Aiwa receiver AV-DV75 powers up then down instantly

You'd be MUCH better off to simply eat the loss and buy a new receiver, seriously. Sorry. It's fried!

We can't make assumptions that all is connected and selected properly.

This most likely means you might have some speaker wires crossed in the inputs somewhere. It shuts down to make sure it protects itself from burning up.

Disconnect all speakers at the receiver and power it back on. If it stays on, check your wiring and speakers for shorts, if it cuts out, it needs to be serviced. If you need further in depth troubleshooting, post a comment and I can walk you thru it. Hope this helps

There may be a short circuit in the speaker terminals.

Disconnect all speakers and try it. If it works troubleshoot each speaker one at a time. Shorted wires are indicated.

Same problem here...I determined that if you unplug the receiver for a few hours, it will work again for a week or so.  Someone else on this website said that it had something to do with the power relay switch:

Its the power relay switch which is no longer made.

I have been looking to see if there is a class action suit on this receiver

I bought my AV-DV75 from Best Buy about 10 years ago and it still works. However it did stop working a while back. I don't know why. I alsmost threw it away. But I unplugged it for a couple of days, then plugged it back up and it came back on. It is still working. Maybe that will work for you.

PS
my center speaker quit working recently. If you decide to sell your AIWA speakers will you please email me?
