No impact in Notebook, but vertical lines appeared in display whatsoever

[cobainnn]

Hello. I'm a HP Omen 15 user, bought this laptop in 2019. Laptop received no impacts ot any other damages so far, but yesterday i've encountered to have vertical lines all of a sudden. Here's how it looks like: 

I've tested the issue by Hp Hardware Diagnostics, two interesting things had appeared:

- Right after opening the Video Palette Check, the lines suddenly disappeared. And after it's done, the lines came back again.

- In the Dead-Pixel test, the lines only show itself when Blue screen covers the entire screen, by making that portion of screen a little bit darker than normal.

Before going to any technical service, i thought of controlling the hardware myself by disassembling it but i have little idea about where to check inside (i've opened the laptop before several times, i only don't know what to do to check display issue don't get me wrong).

Any suggestions?

The documents did not really help.

The vertical lines doesn't seem to disappear by moving it or snapping various areas in the display. However, when opening the Laptop, the display often resets itself several times before i can move on to the desktop. I take it as a problem of display panel cable where it might've moved from it's place a little, but maybe i'm just wrong. I'd like to see my alternatives before i check it.
