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:
Kaptam egy Philips SBC HC8635 tip vezetéknélküli fejhallgatót a dokkoló/csatlakoztató egység nélkül, ami hazaköltözésük során eltűnt.
Van rajta egy ki-be, Tuning, Volume gomb.
Tettem bele elemet,és a hangológomb kis elmozdításakor megszólal benne valamelyik tévéműsor, de nem a tévén éppen futó műsor, kikapcsolt tévé estén is működik, nem mindíg ugyanaz jön.
ISMÉTLEM, a dokkoló egység nélkül!
Rejtély!
Nem találok róla sem rajzot, sem kezelési utasítást.

I am looking for a Service and/or User Manual for the Cassette Player DENON DRM-800. English or German please
Thanks in advance
