Over the last few days my Yahama RX-V 800 dd/dts receiver has been shuttng off as if there was a short or an overload such as when two speaker wires touch. I have gone through every external device to see if there was something not right with any of my connections. As of this morning the receiver won't turn on at all. I have disconnected every component and have the receiver sitting on my table right now and plugged into a completely different outlet away from my system and it still won't turn on. When I press the power button it click as if to charge the capacitors, but immediately clicks again to shut off (all in les than .5 of a sec). So it seems to me that it has something to do with that. Can anyone electronic gurus give me a hand in what this might be. The receiver is well out of warranty I believe and I really don't want to drop and cash on a new one. Please help!
