Power on I have had this receiver and only had to change a fuse. About 6 months ago I turned it on and it got stuck turning on and off repeatedly and the only way to stop it is to unplug it from the wall.

If the power button is not sticking, there is a short in the amp circuit of this receiver. It will need to be serviced.

Sounds like a bad thermal fuse or thermostat, check all of them with a multi meter for continuity. as for the heater going out I would check ur venting inside and out the machine. the fuses and heater blow out for a reason? Usually due to overheating issues? I suspect ur lint build up is the problem?

The most likely problem is shorted output transistors. This is a straightfoward repair for any shop that works on audio gear. Expect a parts cost in the $40-$50 range.

Google the system for the user manual. It may help with troubleshooting. Some better receivers have a fuse protection system and there is a red button on the back to push to reset. Be sure you don't have 2nd audio or monitor selected which can turn off main speakers. Try a set of headphones if you can to see if you get audio. Good luck.

I have the RX - V3000 Model. It turns on for a second and immediately turns off.

I had the same issue and tried changing inputs and etc. within a second of time. Nothing I did worked until, I opened the lower front access door and twisted the effects knob around quickly. This stopped it from turning off and it has been functioning normally since. Even turning it off and on again is without the issue coming back. I did try most all the buttons previous to doing the effects knob, in case that makes a difference in the long-run.

Before the issue you are having started on the unit I was working on, the owner of this unit did say he was having an issue earlier with the monitor SVideo jack in back, having a role in it powering off like this, about 6 months ago. To make it work then, he would remove the SVideo cable from the monitor jack, turn on the unit and then put back the SVideo cable once the unit was on and working. This allowed it to work for several weeks to a month before turning itself off again. He would repeat this procedure and it would work fine again for awhile.
Could be an electrical or grounding issue via SVideo that messed things up more and more?

Hope this works for you too!!
