Display flickers hi my display gets this flickering horizontal white lines which gets fine on moving the display slightly but then again develops, started a month ago was fine in between for 15 days started having this problem again. it works well on external display, how do i figure out if it is cable problem or lcd display is broken

Hi, Check all your connections are fitted properly it could be a faulty wire if you can try another wire then do so & see if that solves the problem. The only other thing it could be if you had your machine apart & maybe the video card is not pushed right into the slot look for the small white clip that clips into the rear of your PC inside the machine. If none of this works then I suggest your video card is no longer working properly so you need a new one. Please leave me feed back: Malcolm Campbell, Thanks.
