250GB Slim no HDMI signal

Hi guys, im here vent my frustrations really as I have tried everything (and I mean everything!) to no avail.. Even throwing it but that didn't fix it weirdly, made me feel a lot better though lol

Basically the 360 is normally connected to a denon avr1910 av receiver which is then connected to an optoma hd33 projector via hdmi1080p. Sometimes take the 360 to into my dining room and hook it up to my asus 1080P monitor via hdmi and ive done this loads
of times and never a problem.

Did this one day and all of a sudden no signal through to denon.. 3 x full hd displays and 1 1080i but still hdmi so plenty to try. From here ill just list the different scenarios and the results:

Asus 1080p monitor - Fully working with no issues what so ever :S

Optoma HD33 via AV receiver - no signal at all

Direct to Optoma - Fuzzy green screen

LG full hd LCD TV - No signal at all

Samsung plasma 1080i via hdmi - no signal at all

For all the above non working displays I have tried:

Different hdmi ports

Different hdmi cables

Resetting display settings (holding Y and RT)

Blind setting resolution

Changing resolution on working monitor to lower ones then connecting back to the non working displays

connecting via composite av cable (which works on all displays btw) and selecting different sources going back hdmi etc etc

I have also tried different sources in different ports with same cables as 360 and all work perfectly.

I had 2 PS3's over the years since its launch and apart from the odd freeze up now and then (can count on one hand in fact the amount of times in fact) no problems at all, absolutely fuming that I got rid to try out a 360 only 2 months ago and its already
knackered...

Thanks for listening.

HDMI Video Blacking out

All of a sudden my console started to black out at random times. It's only with the HDMI though. I've tried using a different HDMI cable, no luck; same problem. I tried using a different TV, same problem. The video (and audio) cuts out from anywhere between
3 seconds to minutes. My TV also states, during this blackout, "No Video Signal" and "Unsupported Video Signal".

Is it possible for the HDMI to just crap out like this? Should I just send it in for repairs?
