Sziasztok!
Harman avr 255 protect hibával kikapcsol, hamar kiderült hogy az egyik végfok tranzisztor a ludas.Cseréltem is a párost (2sb1560 és 2sd2390) de továbbra is protect hibát ír és leáll.Ami furcsa, a hangszóró kimeneteket mérve a cserélt páros bekapcsoláskor -27 volt körülre lemegy, a többi aránylag nem sokat ingadozik, -2 és +3 volt között maradnak.Kérdésem hogy ott még lehet valami zárlatos? Ha kiforrasztom a cserélt tranyó lábakat és úgy indítok akkor elindul az erősítő.
Sziasztok,
Szükségem lenne néhány pioneer alkatrész beszerzési lehetőségeire és árára. A gép cdj350, és az alkatrészek cikkszáma:DNK5549(control panel),DAH2789(display panel),DAC2580(play button),DNK5657(usb cover),DSG1079(tact switch),dsg1117(tact switch).
Írhattok ide is és a mailcímemre is. Előre is köszönöm.
üdv
András
Köszönöm a segítségeket és az ötleteket, megkaptam a magyar importörtől a teljesen elfogadható forintosított árakat, így tőlük beszerzem a dolgokat.
Samsung midi hifi system scm-7450 - vel van egy kis gondom kapcsolási rajzot keresnék hozzá,de nem találtam sehol.
Tudna ebben valaki segíteni?
Köszönettel,Sándor.

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.
