Alright, so heres whats up. I just bought a XBOX 360 PRO on EBAY for $70 used. The system was described as working perfectly with occasional freezes, and thats not how it actually functions (yea thats an issue with the *** seller).
When used, the system will work fine for about 5-10 minutes (enough time for picking a team and playing 1-2 innings of MLB 2k11), and then everything goes to hell. The screen starts to flicker a bit (begins at the bottom, then spreads to the middle and top), then white and black lines will take over the screen. Sometimes it wont be too noticeable - just blurry, but then other times it gets bad - a lot of static, almost like a tv not connected to cable with the game showing in the background. Sometimes it will stay that way and freeze, and other times it will revert back to normal only to *** up 5 minutes later. There has been NO RED RING. I have not received any red rings and I have not gotten any E74 errors. The issues also extend beyond the individual game into the dashboard.
I have attempted to clean the 360 by spraying air into the console to remove dust, though this has not helped. As the 360 is beyond warranty, I attempted to open up the console, though the previous owner stripped the torx screws.
Am I screwed? Anyone had these problems and found fixes? I'm assuming I have to find a way to pull out the sripped screws and remount the heat sink, though if its not the fix I need to know.
