HP Spectre x360 15-eb1043dx LCD issue - vertical lines

[Cambrias]

Hello, 

Suddenly, my computer started showing vertical lines last night. There was no trauma prior that I can think of that caused this. Mostly, when the computer starts up, the lines are super white and they fade slowly after a few mins. Some lines can be 'erased' in a way by moving my cursor over them. The lines like to show up after white pixels are on the screen, since at boot a white screen flashes before my screen loads.

What I've done thus far to no avail:

- update all drivers

- uninstall and reinstall graphics driver

- update windows 11

- try a hard reset

- squished screen and gone between tablet and computer mode and nothing affect the lines

- plugged in external monitor via USB-c -> shows perfect ( no vertical lines)

The only thing to seemingly affects the lines is the colors shown on the screen. Please help with maintenance ideas or links.

I have the exact same issue in EVERY regard. @cambrias I see you have no replies, but have you had any insights or luck based on all of your research?
