Question about Onkyo TX-SR500 Receiver
My receiver has a similar problem. So far I have found a pair of output transistors fried shorted E to B to C (Q6051 and Q6061) and the associated ceramic current limiting resistor array (R6101) failed open. These bad components will definitely be sensed by the protection circuitry as an overload condition. I ordered some replacement transistors from Mouser (2STC4467 and 2STA1694) and the resistor (RSS2WK-0.22 ) from Encompass.
I will let you know if this corrects the problem once the parts are installed. I also got a service manual from www.user-manuals.com which helps a lot.

Check your speaker cables are not touching at the back of your amp or speakers.
