Your lines are really not exclusively horizontal. There are more vertical lines which could be caused by loss of timing. This could be a bad T-con board, bad main board or at worst a bad panel. Remove the back and take a look at the boards and the wiring. Post some images of those with your question. That will allow us to see what you see . T-con board would be my first suspect.
