Laptop screen stops working after 20 min of use, and so does external screen

  1. Hello, wondering if anyone can offer any advice please
    Having a strange problem with my laptop screen. It's a Tiny 8399 laptop.
    When I start the laptop up, it works fine, but after being on for a while, suddenly the screen goes very funny, with lots of lines - it gets worse and worse until it's totally unusable. Moving the screen changes the picture slightly but doesn't help. Then when I turn back on again it's OK again.
    What is really strange is that last time I turned on my laptop I connected an external screen. At first both screens worked fine, then after about 15 minutes the laptop screen went funny as described, but the external screen went blank! So seems like it may not be the screen, but perhaps the grahpics card...? Or something else I don't know. But it's weird that when I move the laptop screen when this is all happening the picture does change slightly.
    Any advice would be appreciated.

    Sounds like a faulty card or cable, if your able strip the laptop down and find the cable that links the screen to the motherboard, it may be loose, if the graphics card is a plug in type then try reseating it.

    Other than that your gonna need a visit to a pc shop....
