I bought this receiver a while back to replace a pioneer that had failed, mainly because it would turn off after being on for a second or two. The kenwood has really been amazing for me, and today, I was listening to some music from my computer, and the thing turned off. I turned it back on, and then a few minutes later it went off again. It won't stay on for more than half a sec before it turns off and blinks standby. I unplugged everything from the back and the same thing happens. I did pick up some Jamo surrounds and center a week ago, but I don't think they could be the cause.
