Mackie Control Universal LCD Screen problem please help

[trashdinner]

Hey guys, I have a Mackie Control Universal Midi controller and the last 15 x 2 squares of my LCD screen is acting weird.
Sometimes it's blank, sometimes the correct text appears and scrolls to the right after a little while, sometime I see lines going down in the squares ...
Here's a link to a video of the screen acting weird and the Schematics: https://www.sendspace.com/file/ck4eht
I would really appreciate your help!
Thank you so much!
