I have white screen on my laptop as soon as I hit the power button. I have replaced LCD, RAM, HDD and video connector cable and still left with same issue. The display works perfect if I plug in an external monitor. I am at a complete loss on this and could really use some help. What am I missing here?
Sounds like the screen was replaced improperly or the wrong part was used. If it works with an external monitor you did not have to replace anything else.
Screen was installed properly I had the white screen before and that is why I changed the screen,. I thought maybe the screen was bad. New screen does the same thing as soon as I hit the power button it comes up solid white. I thought maybe the video connector was bad since it was working on external monitor so I replaced that as well but still ended with same result. I had read that bad ram could do this but after replacing both ram sticks I still had the same white screen. Then I read about a white screen virus so I scanned the hell out of it with every thing I have and didnt find anythig. Just replaced the HDD to rule it out. Reinstalled windows 7 using the external monitor, rebooted without the external and damn if the screen was still white! I am lost at this point..
