Sziasztok. Hibasan vettem egy Onkyo Tx8410r tipusu radios erositot. A hangsugarzovedo relei voltak hibasak. A bajom most az, hogy a  2 savos hangszinszabalyzoja igencsak sovany tartomanyban fejti ki hatasat, jo esetben talan +- 2 dB-t erosit/vag. Ezt szeretnem elfogadhato mertekre tornazni fel, es ebben kerem a segitsegeteket merthogy en ehhez mar nem ertek. SM van fenn a Tanyan. Udv.

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

Sziasztok. A cimbeli erositovel szenvedek. Hibasan vettem, csak az egyik bemenetrol mukodott. Mikor levettem a tetejet, lattam, hogy a bementvalaszto ic at van kotve. Rendeltem egy masikat, de ez sem akar mukodni. Mintha teljesen halott lenne, nem megy at a jel rajta - nincs egy bemenet sem kivalasztva. +- tapfeszek megvannak, a kapcsolat a kontrollerrel pin to pin leellenorizve. Nincs tobb otletem, szerintem 2 lehetoseg maradt: vagy a bementvalaszto ic halott, vagy a kontroller, bar a kivalasztott bemenetnek megfelelo ledek kigyulnak. Volt valakinek hasonlo esete?
