| PHILIPS | 20PT3336/78 | TV turns on normally when it turns off it doesn't want to turn on again | Stand by transistor (7541) defective | Replace the same for another. | adriano SB |
| PHILIPS | 32PFL3404/78R TPS2. 1L LA | Sem backlight | Ic 801 uba2071at with pin 22 short circuited with pin 17 | Replace ic801 (uba2071at) | leitemarcellus |
| PHILIPS | 29PT752A/78R A8 | Dead | C-2618 (222 x 2kv) and fet-7680 (p16ne06). When changing c2618, when turning on the TV, when the image appeared it turned off as if it were a weak tube. | Swap c-2618 and fet-7680. obs. the fet is on the e61 board, east-west correction. | Tulio / Biguaçu SC This email address is being protected from spambots.

| PHILIPS | 29 PT4631 | Normal image, normal sound, with a four-finger dark bar on the left side of the screen from top to bottom and characters pulled to the left!!! | The horizontal exciter circuit of these devices is carried out by a pair of transistors 7461 (bc337-25) and 7463 (bc325-25) in complementary symmetry. Replace these two transistors even if they are measuring as good, as they always show a lack of gain. note the "dash" 25 that corresponds to the hfe of the transistors. As a precaution, also replace the capacitor c2405 between the collector and emitter of the npn 7461 (bc337-25). capacitor c2455 is also critical, due to capacitive reactance at high frequency, so replace it. also check the polarizations of the fet 7400. | Perse | |
| PHILIPS | 29PT4631/78 | TV works normally, then the image goes out and the screen goes completely black. | I replaced the two bc 7461(337) and 7462(327) and the two capacitors 2405(220mf 25v)2455(47mf 25v) change without testing. | ELETRÔNICA MELO BOA VIAGEM-CEARA | |
| PHILIPS | 21PT9467C/78 | Vertical closed, just a stripe at the top of the screen | Diodo byw36, resistor o,68rx2w e flyback bsc29-3807f | After changing it, the TV returned to normal. Note: the byw36 must replace both and observe the flyback if tsound is a high voltage leak | HIPERELETRONICA SERVICE (MARCELO MARAIAL) |
