At first I started getting color distortion, and eventually no video output. Would give me all green, and I got a video signal after I closed up the ventilation to over heat it, but that only worked a couple days before the discoloration and no video came back. Power button was all green though.
Took it apart and put new thermal AS5 compound on th GPU and bent the X-clamp for added pressure. That worked for around an hour while still dissembled. After that it went to 3ROD error 0102.
After that I took both heatsinks off and used Lawdawg0931's method with some minor differences.
Fixed the 3RLOD. No issues at all now, no freezing, works fine.
Ran the start screen from Crackdown for an hour. Played for another hour. Reassembled the console, put the hard drive back on and played the first level of Halo3. After that I played through the first level from RV2. Not a single issue.
Going to pick up GTAIV today and put it to the test with a long gaming session.
