On start up when cold get white bar across page with vertical lines
On start up of my 13” mid 2012 MacBook Pro I get a white bar across screen with vertical lines down.
This can generally be fixed when I warm the base of the laptop and jiggle the screen. The lead to the screen has been replaced (which I’ve done).
I’ve tried everything I can think of! Sometimes I have to keep jiggling the screen to keep it from fading but other times, when the day is warm, it is OK till I leave it for a while and then the whole thing happens again.
Any thoughts? Must be temperature related.
Could be your GPU which is having issues. But I'm not for sure. Could you test it ? Perhaps someone else here recognize this.

Can you tell us which system you have?
◆ 13" MacBook Pro Unibody models
◆ 13" MacBook Pro Retina models
They are radically different!
Can you give us some background on your system did you have a liquid spill or sit it down on a wet surface at some point?
What happens when you use an external monitor is the image OK on it?
