ok so the red/black wires are just to power the back-light of the LCD.

i noticed these lines as i had angled the LCD around - no back-light illumination.

I thought to manually power the back-light with a 9v volt battery just to illuminate what the LCD was producing.

Whenever id pull the power from the FDIM but leave the power to the back-light on, the lines would disappear.

So these lines are definitely something that the board is producing.
