My M 504 power amp is having intermittent trouble the protection relay

Post  crockett645 on Sun Oct 07, 2012 12:58 am

My Onkyo M 504 power amp has started to give me problems..
I have been having intermittent trouble with it. When I turn it on sometimes the protection relays do not turn on. I can turn it on and off several times and then it will be fine. Then some times it will only stay on for a short time then the protection circuit will shut down. I tried changing the input source to see if that might be the problem it will still do it on occasion. I tried changing speakers and still the same results. Can someone help?
Thank you,
