Why the display is gray with vertical lines

I have unique video of my display destruction: https://www.youtube.com/watch?v=ync-2kJZ...

Service Tag: 7JDRH12

I tried to reconnect all cables in display and to motherboard (hoped for bad connection), but nothing…

Just a thought, maybe the inverter board is loose/bad. That is something that you can look into. I've also seen bad RAM cause screen/resolution issues.
