Onkyo SR502 Shuts off by itself

My Receiver shuts off by itself. It will stay on for a couple of seconds and shut off. I was able to get it to stay on but it sounded awful and it got uncontrolanbly loud. I went to turn the volume knob and it shut off immediatly. What is wrong with my baby? How much will it cost to fix? A friend of mine thinks it's a blown fuse, is that true? Thank you in advance!

Hello! One of the channels in your unit has shorted output transistors and is sending about 60 volts towards your speakers. If your unit has an output chip ( I don't ever remember seeing an Onkyo with a chip though...all discrete transistors ) it is shorted. Your unit is well worth repair. Onkyo is an execellent unit. Please rate this solution! Thankyou!

Not worth repairing until the root cause of the failure is proven.
The reason being is that you can have it happen again if caused by any of the devices attached to it, such as inefficient speakers.

Can you use an Onkyo RC-771M remote control to operate Onkyo receiver TX-SR502 ?

Unfortunately, the RC-771M remote doesn't control the TX-SR502. It will only work with these Onkyo models: TX-NR1008 and TX-NR808. The RC-567M is the one for the TX-SR502; replacement remotes that are exact replacements are still available from various places including .

Since the TX-SR502 was released in ~2004, that replacement remote probably won't control other devices that were released in 2004 or later. Onkyo changed its IR code programming before the TX-NR1008 was released in ~2010 and the RC-771M can't communicate with the older receiver. The manuals for the receivers listed above are still available from Onkyo on the product page under the Downloads tab.

I wish that I had better news for you.

Onyko tx nr616 receiver keeps shutting off. Only stays on for approximately 3 seconds. Can you help?

The amp protection circuit has been activated. Remove the power cord from the wall outlet immediately. Disconnect all speaker cables and input sources, and leave the AV receiver with its power cord disconnected for 1 hour. After that, reconnect the power cord and reconnect an input and a pair of speaker wires onto the unit. If the receiver still does not turn on than you will have to bring it in for service. Turn up the volume and if the receiver doesn't shut down, power off the receiver and add another pair of speakers. Power up the unit again and turn up the volume. If it doesn't shut down, power off the unit again. Now connect all your input sources and turn on your receiver. If the unit shuts down again, your unit will need to be further serviced at an authorized Onkyo service center.

Hi have a Onkyo TX-SR601 after using it for a while it shuts down.

The problem could be bad solder connections on the main, or the audio outputs are breaking down when they get hot.

The receiver keeps turing it self off after a few min. in all modes

Check all speaker wires for shorts as this can shut down the receiver. The end may protrude too far into the chassis and touch the metal frame, this could cause a short. Try disconnecting one speaker at atime to eliminate a bad one.....

Plugged into outlet. Spark. When powered up,

First, try plugging a lamp into the socket and see if that works. Next, plug the receiver into a different outlet and see if you have the same problem. Usually, when a receiver shuts down after a few seconds, the problem is a shorted output transistor causing the system to go into auto-protect. A blown transistor may be caused by speaker wires touching at either end. Just a stray strand of wire can be enough to cause real problems.

My Onkyo tx-sr606 7.1 receiver turns off by itself

hi, when the unit shuts off by itself, it means that the protection circuity inside has been activated. it can be a problem with the receiver itself or it is just detecting something hooked up to it that can cause possible damage so it shuts off.

you would need to disconnect everything from the back and by itself, try to turn it on, see if it will stay on and then crank the volume way up to max. if it stays on, the receiver is ok and you then need to rehook your devices one by one starting with the speakers until you determine the one causing the receiver to shut off.

however, if the receiver shuts off and won't turn on even by itself, it means that the problem is internal and it either has to go back to your dealer for an exchange or it has to be sent to a repair center for servicing.

hope this helps a bit.. ^_^
