When I start my laptop the display is completely white. Displays properly on an external monitor. I had everything apart and reattached the cables. When I push on the corner of the motherboard it displays fine. Can I assume the motherboard is bad?

I did replace the motherboard, but I have the same issue. Even replaced the CPU. It does not seem to be the video cable, when I wiggle it nothing happens.
