Vertical Red/Green lines

After my 43H71 is on for about 30 minutes, red and green lines begin to appear at 1/3 and 2/3 on the screen. At first, it's just a few pixels along these lines. As time goes by, more and more dots appear along these lines until they are almost solid (about after an hour of the TV being on).

I've done the touch focus auto convergance, but I don't know what else I can do.

I just recently move the TV across the city, and the problem was not present before the move. (We were careful, and didn't hit any big bumps or anything....)
