I have recently got a powerbook 1.25GHZ off ebay that had a display problem. I was wishing it was the actual display and not a problem with the logic board. Turns out it is the logic board as when i connect an external display i get the same result. Anyone seen something similar? I guess it is just the vga because the laptop seems to work fine. Is there a way to fix this? Some heating on the GPU or something? Or only with a change of logic board will get fixed?
