PHILIPS Repair Guide: Common Issues and Fixes
| Brand | Model | Fault | Detailed Problem | Solution | By |
|---|---|---|---|---|---|
| PHILIPS | 29PT4635 | Burning the horizontal outlet | Resolved after changing the output and the c2455, we found that the c 2455 47mf was ok in the test, but with an oscillograph it showed a big difference in the waveform between its two ends, we changed it and solved the defect. | bf.colatino | |
| PHILIPS | 14PT3131 | Does not turn on normal power supply | Chap. smd connected to the rear emitter. smd 7423 short | ELETROCLAUDIO AGUAS BELAS | |
| PHILIPS | 14PT3131 | Doesn't start | Chap. smd connected to the rear emitter. smd 7423 hundred short | ELETROCLAUDIO AGUAS BELAS | |
| PHILIPS | 29PT554A | TV does not turn on, when it is turned on, the stand by LED flashes and does not turn on. | 100uf/25v electrolytic capacitor, c2540 at the power supply with little capacitance. | Replace capacitor c2540 | AFONSO SANTANA |
| PHILIPS | 20GL1045 GR1 VA | No picture, normal sound | Diode d6515 with leakage, sand castle signal | ZAPELETRONICA | |
| PHILIPS | 29PT8457 L07.1L | It works normally, but after a while of operation, if you turn it off, it won't turn on again. | Stand by power supply does not fire | C 2634- d6531 replace | paulo eletronica |
| PHILIPS | 20PT4331 | No audio or delay for audio to appear | Cap. c2444 | Replace | ELETROCLAUDIO AGUAS BELAS |
| PHILIPS | 21PT9467 | Darkening the image turning bluish | Q09 | This email address is being protected from spambots. You need JavaScript enabled to view it., jaicós PI | |
| PHILIPS | FWM570/19 | Device does not work or stops working after remaining in standby. | This problem may be caused by a possible short in transistor 7902, in this case, in addition to changing the transistor, the following items must be replaced: position 5930 from 100uh to 100r and position 3916 from 2k2 to 22k | ||
| PHILIPS | FWM143/55 | Don't open the CD drawer | Cold solder on the display board at the foot of the motor cable has 1 transistor to resolder it | ELETROCLAUDIO AGUAS BELAS | |
| PHILIPS | 20GL1343 | Does not turn on...the ic tda8360, the horizontal square waveform from pin 37 of the ic 7200 does not come out, to excite the horizontal output...with 70 volts normal from the power supply... | Does not turn on, open resistor | Replacing the resistor r 3501 22k | house eletronica ltda |
| PHILIPS | 21PT6456 L03.1LAA | No audio on the channels, but in av tsound is audio, when changing channels only the word mono (character) appeared, and without audio..stereo did not appear..sap.. | No audio channel...open resistor r 3201 | Resistor r 3201, open, located on pin 31 of ic 7200...tda9370.. | house eletronica ltda |
| PHILIPS | 20PT3331 | Vertical closed 3 fingers bottom of the screen | Change transistors smd 7461 7462 do not measure | fabiusmax | |
| PHILIPS | 21PT5433 | Vertical closed at the top | Capacitor 2460 ( 82n) | stiltec | |
| PHILIPS | 21PT6456 | It turns on and off immediately, but no image, dark screen.. | Diode d 6681, with leakage...so the voltage at pin 50 of the ic7200 remains at 5v, blocking the video signal and not coming out. | Replace of the same .d 6681 .. | house eletronica |
| PHILIPS | 20PT4331 | Connects with the channel number and not the image, when enlarging the screen it is detected vertically closed at the bottom | Eprom memory | Rewrite memory | Eletroademar |
| PHILIPS | 29PT4631 | It doesn't turn on, it makes a strong hiss, and the LED goes off and on as if it were working, but not on high | 7605 transistor, photocoupler and tea1620 | The 7605 bc627 transistor was found to be broken, as a result, the device turned on but the hiss persisted. Then the +bs of the power supply was found to be low on the 6535 and 6536 diodes practically doubled, so it was just a matter of replacing the tea1620 and photocoupler and moving on. | Eletroademar |
| PHILIPS | L9.2E AA L9.2E AA | No image | Dark screen - no image or progressive active on dvd = - check resistor 3347 (open) and diode 6343 (8v2 zener) changed, when this occurs the led blinks 12x and increasing g2 the return lines appear, the sound appears normal, measure blk (approx. 4v) if not replace the diode | Check resistor 3404 | alacyte |
| PHILIPS | 14PT3131 | Turning off immediately after turning on | R3334 changed, q7494 burned and c2493 shorted | Adjust the screen too | This email address is being protected from spambots. You need JavaScript enabled to view it., jaicós PI |
| PHILIPS | 29PT4635/78 | Normal weave, but vertical, closed in half, looking like glasses with rounded lenses | Deflector | Djalma de Oliveira This email address is being protected from spambots. You need JavaScript enabled to view it. |
