Thanks thesteve:
Well, i forgot to mention that the last capacitor i replaced, one of the 100uf close to the cd drive, blew up on me twice. Seems i was conecting the negative side to the positive side. I dont know if the diode got damaged because of that, or if it was like that from before. Anyway, the unit has no problem playing hucards, but cant read cds and doesnt play any sound now.
Does anyone know what kind of diode i have to buy for replacement?
