Hi there,
I bought my console on release date and have had absolutely no problems whatsoever until now. I've been using it with HD connectors to a perfectly functional HDTV for the entire time I've owned it. Today I was playing Oblivion for about an hour or so when suddenly everything on the screen whent grainy as if somone had turned the colors down to 16-bit, everything was a bit discolored as well. I shut down the console immediately via the controller's Xbox button, the gray pull out menu was also discolored and grainy, and felt the console to see if it was overheating. Finding that it and the power supply were only midly hot I attempted to power up the system again, I heard the startup woosh through my speakers of the console starting up but my display stayed blank... not even a flicker, nor were there any red lights on the console to be seen, just the regular start pattern of green.
I waited about 15 minutes for the console to cool down and tried again with the same result: normal startup pattern of green lights on the console, can hear audio, no video whatsoever. I then proceeded to powercycle the console, no good, then I tried changing the port it was plugged into on my TV... still nothing, then I tried changing it back to regular AV cables... still no good. I called support, they suggested that the cable might be defective since there was no orange lights or red lights or anything else that might indicate a hardware failure and offered to ship one out to me, I declined instead going to my local electronics retailer for a replacement which cost me 50 dollars. Tring this out and getting the same result I tested the TV itself with several other AV devices in the ports I was trying the 360 with, they all worked.
At this point I'm probably going to have to trade the system in at my retailer with the extended warenty that I purchaced but I thought I'd make this post to see if there was some obvious thing I didn't try or a special button code to magically make things work again that I could try..... anybody? Please?
