The problem is the laptop display goes white on bootup. Only on pressing the laptop screen hard on the right hand side for a few moments restores the display. Any change to display position causes it again.

It's a Lenovo Z560, and recently i took it company service center who said the problem is not with display or display cable, but with motherboard. I was surprised at the diagnosis, but since i do not have another screen I have no option.

But my question is how is it possible that it's a mobo issue if all i am doing to get the display back ( from full grey and white ) is press hard on the laptop screen.

Any help would be greatly appreciated.( Also i have a desktop display and would checking it with that connection help establish what the problem is?)
