Question about Harman Kardon AVR 130 Receiver
When I turn the volume up to about maybe 50, it shuts off and says protect. It does this when I watch dvds or play my Xbox 360. What the hell is that? And why is the remote such a bi@@h to work with?? Help me with this.
Say PLEASE!!!! LOL just pullin your leg. I have found most reciver remotes are a B&*&h to work with as well as program for other componets. Now for yor problem at hand. It could be a speaker partially shorted and on a high current such as a loud input to the speaker its loading down the reciver. Also could be a fault with the idle current or zero offset voltage, or an Idle bias alighnment, or fault in the recivers amp section. The only way to test this amp would be have a service tech hook up the amp. to some load resistors, hook it up to a scope, and insert an 400 cycle to 1000 cycle tone at .775 Millivolt and see when the outputs clip if at all, and this will tell an experienced tech where to look for the problem you describe. You see my freind there are no user serviceable parts inside this reciver for you to trouble shoot unless you know how to use specialized equipment and troubleshoot solid state electronics. Good Luck

Tips for a great answer:
Disconnect speakers and wires. Bad wiring or defective speakers may be loading the amp down and causing the protection circuits inside to disconnect (no sound). If the HK is heating up (beyond what you perceive as normal) with no wires or speakers connected then you have a problem requiring expert repair.
