    Hi I have a lenovo g500 laptop running windows 10. It has recently started giving me a white flashing screen with bits of grey and vertical lines. It stays on and does not flicker.
    I have to turn off the laptop to get the screen back to normal. Moving the screen back and forth doesn't influence it in anyway and all display drivers are up to date.
    I have ran a hardware scan (with the lenovo solution center) on the graphics chip and it passed.
    The graphics chip is an intel hd 4000.
    What could be causing such an issue?
    Cheers

    Do you get the same display problems on an external Monitor connected to the laptop ?

    Unfortunatley this is something I'll have to try next time it happens. If it is the same on the external monitor would this suggest the graphics chip on it's way out or something else?

    If the external Monitor shows the same fault then the problem is in the graphics circuitry.

    If the external display is fine when the laptop's is showing the problem then the graphics chip is probably ok and the problem is either the cable between the motherboard and the screen has worked loose from a connector (usually the one on the screen) or the cable is damaged (unlikely in this case since moving the screen doesn't change anything) or the screen itself is damaged.

    I think you're best bet would be to dismantle the laptop yourself, if you feel confident you can do that, and check the cable itself and it's connections at both ends.
    The first video shows how to get at the cable behind the screen, the 2nd video is a complete dismantle of the laptop. Have a look at them and let me know if you want to try doing it yourself.
