Bad News, it will need repair, I suspect output transistors.
Unless it's still under warranty, you may be wiser buying a new receiver rather than envesting $70 to$100 into this one.

Receiver turned off after power on


I can see two possible problems.1: your receiver wants to take too much current and it shuts down the relais to the speakers, or,2: The hold contact of that relais cannot keep it's voltage and shuts off the speakers after a short time.
Check your end transistors for shorts and/or see what the voltage does at this relais. A faulty capacitor perhaps?

I have a Kenwood VR-804 surround system receiver. Stand by light keeps blinking when turned on but no sound no nothing when turned on just powers up for a few seconds then shuts off with light blinking. I...


Blinking indicates that the power source has shut itself down because another component has died and it's shorting it. Unless you have experience in electronics it's time to take the receiver to a repair shop.

Look at inside at capacitor and fuse but they seem ok. again once i turn it on, it would automatically shuts off after a second.


When a system shuts down after a few seconds it is the self protect circuit shutting down power to the outputs to prevent (further) damage. It may be caused by frayed speaker wires, bad speaker voice coils, or blown output transistors. First, turn off power and remove all speaker wires from the receiver. Turn it back on and see if the problem remains. If it works OK, inspect each speaker wire at both ends for loose strands and correct these. Then, hook up your speakers one at a time until the problem reappears. That speaker or its' wiring is your problem. For safety's sake. turn the receiver off before connecting each speaker. An accidental short of the output terminals can be disastrous (and expensive).

Yamaha rx-v456 av receiver, shut down with optica cable


Does it work without PS3 attached?
When receiver turns off, it is usually due to badly connected/configured speakers. Try powering on the receiver without speakers.

Won't turn on.standby light on,fuse under cover is good.what next? onkyo tx-sr605


The only thing to test would be to disconnect all speaker wires at the receiver then turn it back on. If it still won't turn on, it's an internal power supply issue and will need service. If it turns on, post a comment and I can walk you thru further troubleshooting. Hope this helps

Enters standby after being on for only a few seconds.


Sounds like either the volume is turned up too loud, or you have a short. Have you tried disconnecting all the speaker leads from the rear, and then powering it on? Usually if it turns on for a short time and then shuts off, it is throwing itself into protection mode.

I turn on my Pioneer VSX-D509S 5.1 surround amp comes on for a few seconds and then it says "powering off"... and shuts off


Disconnect all your speaker wires from the back of the receiver and turn it back on. If it shuts off, you need to have it serviced. If not post a comment and I can walk you thru troubleshooting. Hope this helps
