    My screen has started being covered by vertical coloured lines periodically. I can get rid of them by wiggling the whole upper display, which makes me think it is some kind of connection problem. I'm comfortable opening up my macbook and tinkering with it, but I wanted to get some feedback before I start.

    Here's what the lines look like:



    And here is a video that shows how the lines appear and disappear:

    As you can see, the colours of lines correlate to the image on the screen at that point.

    I've tried searching for this problem, but cannot find anything. If you have any idea what could be causing this, please let me know.

    Must be a connection issue. Seems like something is "pinching the cable" when the hinge is moving.

    That's all I can say. I have no experience in repairing that stuff but pretty sure it's the cable linking the screen to the logic board that's at fault.

    adnbek is most likely correct. There is a cable in the hinge that can become pinched or worn over time because it is being moved every time you open and close the display. Replacement cables are sometimes available on ebay or powerbookmedic, they also have videos at powerbookmedic on how to open the case on most models of macbooks, check those out and see if the cable is damaged.
