PlayStation 3 Yellow Light of Death (YLOD) Fix Kit
UPDATE: The fix worked for about 3 months for me. Enough to finish GTA5 at least. I re-did the heat gun and thermal paste again and it worked for less than a week after the 2nd fix. RIP PS3. Still a great kit and it was worth it for me.
I just completed this fix on my A01 launch console, and to my surprise it seems to have actually worked. I'll update when I know how long it lasts. I was a bit skeptical, but for the price, and considering I am obviously 5 or 6 years past the warranty, it was worth a shot and I got my stuck disc back and hopefully I'll be able to get through GTA 5. Thanks iFixIt!
