Greetings everyone!

Accidentally I got a free AV Multichannel Receiver (Pioneer VSX-826), it looks fine, and shows perfect signs of life, but outputs no sound. Even to headphones (though the different circuit should be used for this than for speakers?). Tried master reset several times - no success.

So the question here if it does make any sense to try to find a place to diagnose and fix it (does anybody know it?) or it will cost so much money, than it's easier to rubbish it and buy another for that amount of money.

Any suggestions?

It's a 10+ year old receiver, I dunno what the current prices on TM are but probably just the cost of getting it looked at will be about the same as the price for an equivalent-aged one on TM.

It could be a simple fix like a recap (replacing aged electrolytics), but if all audio output is gone and it needs some custom IC replaced...

Just out of curiosity I had a quick look for a service manual in case it was something as simple as tracing a signal through it with a scope... their "service manual" is a list of which PCB modules to replace if there's a problem. It's probably a case of "sell it on TM for parts" unfortunately.

You could try a Repair Cafe. They do good work and might hopefully be at least able to give you an idea of repairable or paperweight. I might be heading there with a vacuum cleaner shortly.

Thank you very much for your answer! That's what I thought... Still - I might try the ideas below before selling for nothing.

Did you get this fixed or was it uneconomical?
