Sony TA-F101R nem vált csatornát MEGOLDVA!

Sziasztok,
Adott ez a készülék ami olyat produkál, hogy bekapcs után halványan világít a “tuner” , de nem csinál semmit. Ha nyomva tartom akkor erősebben világít (ahogy kellene), kattan a relé is, de amint elengedem azonnal visszaesik a fény és annyi. Váltani sehova nem lehet. Átnéztem minden ledet, minden diódát, de mérve mind jó. Én az ic-re tippelek hogy az adta fel a küzdelmet. Kérem ebben a segítségetek. 

Köszönöm a segítséget. Elkók cserélve, minden átforrasztva, és megy szépen.

Sony hangfal szétszedése
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)
Sony STR-DE 225 Receiver, sudden interruption of Audio, after switching off everything is ok again
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

 
Sony CD132 MP3 fejegység, tuner IC beazonosítása (70080SB)
Sziasztok! A fenti fejegység csak keresi a rádió adókat, de nem áll meg sehol. A fotón látható (70080SB) IC beszerzési forrását, helyettesítő típusát (egyezik-e valamelyik TEA-val) és adatlapját keresem. Üdv.
