2 kérdésem volna.
A fenti hifit javítom, és az a gondja, hogy a lézerfejet le-fől rángatja (fokusz tekercs).
A KSS240-es pick-up-on melyik a lézeráramot állító poti, mert nincs kedvem kibontani.
Ezen 3 van a szokásos 1 helyett, 1más mellett
Előre is köszi Attila
Sziasztok!
Forrasztásokat átnéztem, végfoktranzisztorok nem zárlatosak, a 0.22 Ohmos ellenállásokon 0V-ot mértem.
Van ennek a típusnak valami jellemző hibája, amitől aktiválódik a védelem?
Tápot még nem mértem, mert szétborítva nem tudom bekapcsolni (vagy mégjobban szét kellene borítanom.)
Üdv: Jácint
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
