Question about Harman Kardon AVR 635 Receiver
Every time I turn on my receiver it works for about 30 seconds and then it cuts out and goes into standby mode. This problem just recently started and happens everytime I turn the power on. I tried a system reset but this did not fix the problem. I'm guess it is some kind of fuse problem but I am not sure.
I had a similar issue as yours on my HK AVR635 and I had the speaker board replaced (internal part where the speaker wires plug into...part/labor under$150CDN). Not sure the exact name of it but when that was replaced all was well.

No. If your using all the speakers that came with the unit, and unit was working correctly before then, your problem is an indication of a more serious problem about to occur. Your unit is detecting an over current situation. It could be something like a idle bias problem, or alighnment, or theres a part thats going bad and not up to specs. Oh Yes and one of your speakers could have a problem and just hasent went bad all the way yet. If it was my reciver , I would have it bench checked with some resistive loads and see on the scope, where the units clipping, if it is. If not the tech will know if its a zero crossover, idle bias or an offset thats bad. Without the proper equipment this is not a repair for you to attempt , unless of course you happen to be an electronic tech? Good Luck
