Laptop screen turns white with vertical lines on max brightness

shanechristophersinnerine · Jul 12, 2018

I have a Lenovo yoga and was watching a youtube video which happened to have alot of bright white in it. Right after watching this video, if my screen is on max brightness and I open any page with alot of white, it will show only vertical white lines. Is there any easy solution to this?

Did you try restarting the laptop to see if that resolved the problem? Sometimes that is all you need. If that doesn't do it, then try the following...

1. Turn the laptop off (not sleep or hibernate but off).
2. Connect an external monitor to the laptop.
3. Turn on the external monitor.
4. Turn on the laptop.

NOTE: You may have to press an "external monitor" button. Could be the f4 button or a button with two monitors on it, for the external monitor to work.

If you can see fine on the external monitor, then your attached display, or the ribbon cable that connects it, are your problem.

If you can't see on the external monitor at all, or the problem occurs on the external monitor as well, then it is probably the graphics card/GPU that is the problem, which may require the motherboard be replaced.
