Sziasztok Mesterek!
Van ez a bizonyos autórádió-CD játszó.
Eredeti tápkábele megvan, eurócsatlakozó van a másik végén.
Mindent megfelelően bekötve áramfelvétel semmi, készülék nem indul.
(sajnos rajzot nem találtam hozzá itt fent)
A beépített RCA-n kívül van még egy 12 pólusú négyszögletes csatlakozó kábel is a hátlapon.
Ezt nem tudom mire való, de elvileg CD-tár vezérlés lehet.
A rádiót úgy hozták, hogy működik, valami hajóban volt előzőleg.
De nem működik!
Bizti nincs rajta sehol, sem a kábelében!
Lehet, hogy az a bizonyos kábel rejt valami titokzatos dolgot?
(van még hozzá egy kis infrás távvezérlő is, de azzal sem csinál semmit)
Esetleg ismerős ez a készülék valakinek?
Tibor
Sziasztok'
A fenti végfokhoz keresnék rajzot, vagy hogy melyik végfokhoz hasonlít a felépítése, vagy "klónja".
Sikeres végfok csere után már működik, de nem szól, mintha az input része nem menne.

I have and found most of the voltages as indicated on the circuit diagram, till op amp M 5218P; are near those specifed. The output on the centre of the two power transistors of both the channels are also alright.
While looking at the voltages on test points as mentioned on the page 7 for setting up quiscent current, these cannot be set.
Bit of history, the amplifier was lying unused for long time. Nothing in it has burnt. It was never opened earlier than this time, couple of days back.

While I was probing for voltages with DMM, with probe on collector of TR413 one of the fuses blew up. Later same thing happened on the other channel as well.
With the above as background can a Good Samaritan figure out feasibility of repair.
i am unable to upload service manual as file size is 7.3 mb
