Hey everyone. I'm having some hardware issue with my display. When I turn the computer on, the bottom quarter of the screen becomes bars of a rainbow of colors while the top 3/4 remains just fine. I can fix this only if I push the left side of the display a little past where it should be (and hold it there). Do you think this is a problem with the display cable or the display itself? I'm planning to just buy the part and fix it myself.
