What can be done to repair this problem?
Answer – Nothing currently. There have been many reports of people “buying time” by “reflowing” the GPU. First, chances are you’re reflowing the wrong chip.
You may ask.. “If we’re reflowing the wrong chip then why are we seeing positive results” You’re seeing positive results because you’re action of applying heat to the PCB is warping the board. It’s changing the clearance under the problem area of the CPU allowing the solder sphere to temporarily make contact. If you attempt to “reflow” the CPU you’ll find that you can’t get the CPU solder to reach “liquidus” or “melt” because of the pervious extremely high temperatures that it’s been subjected to up until the problem surfaced.
