HP Omen LED 4k display strange red areas and half a line of scratch like

[questore]

Hi Everyone,

I have brought to you a strange problem display maybe you have some ideas how it can be fixed or what could cause such a problem.
Display Type: B173ZAN01.1
MANUFACTURER: AU Optrinics
H/W:0A F/W:1

Changed the cable and tried to bend, push the back f the screen and both problem persists, nothing changes.
There is no any sign that the back of the screen was under pressure, or has moving cables.

PROBLEM 1:. Red spots / area in the screen
MORE INFO: If i gently press above the problematic area then it disappears until pressure applied. (Problem only visible if screen area has dark content.)


PROBLEM 2: A Horizontal half black line that starts from the left of the screen and slowly getting smaller until it disappears abouth 1/3 of the screen.
MORE INFO:
- Only visible if screen has not dark content on that area.
- No scratch on the front or back of the screen, I have even checked it with microscope.
- If moving content is on the screen then the line pixels starts to vibrate like moving pixels dancing in the line.


Any idea how to fix these or what cause them?
