#1 Amplituner Onkyo TX-SR501E brak dźwięku

Witam,
Onkyo TX-SR501E
Sprzęt włącza się, wszystkie funkcje na panelu działają. Słychać załączające się przekaźniki przy przełączaniu wyjść, ale nie ma dźwięku na żadnym z kanałów.
Bezpieczniki widoczne na pierwszy rzut oka posprawdzane, żadne kondensatory nie wyglądają na spuchnięte.
Od czego zacząć diagnozę i ewentualną naprawę sprzętu? Nie mam doświadczenia w audio.

z góry dzięki za pomoc!

Zacznij od sprawdzenia napięcia na kolektorze tranzystora Q6703 powinno być 0V jeśli jest inaczej działa zabezpieczenie i masz spalony bądź spalone tranzystory końcowe
