I hate to bump an old post but Light-It-Up may just be right on the money (litterly for me) with this issuse of sound but no video. I fix xbox 360s and basicly this is the same problem with the RROD ( red ring of death). they put some cheap ass thermal heat compounds on these systems and expect it the cool processors of this kind of power. I say if its possible like the 360s are take it apart remove the fan cooling the system and just turn it on. if that doesn't heat the system get a heat gun but be very careful. once its heated enough remove the old thermal compound with WD-40 or alcohol and a Q-tip and a cotton clothe then re=apply some good thermal compound like arctic silver.
P.S. I've never used WD-40 to clean a cpu or gpu of bad thermal compound but people say it works better then alcohol.
P.S.S. there is a youtube video of a guy with a overheated CPU and he uses a heatgun to fix his YLOD problem. Search for PS3 YLOD Fix Part 1 of 2.
Sony uses a much better looking compound than Microsoft, but it can still get dried out/cooked.
