I have a 13.3" Screen It has power and turns on, but the screen flickers and its hard to see the loading screen. But most of the time it works for 3 seconds and the screen turns white kind of slowly. Can anyone tell me what the problem could be? I was thinking of changing the Ribbon cable but I don't know if that could be he problem. The laptop works because I can hook it up to the a monitor and I can do what ever I want.Help me please.
