Onkyo TX-SV515proII védelem tilt
Üdv!Kaptam egy nagyon leharcolt erősítőt,nem tudom megéri-e vele foglalkozni mert a távirányítója sincs meg, de a végfoka az én stk-mhoz képest komolynak néz ki. Keresnék olyan vállalkozó kedvű szakembert aki esetleg elvállalná a javítást, én ugyanis autószerelő vagyok,szerintem nekem túl nagy falat lenne.
Onkyo TX-L20D service manual request
Can anyone help me with this service manual?
I have a unit with damaged Ethernet port.
Onkyo A-830 végfokhiba.
Sziasztok!
Abban kérném a segítségeteket, hogy egy Onkyo A830-as erősítőnek kellene a rajza. Pontosabban elég volna csak a végfokról. Föltettem az SM-keresőbe, de pont olyan nincs. A hasonlóak mind IC-s kivitelűek, ez pedig tranzisztoros, mégpedig jó sok tranz-al van felépítve Jó volna, ha valakinek volna a végforól rajza, mert a többi ákör, és a másik végfok működik.
Köszönettel:
Attila
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
