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.
