Receiver shuts down as soon as I turn it on

[spidey07]

I "inherited" a damn nice receiver, top of the line yamaha from 2001 I would think. Has dolby digital and DTS. But here's the problem, it shuts down and powers off some 2-3 seconds after turning it on.

Normally I would point to protection setting it off, but it does this when absolutely nothing is connected. No speakers, no nothing, just a power cord.

Any thoughts? Internal fuse?

It has physical bridges between pre-out and amp-in. I'll get model number.

Open it up? As a wild guess I would think it's a bad power supply or blown caps.

Thats my next step. See what's burned.

Are you sure your speaker wires are not shorting out on the chassis?

Yes, that would be the first place to look. But the receiver has nothing connected to it other than a power cord.

oh wow

Yeah, I'm going to open it up and sniff around for burny bits. Just wanted to know if there was something simple I could look for (internal fuse).

More I think about it, RKS is probably on the right track.

I had an onkyo that did that... It was under warranty so I disconnected everything took it to a service center, said it was fixed... plugged it all back in set it all up and it started doing the same thing in less than a week.

They claimed it was bad solder joint. I never got around to fixing it since hooking everything back up and setting it all back up again takes a while ... I eventually threw it out with the trash and bought another amp.

My first receiver would do that after warming up. I sent it out for a costly repair and it was fine for a bit then did that too. I like Onkyo's but man I hated that thing. My new receiver is a Denon.

I've had plenty of amps repaired. They are never fully back to functional IMHO.
