Re: Onkyo TX-SR507 stuck in standby mode/protection mode, relay clicks one time
Have you tried replacing C922 or at least bridge it with another 1000µf to see if it will stay up.
Its kind of hard to tell if the relay is droping out because the 12 volts can't keep it latched or the POWERD line is telling it to turn off due to a fault.
Are the + and - 52v both ok
There are also two lines IPROTECT and VPROTECT, check what there voltages are, they may be telling the amp to shut down.
