Question about RCA Optimus/Stav-3880 Rcvr Parts - Board - Video
When I turn the RCA stav-3880 on it immediately goes to full volumn. Something with the remote control sensor I think?
Take the batteries out of the remote control, then apply a piece of black tape over the IR sensor, Unplug the power, wait a few minutes, now power the unit back up, does the unit still have the same volume high symptom? If so, remove the tape and see if the unit responds to any other commands(other than volume) from the front panel. If it responds to the panel controls, the processor is most likely good. very seldom is the IR transistor bad, if it is no input command will work.

That message appears when the amplifier draws too much power from the source. Since water went inside then most likely one (or even both) of the power amplifier IC's has been shorted - the big circuits attached to the radiator. You must open the receiver and replace the failed one .
