| Marca | Modelo (Chassis) | Sintoma | Causa | Solução | Por: |
|---|---|---|---|---|---|
| Philips | L6.2 21PT1653 | dead, chopper Tr s/c | R3524 22R gone high | ||
| Philips | L6.2 | noise on one channel or stereo indication on mono transmission | replace IC7353 MSP3400C (482220913099) | ||
| Philips | L6.2 | Width/ E/W dist | C2915 390nF o/c | ||
| Philips | L6.2 | Width control inop | TR7908 STP4NA40F1 s/c between gate & source | ||
| Philips | L6.2 | The set does not work anymore after switching it into the standby mode | Replace the line output transistor 7906. Also replace the line output driver transistor 7421 by type BC368-25 (use only a Philips version) The service code of BC368-25 is 933869720112. REMARKS : The cause is that the line output transistor 7906 | ||
| Philips | L6.2 | St/by light glows dimly only | fuse 1502 630mA o/c, then no field scan, 3928 1R res o/c, then bright raster due to no 160v line, R3429 2R2 fusible from LOPTx o/c | ||
| Philips | L6.2 | Sometimes loud noise out of speakers. | Check memory IC7605. | ||
| Philips | L6.2 | Sometimes hang-up of set; only teletext version ! | Change pos 7505 to BC337-40, service codenumber 4822 130 41344. See diagram A1, power supply. (pos 3500 is already 470 Ohm in L6.2) IRIS code 2 1 1 X. REMARKS : Only teletext version | ||
| Philips | L6.2 | Set totally inoperative. Squeaking sound. | Check C2915 on deflection module. | ||
| Philips | L6.2 | Set switches to STEREO during MONO transmission | Check and replace if necessary IC7221 on the Nicam module by the MSP3410-D (4822 209 15832). REMARKS : This solution will be implemented in production from week 9742 onwards. | ||
| Philips | L6.2 | Set does not start up if mainsvoltage is below 210 Volts. | Change resistor R3509 in circuit diagram A1 from 47K 0.5 W to 47K 1W. Service codenumber 47K 1 Watt: 4822 053 10473. REMARKS : iris code 1 1 1 9 | ||
| Philips | L6.2 | remote & local controls would lock up after the set had been on for 30 minutes | Change T7505 and T7500. The BC337 should be a /25 or /40 version. They are in the 5 volts supply to the uP. | ||
| Philips | L6.2 | Only standby LED on, no high tension | Check +150, this has to be around 150V. 145V is too low and then there is no 5V for the microprocessor. Check R3509 and D6501 Replace R3509 by 47k 1 Watt version (4822 053 10473) D6501 is BZX79B5V6 (4822 130 34173) | ||
| Philips | L6.2 | Only horizontal white stripe on screen. No vertical deflection. | Check T7904, T7905 and R3908 on deflection module. | ||
| Philips | L6.2 | Only horizontal line, no vertical deflection. | 1) check on 110 degr. module if 25V is present on C2916. If not present, probably D6907 is in short circuit and/or R3928 open. Change D6907 into BYV27-400 codenumber 4822 130 70055. R3928, 1 Ohm, codenr. 4822 052 11108. 2) check if R3908 does n |
