Laptop's IPS screen has vertical & horizontal lines.

Hi, I have razer blade 15 base (2021) with IPS screen and it got vertical and horizontal lines. there are one vertical and one horizontal line which are changing color and also several dimmed horizontal lines on 50% of screen which are flickering when screen is showing video.

sometimes area gets bigger like this and sometimes they disappear. (this is a picture while I was running jscreenfix)

Also screen has some electrical sparkle noise on the bottom.

I may be wrong, but intuition tells me that there is no physical damage, because it didn’t experience drop and I was more gentle with closing/opening than while removing tape during disassembling(I even have bent it a little and it didn’t added any new damage). So, before I buy replacement, what problems there may be besides of physical damage and how can I fix them?

Also I would appreciate to know if it’s possible to replace with QHD 165 HZ panel (currently I have FHD 144HZ)?
