Lines on the screen and then strange color

[Wenjie_Cai]

Hi! My screen shows vertical lines 1 month ago for 2 days and they disappeared. But the lines appeared again today and the whole screen turned into strange color of dark blue though I can still see everything on the screen. Would you mind helping me with this issue? I am wondering if it is a hardware issue and where I should go to fix it. Thanks!

Welcome to the HP support community.

I understand that you are getting issues with the notebook display, I am glad to assist you.

If you haven't, Please try an alternate monitor to understand if this is either a hardware or a software failure, 

if the issue does not appear on the alternate monitor, you may need to replace the display assembly on your computer, 

if the issue appears on the alternate monitor/TV as well, re-install the graphics card drivers & update it from the official HP Website: Click here 

If you don’t have an alternate monitor, I recommend checking if the issue appears on the BIOS screen (restart the computer and tap on F10 to access BIOS) 

If the issue does not appear in BIOS, reinstall the graphics card drivers & update BIOS using the above link, 
If it does, you may need to replace the LCD/Repair the computer: 

Keep me posted.

If this helps, please mark the public post as an accepted solution so that it benefits several others.

Cheers.
