Problem with artifacts on Pandaboard ES

UPDATED 3-Jul-2012 with more simple instruction, thanks to our customer Mark!

Some of our customers found that running our v2 board on Pandaboard ES gives some artifacts on LCD picture. You can notice on below photo that pixel rows are shifted on contrast areas (black text on white background).

The same board has no artifacts running on Beagleboard, Beagleboard-xM, and original Pandaboard. To solve this problem you have to remove resistor R85 on PandaBoard-ES (second counting from the bottom in block C) and put 0 Ohm resistor or just put solder drop to short both pads.

That’s all, now artifacts should gone and you will have clear picture on Pandaboard ES.
