So it seems I need to either reflow or reball my PS3. The GPU seems to be acting up and the most likely culprit is cracking solder thanks to Sony’s use of lead-free solder.
Does anyone know what reball and reflow are in Chinese? I tried looking around the Interwebs, but couldn’t find it.
Depending on the cost to do the reflow, you could also replicate this for free with a blow dryer directly onto the GPU. There’s a few how-tos out there on this “ghetto style” method, but it has been successful for people.
