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 [email protected]@h to work with?? Help me with this.

Re: harmon kardon stereo reciever avr130
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

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.
I think I had the same problem. This is how I fixed it.
I have my vizio 42 hooked up to a Harmon Kardon surround sound, and the digital cable box. Essentially, I can adjust the volume 3 ways - through the tv, cable box or av receiver. The humming sound happens when you have the volume maxed out on the av receiver and not the cable box.
For example, the sound level on my Harmon Kardon goes from -10 (lowest) to 10 (loudest), with 0 being the middle ground. The buzzing was happening when the Harmon Kardon was set to 10, and I was using the cable box volume to adjust the sound. To fix it, I turned down the volume on my receiver to 0, which may be about 50% max volume of the receiver. Then, I switched devices and used the volume on my cable box. This got rid of the static I was getting. Hope that helps.
check the wattage of the speakers, they could be drawing too many watts from your amplifier, if you plug in a speaker that's more than the channel, it could harm your amp.
for example a 200 watt stereo, with 4 channels that equals 50 watts per speaker.
Try hooking up a yellow video wire from the back of the AVR 225 Monitor out. Should be at the end of the 7 or 8 yellow video ports on the back of the stereo. Next plug the other end into a yellow video in on a t.v. Get your remote, (Harmon/Kardon) and make sure the t.v. is on the correct video input and hit the OSD(on screen display) button on your harmon remote. There should be a setting in there that says VFD under ADVANCED menu option that allows for turning the front of your stereo lights on and off and dimming them half way also. OFF/HALF/FULL are the 3 options I believe.
If this doesnt solve it your display may have crapped out on you.
