Hello. Has anyone had this happen? First I had one black line, then two, then more, now about half of it is this way. I've pulled the panel and cleaned and checked all of the ribbon cables and connectors. On the back of the display are a bunch of bent metal tabs which look to make contact with ground pads on the display module. I gave each of these a small check with some pliers, no change. Time to order a replacement module from Epilog?
