Galaxy Note 10.1 2014 (P605) LCD Half displaying blank screen

Hi Guys. My Galaxy Note 10.1 2014 P605 LCD screen has completely gone bonkers. The youtube link shows a short video of exactly what is happening. It seems that the touchscreen and buttons all work fine.

I'm curious if this is a bad LCD cable or something else. I've removed and reseated the LCD ribbon cable and after doing so a few times, I get a slightly different result to the screen each time. But never get any better than the video. I either get no screen at all, what you see in the video, or something in between that.

Any thoughts what could be the issue?
