Sziasztok! Információt szeretnék kérni Tőletek, a fenti készülék gondol egyet és magától bekapcsol. Kollégámé a készülék, kB. 14 éves a masina, ennyit tudok róla, esetleg valami automata be vagy kikapcsolási opció lehet? Előre is köszönöm a válaszokat!
Tisztelt Kollégák!
Rendelt valaki mostanában TDA8920BJ végfokot?
A hq-videó-tól vettem.
Az bal csatorna torzan, jobb rendesen szólt, kb 5 percig, majd végleg elköltözött az örök vadászmezőkre.
Előtte másik szervizben volt, ahonnan javítatlanul visszaadták. Állítólag. Persze az ícé cserélve volt arra a típusra amit én is kaptam. Gyanítom széria hibás lehet. A +- 28V megvan.
Köszönöm,Üdv, kovácsa
Üdv!
Szíjakat cseréltem eme szerkezet magnójában. Azóta ha bekapcsolom csak rápróbál a magnó motorra és CD-n marad. Nem tudok TUNER-ra és TAPE-ra váltani. Nem nyitja kazetta ajtókat se, se a CD tálcát..
Akkor is ez van, ha lekötöm a CD-t róla.
Mi lehet?
Kösz

Hello everyone, I'm having issues fixing this vintage stereo system, its amplifier boards seems to not be amplifying. The audio comes out at super low volume with the max. volume setting (the pot. works correctly). At first I had 20V and a constant hum coming out at the speakers output (saturated amp. I supossed). I changed the electrolytic caps., the 5218P component (TL082 replacement) and the NPN/PNP C1815 and A1015 transistors (this last thing helped with the amp. saturation and I do not have any DC at speakers now), but now the audio comes out super low. I measured the D1265 transistors off-board and they seem to be ok. Can anyone shed some light? Thanks in advance
