    Hi,

    Lately my laptop screen has started to flicker.

    It doesn't always happen but from time to time it will happen when I am working on it and I have to move it slightly or tap it. this generally solves the problem. sometimes it doesn't always stop flickering immediately.

    It almost feels like there is some sort of lose connection inside and when it flickers and I move or tap the screen the connection gets reestablished again.

    Has anybody come across anything similar and if so what did you do to resolve it?

    Cheers
    Paul

    This is not an uncommon fault in laptops and the most likely cause is either a loose connection or a failing backlight / inverterboard.

    The majority of the time both of these are relatively easy to fix as long as you don't mind removing a few screws and taking the screen casing apart a little.

    What is the exact make and model of your laptop? There are guides for many of the 'big brand' names on how to do this online.

    Have a look at this, the inverter is certainly where I would start.

    That should help you get to the inverter itself. I would think it likely needs replacing rather than a loose connection.

    Example of replacement inverter from Ebay (UK):

    Amazon:

    Interverters are generally fairly cheap and relatively easy to replace as it isn't uncommon for them to fail as laptops get older. Up to you, but might be worth checking the cabling of your existing inverter incase something has come loose. Just be aware that if it is faulty, fiddling with it might kill it totally so your laptop will be useless from then until you replace the inverter or use an external monitor.

    Google will provide you with plenty of places to buy the inverters.
