Compaq CQ50-139WM / Windows Vista Home
Hi guys, I am somewhat of a novice when it comes to computer repair but I am a professional tinkerer (lol). I have this laptop that has a video issue. When I turn it on it starts flickering right away, with all kinds of horizonal lines, then it straightens out but it freezes. then it starts fading to white while still frozen. Whe I connect to an external monitor all is fine. What could the problem be? Thanks for any help.
