It could be your current problem, but it is not the problem causing the lines. You can send the main board to us and we can test it and see how it behaves, possibly fix it, but we likely won't be able to take care of those lines.

See if you can change the input. and see if it is any better. If not there may be something loose internally. I don't recommend attempting to repair yourself, but having a tech do it can be pricey. Try and leave the TV off for 24 hours and trying again, if it persists you may need to replace the TV. Good luck
