Vertical white line in lcd

[Bzn]

I got a Notebook Pavilion 15 Notebook PC p189sa. In teh days of hot weather, suddenly the lcd displayed white vertical lines and the different lines became separated.

I changed the cable conecting the mainboard with the lcd and nothing improved with the new cable.

A new monitor conected by VGA is working perfectly well.

Drivers and BIOS have been updated without improvement.

I run the HP Hardware diagnosis tool. All systems are ok, but the Video memory fast test andf the Video extended memory check are cancelled. No error code is given. All the remaining test Passed.

Can you help me to detect what part is faulty please?

Thanks

Hey there! @Bzn, Thanks for stopping by the HP Support Forums!

I understand you have display issues with your laptop and you see white vertical lines on the screen.

Don't worry I'll try to help you out.

Did you make any software or hardware changes on your PC?

Does the issue persist in BIOS?

Please share the product number of your PC to assist you better.

As you mentioned the external monitor is working fine. It could be an issue with the display raw panel or the LCD cable which has gone faulty.

If the issue does not persist in BIOS try updating the graphics driver and BIOS on your PC.

You can try updating the drivers on your PC using HP support assistant.

Also, try restoring the BIOS to default and check if it helps.

1.    Turn off the computer and wait five seconds.
2.    Press the Power button to start the computer and repeatedly press the F10 key to enter the BIOS setup menu.
3.    On the BIOS Setup screen, press F9 to select and load the BIOS Setup Default settings.
4.    Press F10 to Save and Exit.
5.    Use the arrow keys to select Yes, then press Enter when asked Exit Saving Changes?
6.    Follow the prompts to restart your computer.

Try running a system diagnostics test on your PC and check if the hardware components on your PC are functioning correctly.
