Sziasztok!
Az erősítő problémája a következő:
bekapcsolás után a hangszórók működése szinte véletlenszerű.
Hol sub+front hol front+ rear stb...
A kolléga aki rámsózta hangprocira gyanakszik,de ezt állítólag a gyártó
csak szakszervíznek adja ki.Szerintem más hjiba lehet..
Ötlet?
előre is kösz

Hello, I got a problem with my Sony Receiver STR-DE 225.
There´s a sudden interruption of Audio in non defined intervalls - may be once ore 6 times during appr. 5hrs operation.
Interruption does not depend on Volume. Connection cables and speakers I´ve checked.
There´s a loud crack in both speakers, display shows for short time "PROTECTION".
After switching off and on again, everything operates normal until next interruption.
I removed from the inside of the receiver a lot of dust with a vacuum cleaner, but this didn´t help.
Unfortunately Sony has no documents for this device, as it is To "old" (1996), or could give me a hint,
in what cases "PROTECTION" might appear.
Is there anyone to give me a clue? Thanks

A STDBY-LED a bekapcsolás kb. 3 mp után kialszik.A STDBY-LED-R bekapcsolás után a 0 V feszültség ugyan annyi idő alatt 3,3 V ra ugrik, akkor a Q623 RT1P441C-TP-1 led drive nem tud működni. Az EVER+3.3V és az EVER 4V mindig mérhető. A készülék szervíz kézikönyve elérhető a Fórum oldalain.
I found that VC1 0n IC11 is missing. After checking I found C25(330u 35V) s/c i.e. defect. The problem solved.
