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!
Kipukkant ebben a magnóban HA13001-es sztereo végfok IC, kölcsönadták valakinek az meghosszabbitotta, a drótok kopaszon toldva lettek es összeértek, az IC ára rettenetes nem ér az egész magnó annyit.
Legalabb egy 500 sémát atneztem hogy talaljak helyette valamit, vegul is legjobban hasonlit a HA1394 (2 EUR) ugyanazok a tápok,bemenet, kimenet meg a tok is ugyanaz. Egyedul az pin1-es lab nem testre megy hanem 100uF-en keresztul megy a testre,pin6 tesre megy.
Bekötöttem a HA1394-et es meg se nyikkan, pin3,4 bemeneten van jel, gondoltam biztos rossz az IC, IC kivesz masik mas szerias betesz ugyanaz a helyzet.
Nagyobb jelszintu jelet adtam neki akkor nagyon halkan torzitva recsentget..Tápja egyoldalas 17V, ez megfelelô, hangszórók jók.

Sziasztok!
Ehhez kellene kijelző, mert a szalagkábelről lejött a vezetőréteg, a LCD panel felől. Hol lehet beszerezni ilyet, vagy bontás is érdekelne? A szalagkábel végére ezek a számok vannak írva: 9 648 059 022MFT.
üdv: nem tudom, jó helyen van-e itt.
