Samsung NP300E5A display vertical lines

[Iersuo]

Hello! I have a Samsung NP300E5A with an LCD display of 15.6" (LTN156AT19-001) where all of a sudden vertical lines appeared. External video displays work correctly, both DVI and HDMI. Is there any way to determine whether the issue is in the video cable or the panel itself? Cost of the panel is so high that it is not viable to change it. The cable on the other hand is very cheap. I took the screen off of the frame to try to flex the cable while it is on, but moving cable doesn't give any effect. Also the lines are always the same, not less, not more.
Thank you for any help!

Unlikely to be cable, sorry, it looks very much like tab bond failure on the screen to me.
Sometimes you can get lucky and apply a bit of pressure in the right place and it will disappear. Be careful though.

Good work, its the address driver packs that are responsible for addressing the rows pixels. Each row has two transistors in the Ic, looks like a few of the transistors for the green sub-pixel rows inside the Ic shorted and caused them rows to be stuck open and you get stuck lines.
