| PHILIPS | 29PT 5642/78 | TV buzzing fly back, TV has a strong buzzing sound on the fly back, burning resistor 3440, burning the transistor q 7406, and with overheating in the horizontal output, the screen appears closed horizontally, completely out of horizontal frequency sawtooth effect. | The fet transistor of the horizontal drive, the 7404 it works with an internal diode, the diode is shorted, the transistor is the si 2306 ds | Replace the 7404 transistor, the problem is that you can't find it to buy anywhere | Eletrônica do Ricardo |
| PHILIPS | 21PT5437 | No video just characters | Resistor r3442 (100k) aberto | This email address is being protected from spambots. You need JavaScript enabled to view it. | Bruno Nicacio |
| PHILIPS | 29PT5642 | Device inoperative, power supply does not start. | 9v1 zener diode 6573 with leakage. (almost in short circuit) | 9v1 zener diode 6573 replacement. | wagguinho |
| PHILIPS | 29PT4640 | Television inoperative (horizontal does not start) normal power supplys reacts to the remote control, but does not work. | 6462 9v1 zener diode leaking (almost short-circuited) replace it. | Replace d6462 zener diode 9v1. | wagguinho |
| PHILIPS | 32PD6932/78R | TV doesn't turn on, only the standby light comes on | Transitor 7461,7463 aberto bc337,bc327 | Gilberto | |
| PHILIPS | 21PT434A | The TV just stays on standby and when you turn it on it flashes 4 times and goes back to standby again | In this case, what I caught was simply an unusual occurrence. The TV had already been screwed by someone else and the technician's horse left a bridge connecting the horizontal driver with a clue of ours that it was hard to find out, see, just find out because I went to measure the impendances of the drive and it was going directly to all the pins | Just remove the bridge and it works fine | This email address is being protected from spambots.

| PHILIPS | PT4635/78R | Horizontal burning | After changing bc 337/25(7461), 327/25(7463), cap 2455, I changed the drive transformer (5461) and bingo! | Trafo do drive(5461) | audio e video |
| PHILIPS | 20PT3331/78R | Power supply gave a peak and went into protection, going into protection | I found a lack of 12v power supply that is generated from the flyback to the vertical output, r3445 on pin 8 of the flyback open. | Alvanyr This email address is being protected from spambots.

| PHILIPS | 21PT5433/78R | How to test the vertical | The vertical one has two transistors, they are called married one npn another pnp the collector of the npn has 20v +b the npn has 12v -b in the middle of the two transistors we have to have 0v you can measure it on the connector itself that goes to the deflector coil if one appears voltage, the vertical circuit is defective and it could be the transistors, some component around them connected to them or the IC does everything that is not providing the sawtooth etc. | Miltom eletronica micro e epron |
