I had the same problem with my TX-SR601 receiver. Solution: I changed the capacitor C766 (100uF/6,3V) on the "DSP and main microprocessor" or "U1" board. This capacitor is responsible to keep the settings in the memory. It is directly next to the SRAM ICs (Q705-706) (type: CY7C1019BV/CV33-15VCT). Now the receiver works properly again.

I added the subwoofer wires to the right and left front speakers.

have you tried to reset it to factory defaults yet? If it has a vcr button on the front, then hold the vcr button and press power...it should say reset on the front. Might not help, but worth a try.

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

Hello there, if you have switched speaker wires and yet they still dont work then the problem most definitely needs a repair to be carried out. Although as long as the entire unit functions and its just the right speakers that dont work in zone 2 then the problem is minor and would not need a total replacement.Although the problem would need to be looked at to be able to determine the exact source of the failure but usually is a fairly meager anomaly in the system and can be easily fixed.
Hope this support has been helpful?

Your Onkyo has no suitable input for turntable. I suggest you to use this or this preapmlifie, connect the turntable at the preamplifier input andthe preamplifier output at any available input at the Onkyo (cd, tapein or video in, at the red and white connectors). Of course you can buy any phono preamplifier from any shop and connect it with the same procedure. The models before is just a sugestion.

In case of a problem or clarification or further details needed, don't hesitate to post me a reply before rejecting my answer.
If you are satisfied, rate my solution with the "thumbs" or (even better) add a testimonial.

Thanks and regards

Push both connectors on with a twisting motion. Tradionally white is Left and red is Right.

Do you have the manual?

Randomly lost the the ability to produce sound is what you mean. It already does produce sound randomly.

You don't mention any conditions common to the onset or say if it cicks prior to going silent, which would indicate an activation of the self-protection circuit.

Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.

Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.

You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.

If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

Check for loose speaker connections at the speaker as another possible root cause for intermittent shutdown.
