There’s a ton of old rumors and “fixes” but it was recently confirmed by Microsoft that the main issue was failure of the flip chip interposer connections caused by incorrectly engineered underfill epoxy on early batches of GPUs. This is the same issue behind Nvidia’s Bumpgate and likely the PS3 YLODs.
BGA solder balls, x-clamps, thermal paste, overheating, etc were never actually a real issue. Heat gunning/towel tricking the console just warped chips enough that they temporarily made contact and would work for a little while. Only permanent fix is to replace the GPU with one made after they changed underfill epoxies.
Now that these consoles are 20+ years old there’s also aging caps and whatnot to worry about too.







I’ve gone to an Ace hardware near me half a dozen times for bolts, etc and I have yet to buy anything. If they have it in stock it’s sold individually and ridiculous prices. I just plan my projects ahead and get everything on McMaster now. Rural King and Tractor Supply have pretty reasonable selections for basic hex bolts, etc. if you need it that day.
