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 | |
