Adjust bass control to half position then feed loud signal,if it shut off adjust the bass contol to zero position,if it shut off again the defect is in the over load protection circuit it is already sensetive to loud signal.you may call the nearest audio amplifier technician on you.
Hope it may help you,

If you've had it "fixed" 3 times and the problem comes back either you have the wrong impedance (ohms) speakers connected or the power supply in the unit is the actual problem.
Happy new years,

I have found the battery location. It is roughly on the opposite side of the pc board where the display is. It basically faces the heat sinks. It's one of those small watch sized batteries and is soldered but sticking off the pc board with 2 leads. I could see that there was some leakage and corrosion. I still have to figure out what needs to be dis-assembled to get access to it so I can unsolder the bad battery and replace it. This stupid little battery seems to need replacing every 6-8 years! When it dies, it seems to disable the preamp section from passing any signal giving the symptoms that the amps are dead. However, if you try to use the pre-outs to an external amp, nothing. So, my guess is it has something to do with the preamp section. Anyway, that will be my weekend project to try to get at the battery and replace it with "longer leads" so it will be easier to replace in 6 years when it dies again. Great design Onkyo! You dumb-*** weasels!!!! I hate when companies engineer things to break so you are likely to pay them to fix it. Not this time, "No soup for you!"

Try some troubleshooting to check whether its the turntable or the the receiver.
What happens if you exchange the output cables of the turntable from left to right. Does the problem shift?
Does the sound changes from left to right speaker?
Similarly try on the inputs of the Receiver.. does the problem shift...?
This way you will be able to isolate the problem, whether with the receiver or the turntable....
Let me know, we can trouble shoot it further....
