While it sounds like a connector connection issue, since you didn't use this clue to do the work then it's back to the camera maker to tell you how much to fix it. I never write about DIY repairs since it's an area that you either do this or you don't and you accept that it may not work out.
I have a Sony Cybershot DSC-W180; the screen intermittently goes blank (white/grey) with a vertical line down the centre, particularly when I press any buttons. The image comes back if i apply pressure to the bottom right of the screen. Anyone know if this is a fixable issue?
