I run a repair shop and replace these frequently, in the last 2 weeks i have had 2 repairs come back doing this exact thing. After RMAing lcd twice, the replacements continue to do this issue. I even ordered one right from here to see if it was a quality difference. My theory is possibly the heat from the motherboard or battery is making direct contact with the back of the lcd panel and causing damage. If i have another like this i am going to insulate the exposed area over the battery with some electric tape to see if it possibly helps, but this is becoming an expensive issue for even myself.
