My brother-in-law recently gave me his broken Xbox 360. Unlike most other broken 360's out there, there were no 3 red-rings-of-death (RROD) indicating some major problem. Instead, when you turn it on, it seemed to start up just fine. Well, you could hear the audio of the startup, but there was no picture.
Get the XBox 360 Red Light fix – Guaranteed to work in less than 2 hours.
So I took the thing apart, to see if I could find any obvious loose connections or solders. Nothing. So, I did some digging online. I found out that you can fix it much the same way as you would the common RROD issue, by removing the x-clamp from the GPU, and using screws to reseat the heat sync.
I pieced together the fix from around the web, and took the following steps to fix my video-less 360:
- Downloaded this guide. (highly recommended)
- Used the tips from this guy with the same problem
- Then, used this step-by-step tutorial on removing the x-clamp
- And just to make sure I got it right, watched a number of videos on Youtube showing how to disassemble the Xbox.
I did however make a mess of some of the plastic casing of the system, but who cares, it's working! I also managed to actually get the RROD when I put all the casing back on, so now I just leave the top off. Go figure.
