Yesterday, I noticed I had no signal on this receiver. I tried a red button reset, unplugging for 15 seconds, running a new HDMI cable, even switching HDMI inputs on the TV. Nothing worked, except for connecting the receiver via S-Video. When I went to unplug the receiver, I did notice the box was rather hot (not burn your hand hot) but close. I let it cool off for a while, thinking that may be part of the problem, tried again, but still got nothing through HDMI. Is there anything I'm missing here? This box has been fine for 3+ years. I doubt I have 2 bad HDMI cables all of the sudden. Could the HDMI output on the receiver go bad? What should my next step be? Thanks for any help.
