I got a LG 42LD450-UA with the worst case of lightning damage I've ever seen. The main board was absolutely toast. The lightning came in through the composite inputs and took out those circuits, the main board was a total loss. I replaced the main board with a compatible one, but now every other column is red. It seems too consistent to me to be a panel fault, at first I thought it was incorrect firmware, but after checking the INSTART settings and force flashing the latest correct firmware using the wonderful resources at http://openlgtv.org.ru/, the problem still persists. At this point I am wondering if a failed TCON board can cause this, or perhaps a faulty connection between the TCON and the main board. Any insight is appreciated, thanks
