Postovani, dosao sam u posed pojacala koje je od samog starta imalo problem sa jednim kanalom, u smislu da se cuo tise, nekad se to pretvaralo u sum i posle nekog vremena se situacija popravljala. Sada vec dva dana na desnom kanalu se ne cuje nista. Takodje sustanje postoji i na levom ali povremeno. Ono sto sam uspeo da vidim jeste po nekim forumima da je ovo generalno cest problem sa ovim Pioneer-om.
Pominju se neke diode, ne razumem se, pa ako moze pomoc da li ovo moze da resi problem?
I was reading a thread on another forum where a member was also having trouble with his A-77X, although with noise in one channel. He was advised to check zener diodes 1-4 on the board labeled by the service manual "gwh-171" as well as two (C3 and C5) 100uf 25v electrolytic caps. Would this be well advised in my situation? It cured his issue. The diodes are only 22v half-watt parts- seems a little on the light side.
Hvala unapred.
