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 segítségeteket szeretném kérni. Van nálam egy SONY erősítő amiben tönkrement a bemenetén lávő kapcsoló ic(LC78212). Az üzletben csak LC7822N -t tudnak beszerezni.Elméletileg ugyanaz ,de gyakorlatban helyettesíthető-e egyik a másikkal. Előre is köszönöm! drobi
Sziasztok.
Megjött az IC LC7822. Beépítettem az erősítő üzemel, csak mindegy hogy mit választok vagy hova dugom a bemeneti csatlakozót mindég ugyanaz szól. Mint ha ott sem lenne a kapcsoló ic.Ha váltok másik készülékre egy pillanatra megtorpan a hang , mint mikor normálisan üzemel a készülék ,de változás nincs.Volt-e már valakinek hasonló esete.
(Azt nem írtam le ,hogy amikor elhozták a CD bemeneten elvolt füstölve az ellenállás és a kondenzátor .Az IC pedig szét volt repedve.(Biztosan azért nem üzemelt mert kijött belőle a füst!)
Ötlet?
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)
