ONKYO TX-SR606 kimenetein se kép, se hang. (megoldva)
Sziasztok! Nevezett készülék rádióról és analóg bemenetekről rendesen üzemel, de digitális bemenetekről nem. Kimeneteken szintén nem jelenik meg semmi. HDMI csatlakoztatását felismeri. Valaki találkozott már ezzel a jelenséggel? (Gyaníthatóan ez valami típushiba lehet, ezért vetettem fel a témát, mielőtt jobban belemélyedtem volna) Üdv,Z.
ONKYO TX-DS494 low volume problem solving experience
Hello. here is a message to share my experience in solving a problem that appeared on the home-cinema amplifier ONKYO tx-DS494. In order to sell this amplifier I had to check if all the outputs and all the functions works properly. On the back of this amplifier you have to frontal output : A and B. I connect a pair of speaker on A output : no problem. I can adjust volume. when i connect the pair to the b output and turn the volume knob no sound came out of the speakers until I reach a level defined by I don't know what. :hmmm: My volume level goes from 0 to 80db ( if I remember well ). from 0 to 23 db no sound and when I reach 24 dn sound increase and stabilize. With hearphone connected, i don' have this problem so I conculde that amplifing transistor could not be incriminated. I checked on the service manual and saw that there are two or three component that could be the source of the problem : the main processor, some capacitors on the output PCB and relays. I began testing capacitors: no pb. then I thought that if cannot be the main proc because it ( I think ) works in a binary mode: it works or it doesn't. so I decided to switch between themselves the two relay and :super: : it works. The relays was in fault and did not switches properly. here is my experience in repairing an amplifier
Onkyo TX-SR501E erősítőt nem lehet bekapcsolni.
Üdv' Mindenkinek. Kezelőn stby 5V megvan, stby gombon is. A relét, mi bekapcsolja a cuccot egy tranzisztor kapcsolná, aminek a bázisa valahonnan arról a digitális förmedvény panelról jön, ami a mindenféle av és egyéb dolgokat is kapcsolgatja. Ha a relé meghúz, villanyok megjönnek, de továbbra is agyhalott. Itt feladtam. A cucc pesti. Ha akad, ki elmolyolna vele, küldjön privátban egy telefonszámot és összehozom a gazdival.
