PHILIPS Repair Guide: Common Issues and Fixes
| Brand | Model | Fault | Detailed Problem | Solution | By |
|---|---|---|---|---|---|
| PHILIPS | 29PT4635 | The vertical heats up and burns | The vertical one was broken, I changed it and tsound was a c25v 47uf dry capacitor, I changed it | This email address is being protected from spambots. You need JavaScript enabled to view it. | |
| PHILIPS | 20PT529 | Doesn't start | 7522 supply smd transistor | aedo | |
| PHILIPS | 21GX1669/78R GR6-AL | Dark screen with sound when opening it writes, it lightens very little, no characters appear | Replace eprom | Schulz | |
| PHILIPS | 20GL1041 | Low power supply | Replace transistor ts355 | Moraes sptv | |
| PHILIPS | 20PT529A/78R **** | Low sound at maximum volume. | Capacitor c-2883 | Replace directly without testing. | wagner |
| PHILIPS | DIVERSOS T/GL VáRIOS | Retrace lines and dark cloud-like screen at the bottom of the screen. | Clean the glue between the vertical capacitors and the chassis. They are to the left of the flyback or tsh. | Conscerta | |
| PHILIPS | 29PT4635 | With retrace lines and then turns off | Ci code. 7330 is the tda 6107jf | I found that it had a voltage of +- 200v, even so tsound were traces on the screen, just replace it! | caio |
| PHILIPS | 21PT5433 | Vertical closed at the top | Capacitor c2460 82kx100v alterado | retec | |
| PHILIPS | 20PT122A | LED blinks weakly | Low power supply | Dry electrolytic capacitor 47/160 c2551 | ECeletronica |
| PHILIPS | PV461 | The functions on the screen (channel number) kept disappearing, sometimes nothing appeared or disappeared prematurely. | S1802 | I replaced the internal capacitor of the s1802. It was perfect. | moura1 |
| PHILIPS | 21PT6456/78 L03-1LAA | After suffering a change in the electrical network which blew the varistor 3505 and the fuse, it only turned on at 110v | After changing the fuse and varistor, it was necessary to change the tea1506t (7520) to work on 220v. | 110909 | MAIRES |
| PHILIPS | 29PT4631/78R | No plot and no sound | This TV had no plot and no sound. When activating the remote control, the LED responded normally. in the on position tsound was 126v at the tsh collector. It seemed like that classic defect of this model in which you just need to replace the transistors q7461 (bc337-25) and q7463 (bc327-25) plus the capacitor 2455 (47μfx25v). I was able to observe that only the bc337 was altered, but after replacing the three components the defect did not change. in the collector of q7461 it had 11v base 0v and emitter 0.3v. I started to suspect that the q7462 (pdtc143zt) could be the cause of tsound being no voltage at the base of the q7461, but as it is an SMD that is difficult to buy anywsound, I did some more tests and the defect was the q7460 (bu4508dx) completely shorted between base and emitter. Before, I had only tested between collector and emitter (wsound the short normally occurs). As I had a bu2725dx available I put it as a replacement. in place of q7461 I put 2sd667 and in place of q7463 I put 2sb647. An interesting detail is that the q7461 heats up much more than the q7463, which is why I put a small heatsink on it. | ||

| PHILIPS | PT4640/78 L1 | Turns on/off in a few seconds | C2455,q746/q7463 e screem | Replace these components even if they are good, and lastly, if they continue to turn off by themselves, check the flay screm" due to internal oxidation causing this problem, if possible, when adjusting, mark the position and add a drop of glue so that it does not become loose | ELETRÔNICA PALAURO |
| PHILIPS | 29PT5645 | Turns on, TV with dark screen vertical lines and disarms | Shorted smd diode 6451 and capacitor 2465 10/100v | ladmyr rezende | |
| PHILIPS | 20GX | Blurry image | Change the kinescope socket | edson proesi | |
| PHILIPS | 21GX1656/78Z | TV with sound, screen off, that is, no image. | When doing the repair, I verified that the tube filament was lit, so that's when I released the screen wire from the tube plate, turned on the TV and measuring I didn't find voltage, it causes fly-back. | The fly-back= at2079/b5 was replaced and it was... ok. | Armando |
| PHILIPS | 20PT3331 | TV didn't tune in to any channel, but the AV came on normally | This TV gave me a bit of trouble but nothing that can't be resolved. The seletronic power supply tensions were all ok. I went as far as replacing it. But it didn't solve it. That's when I decided to check around the varicap. I went to the pin 4 and 5 of the seletronic and I had a surprise following the trail tsound are 2 100r smd resistors on them, they are written like this (101) because they were burnt out | I replaced spark plugs and it was file, position r smd 3003, rsm 3004. pin 4 and 5 of seletronic scl sda | heliomar |
