If the unit will still not work consider having a tech look at it.

SOURCE: My Sony STR-DG500 wont turn on just clicks once and nothing.

Sounds like faulty psu (pwer suply unit) Amp is going into protection mode. Disconnected all speaker and av wires (only power) turn up volume and see if it stays on. If not psu, sounboard or volume function faulty. If on, connect one speaker L or R. Go to tuner mode to tuned radio station an listen for sounds. If on, connect speakers and av cables one by one and test each one on its own until amp switches off, Investigate from there were problem is. Make sure speakerwires is not shorting out.

SOURCE: STR-DH700 won't power up unless I unplug-plug it.

This is a logic problem with the internal microprocessor. A quick experiment: Turn the unit on for about 2 minutes and shut it down. Doe sit power uip in this case? If so, I'd suspect that the heat generated during normal operation is creating an internal problem thaty is preventing the micro from recognizing the "off" condition. The power data line is hung and is not being recognizwed by the micro so any attempt to turn the unit on will fail. The unplug/re-plug essentially clears or resets the unit.

If the unit is new, return it for warranty repair. It will be important to describe when the unit fails however. Try to see how long it must remain on for the problem to occur.

Update this with your results if the unit is not under warranty and we'll try to narrow it down.

Thanks,
Dan

SOURCE: i have a sony str de445 and it overheated one nite

you might have burned up some internal parts, it is very important that you keep your unit well ventalated so that it has less of a chance at overheating, check for any internal fuses that might have blown.

I've got a Sony STR-K880 Cinema surround system and the remote control won't work it anymore! The only thing it will do is turn the system off when I push the'AV I-O' button and the &#


I had the same problem. Found the fix in this document
STR-K880 service manual
On the amp, while powered off:
"While depressing the INPUT MODE button, press the POWER button to turn on the main power."
You may need to do this more than once.
This switches command mode between AV1 and AV2.

Str-de685 WHEN I POWERED I HEARD A CLICK BUT EVERYTHING OFF NO LIGHT.I CHECK BOTH FUSES AND ARE OK.


There is a relay on the power supply circuit board that might be faulty or has bad solder connections. If this relay does not work, power is not applied and everything is "dead". I had to re-solder the speaker relays on my STR-DE675 because they had cracked solder joints which made them work intermittently. It's possible that the power relay is what is causing your problems. If it has bad solder joints it might click, but power might not be able to pass trough the joints.

Does it still click when you turn it on or did it only do this once?
