Power transistors probably degreased or the greas had hardened and doesnt conduct the heat anymore. Quite touchie work, would suggest it only if u have some knowledge about soldering electronics.

Disconnect amp power harness. fault will go away. time to troubleshoot a little. most likely a transistor. all that heat and no proper vent add a little dust. if trans. are good. dust removal and a fan did it for me

If you took all the speakers off the reciver then it still goes into protect, the reciver detects DC on the output lines. That means there is a short in the output stage of the amp. It could be an output device, or a diffencal Transistor. If you can trouble shoot solid state electronics then you should be able to find the faulty, but if not your experienced at electronic repair, am afraid it may cost more then the reciveris worth. Good Luck PS please dont forget to rate this thread

SOURCE: the protector light comes on
The receiver has a short in the audio output stage in at least one channel, the parts must be replaced to bring it back up to normal operation.
