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

Sziasztok!
Vaz egy SONY hifitorony tipusa:HCD-R550. Az a jelenség,hogy ha bekapcsolom,PUSH-POWER-PROTECT-felirat villog a kijelzőn! Valamit matattak a hanfalkábeleknél kint,lehet összezárták! Talán végfokos lenne? és ezt jelzi ez a kiirás? Stk 407-090 van benne.lekötöttem a végfok összes lábát,és akkor is ez a felirat van jelen! Valmi tipp aki már csinált ilyent??
Köszi!
Üdv:Sparco
Sziasztok!
Valamely sony hifihez tartozó SUB ládába megszakadt a hangszóró.
SS WG-990 a hangfal típusa. Sajnos egy nap alatt sem sikerült szétszedni.
Ha valakinek volt már dolga ilyennel megköszönném a segítséget.
(A HiFi típusa azt hiszem HCV RG-440)
Hol érdemes ilyet megpróbálni beszerezni? Ez egy 10K-100K-100K motoros potméter - valószínű ALPS gyártmányú. Honnan lehet kideríteni az eredeti típust vagy helyettesítő típust?
