Answer to: MBP A1226 Logic Board last resort fix for nVidia video chipJust a quick update, while (1) taking the machine apart and using the blow-dryer on NVidia chip brought the machine to life initially, it didn't last. In about 2 months time, the blank screen play started again. Repeated (1), and the problem went away the second time. Though this time I figured I should try to change the logic board and around $300 price from acendtech seemed more reasonable that the $799. Replacement went well and everything appeared to be in order. In about 2 weeks time, the funny flashing RGB pixels started to appear randomly on the screen, and the problem got worse to the point where the screen freeze becomes a fairly regular occurrence. The only recourse at this point is to perform the hard reboot. Finally, I called it quits on all the tweaking or twiddling. Paid 10% or so return penalty to acendtech and bought myself a mid-2010 Mac for under a gran. It has been 6 months now and I can finally focus on using the Mac then worrying about the fixes.
Answer to: MBP A1226 Logic Board last resort fix for nVidia video chipI have a late 2008 model of MBP and it went dark a few days ago. I can confirm the heat effect works. Took the logic board out, cleaned the thermal paste from the nvidia chip, heated it with hairdryer at close range for 3 minutes twice, re-applied new layer of thermal paste, and assembled the laptop back together. And it now works. Two days and going and all is well so far.
