Image On Laptop Screen Freezes And Slowly Turns White

Problem description:

Spontaneously the laptop screen will “freeze” the current image and then slowly turn white with some faint gray blotches. If I move the top of the laptop toward me, sometimes the image comes back to normal. If I move it backward, then the image freezes and goes white again. The laptop works fine with the external monitor.

Possible cause:

1. Bad connection between the video cable and LCD screen.
2. LCD screen failure.

Possible troubleshooting steps and repair solution:

First of all, try reconnecting the video cable on the back of the LCD screen. It’s possible that the video cable is not making good contact with the LCD screen.

If reconnecting the cable doesn’t help, most likely this is an LCD screen failure. Apparently, there is a faulty component or solder joint on the screen controller board. In this case, the LCD screen has to be replaced with a new one.
