Re: KENWOOD VR-507 RECIEVER
Thats because you are pushing the amplifier too hard. Its going into protect, or it cannot supply the power so it cuts off. 400 watts is too much for it to handle, you are really pushing the amp, and it can blow the amp. Get some speakers that match the impeadance, and match somewhere around the amp specs

The receiver's out put sections are grouped in pairs. Front left and right in one output, rear left and right in second output, and center channel and sub output on the third. Sounds like a semiconductor or semiconductors have gone bad in the center & sub output.
Very possibly a problem with overdriving the speakers and the breaker inside the receiver is "popping" in order to protect the outputs from being fried. check the ohm rating of the receiver to the speakers and lok for damage to any of your speaker wires. also make sure the wires are not crossed or touching in the back connections to the equiptment.
PROCESS OF ELIMINATION: connect each of the other speaker in the working to check to see if the wires and other speakers are working. If all speaker play when connected to the working channel check all other cables and connections....use the tuner as an working source to test. If that doesn't help then you may have an bad channel in your amp and may need to be repaired.
Hi changeman5 Have you tried to do a full reset on the unit. Disconnect from the wall for 24 hrs. Then try again. If the problem persists, it may have power supply issues, or a DC offset problem shutting it down. If you are game, I could talk you through some more diagnostics...
My Kenwood VR-507 had been working great. I hadn't changed anything. I hadn't even moved it. It just suddenly stopped producing sound. It didn't just stop while it was on. I had turned it off and when I turned it back on, nothing. I tried running the speaker setup to see if it would output pink noise, I could hear the test sound, but I couldn't hear any audio from the TV or DVD player..
If you have your reciever in an entertainment center that is enclosed or a tight fit for the reciever you need to remove it and put it on top of the center. I have a VR407 and it was doing the same thing. This keeps your unit much cooler and the overheat relay will not turn it off. also I found it much easier to add or wire components much easier.
