0f IC7520)

Secondary output voltages sensing (pin 14 of IC7520) Winding 1 - 2 has the same polarity as the secondary windings witch are supplying the load. During the FET is not conducting the secondary windings and winding 1-2 are positive. D6537 conducts and charges C2537; the DC level across C2537 is a reference for the secondary output voltages e.g. the +95V((VBATT). This control voltage (feedback voltage) is applied via voltage divider R3538, R3539 and potentiometer R3540 (for adjusting the +VBATT) to the error amplifier input IC7520 pin 14.

Over voltage protection of the secondary voltages After start-up is the supply voltage Vpin 1 taken over by positive winding 1 - 2, and so after start up Vpin 1 is a measuring point for the secondary output voltages. After start-up (via an internal switch) this Vpin 1 is internally tapped (voltage divided) to a voltage which can be measured at pin 6 (so Vpin 6 is also a measuring point for the secondary output voltages). As soon as the voltage Vpin 6 > 2V5 the logic in IC 7520 will shut down the output at pin 3. This 2V5 threshold at Vpin 6 is equivalent to a Vpin1 of 16V DC which is equivalent to a voltage at the supply voltage (VBATT of approx. 95V DC (normal operation) and 102V DC (standby). After switching "off" because of over voltage protection, the IC starts up again In case an over voltage situation is sensed at the secondary output voltages, the SMPS will go in over voltage protection. In case the over voltage situation remains present, the SMPS will give over voltage protection slow-start, over voltage protection slowstart, etc. ( a very good audible hick-up mode).

9.1.10 Undervoltage protection of the secondary voltages If the supply voltage Vpin 1 < 9V DC the output pulse at pin 3 will be shut down. As soon as Vpin 1 < 7V5, the IC7520 will be totally shut "off". Vpin 1 of 9V DC is equivalent to a voltage at (VBATT of approx. 70V DC (normal operation) and 95V DC(standby). Vpin 1 of 7V5 is equivalent to a voltage at

9.1.14 DC Output Voltages Protections •

In case an under voltage situation is sensed at the secondary output voltages, the SMPS will first switch "off" the pulse and then switch "off" the complete IC 7520. • In case the IC 7520 is switched "off", the SMPS will switch "off". In case the under voltage situation remains present, the SMPS will give under voltage protection, slow-start, under-voltage protection, slow-start, etc. ( a very good audible hick-up mode).

9.1.11 Unload protection

9.2

+5V protection :When any overload for the +5V supply occurs (pin 1 of IC7541 < 6.5V) the protection circuit in IC7541 turns on. and shuts down the +5V supply. and also +8V supply. +8V protection : When any overload for the +8V supply occurs (pin 1 of IC7541 < 6.5V) the protection circuit in IC7541 turns on and shut down the output +8V supply. If the voltage on pin 7 is < 2.4V the +8V will also shut down.

Single chip TV-processor IC7225 (TDA8374) Introduction :

In case the load goes down (e.g. the line deflection goes down because of standby mode or some failure in the line deflection circuit) this is detected by IC7520 via I-prim and secondary output voltages sensing. In case the load decreases below a certain threshold the SMPS will switch in "reduced frequency mode" of 20 kHz (this threshold is determined by the voltage level at pin 12 IC7520);

In this chip most of the video, audio and sync circuits are integrated. In the diagrams the IC is split up in next 5 parts (5A,5B,5C,5D and 5E).

In case of an unload situation the set will switch to "low frequency mode" or standby mode. Whether this unload situation of the SMPS is caused by the standby command or by a failure (e.g. in the line circuit),can only be determined by switching on the set again which the remote control, in case of standby mode the TV will switch "on" again, in case of unload situation the set will not switch "on".

9.1.12 Overload (short-circuit) protection If the secondary load becomes too high, I-prim becomes too high which is sensed by the current sense voltage Vpin 7. This voltage Vpin 7 is not allowed to exceed 1V DC by IC 7520 and so gives current limiting.

9.3

Two kinds of microprocessors are used, one with and one without teletext function The (C with teletext (IC7600) is drawn in the diagram with the outer pin numbering. In case of no TXT a (C (IC7601) is used with fewer pins. This (C is drawn in the diagrams with the internal pin numbering. In case of the (C with integrated teletext function, the CVBS-TXT signal is fed to pin 23. The TXT and OSD information are combined at pins 32-3334.

As the I-prim is limited, the secondary output voltages will also drop and so supply voltage Vpin 1 will drop. As soon as Vpin 1<9V DC the driving pulse at pin 3 will stop. As a result of these 2 mechanism in case of an overload the secondary voltages will drop very fast. This is called the foldback mechanism, the fold-back point can be adjusted by pin 5 IC7520 this point is adjusted to a maximum tolerable output power of 85W at 90V AC and 165W at 276VAC.

9.4

As a result in case of short-circuit (or overload) the TV will be in a very good audible hick-up mode.

The +8V output is determined by the voltage on pin 7 of IC 7541 This voltage is adjusted via voltage divider 3552 and 3554.

The line output circuitry (see diagram A2) Pin 40 IC 7225-5D delivers the drive signal for the line output stage. Via TS7440 and TS7441 the drive signal is applied to the line output transistor 7445 and line output transformer (LOT) 5445. The line output stage supplies the line deflection current. Via secondary windings of the LOT the following supply voltages are generated:

After this fold-back, the IC starts up again. In case the overload situation remains present, the SMPS will give fold back again, slow-start, fold-back, slow-start, etc.;

General: In the set next protections are build in:

Fast discharge circuit.

9.6.4

+13V protection

TS7420 and TS7421 (see diagram A1) formed a fast discharge circuit. When the voltage on the collector of TS7421is >6V the circuit will switch off the horizontal drive immediately via pin 50 IC7225-5D (see diagram A2).

9.6.2

Protection input pin 16 of IC7600 (see diagram A4). If this pin is connected to ground, the set is switched in protection. At this pin the +13V is monitored via the circuit 7655,7608. The emitter of 7608 becomes "low" (0V7 lower than the base voltage) if the +13V drops. This will force pin 16 of the (C "low" and will switches the set in protection.

CRT flash protection. The BCI information is applied to pin 42 of IC7225-5D.(diagram A2) If due to a flash in the picture tube the voltage on pin 42 is >6V, the horizontal drive is switched off immediately. If the voltage is again <6V the horizontal drive is switched on again.

9.6.3

9.6.5

+13V and -13V protection Vertical deflection output IC7401(see diagram A2) is supplied by +13V and -13V. When the current delivered by the +13V or 13V is increasing to much will this result in a voltage drop of <6.5V.at pin 3 of the IC (VFL) . This voltage drop is applied to pin 37-IC7600 (micro computer). The micro-computer will place the set in the standby mode.

EHT over voltage protection. The BCI information is also applied to pin 50-IC7225-5D (diagram A2). First the BCI compensate vertical picture
