PHILIPS 20PT123 A
LED flashes in sequence and does not start, that is, it does not work. C-2447=680pfx1kv shorted, close to the horizontal output three, and when this happens the 10k r3454 smokes and you also have to change it. Solution was replaced c2447=680pf of 1kv and r3454=10k and it was beautiful. Armando de Olimpia Eletronica EvoluSom

PHILIPS FWC505
It turned everything on, but it didn't turn on the panel or the CD drawer came out, nor did it move or remove the optical drive. Well, the panel defect, I checked that the panel was missing negative voltage (-23v), I traced it back to the power supply and discovered the 4.7r resistor r3211 was open, I replaced it, it came back, but the mechanism wasn't, I checked all the voltages, everything was ok, but one of the mechanical drivers, which was not the one in the drawer, was getting very hot, I changed it, if I'm not mistaken, a tda 7370, then I changed the other one, driver 7871, the same number, then everything was ok... I hope I helped someone... hugs R3211 de 4,7r aberto ,driver 7871 SYSTEM ELETRONICA
