    Hi, I have an acer aspire 7720. On start up I get a white screen, it dissapears if I bump it a few times so it seems to me something is loose. I have opened it up, taken out the keyboard, taken off the LCD and then replaced making sure everything was well pressed down. The fault is still there but not as bad.
    Any suggestions?

    Welcome to TSG!!

    How far did you disassemble the LCD? There is a cable that plugs into the back of the screen itself that is normally held in place by some tape. Try to reseat the end that plugs into the Main Board first. It's easier to access. If that doesn't help, and you are feeling adventurous, you can try to reseat the plug on the rear of the LCD panel.

    It's possible that it is the panel itself that has the loose connection. That's not a home repair ...

    Good luck!

    Thanks, I've disconnected the LCD and taken off the plastic front, then reassembled. Problem still there. Do I have to go further?

    Have you reseated the cable that plugs into the back of the LCD panel itself? It's a flat ribbon cable with a connector on the end.
