I have an aspire one kav60. There seems to be a bad screen contact in the left hinge. At times the screen will flicker rapidly, as if the image is rolling at high speed. If I put pressure on the left hinge, from back to front, and from right to left, the problem will go away for a while. If I plug in an external monitor there is no problem. It's only when I use the netbook monitor. Also, if I just let it sit it will sometimes stop on its own. Is there a way to clean the hinge contact? Thanks.
