I would like to know what the hell on earth does these service station guys do that get the Onkyo 6.1 TX-SR 502 receiver out of the protection mode. I am curious as my service station folks have given me a laundary list of electronics components like a power amp, an op-amp, heat-sinks, endless numbers of resistors, capacitors and diodes.............. Pl looking for genuine advice ........folks Can something be done at our end to unlock this box????..
From LANCE P: I fixed it. Be sure that all your speaker connections are perfect. No element frays that can arc, no +/- problems, no single barely connected wire. My problem was volume sensitve and I evidently had one + wire that was loose in the back. I corrected it and ran it all day with surround and good volume with no problems. So diligently check ALL YOUR SPEAKER CONNECTIONS, both in the back of the unit and at your speakers
