I have a MacBook Pro 15" model A1226
Takayazhe problem as the video:
If you squeeze the frame with your fingers right at the place where the gray area starts, the problem disappears and in the process does not appear (somewhere there is a contact vidimi). Appears again after close/open laptop, but not always.
PRAM reset did not helped...
PTS want to hear the opinions of people and our service will immediately start to change everything starting from the motherboard, video card, screen and finishing with all buck.
Anyone faced with such problem and knows as to treat?
