tvs have a very complex system inside, when a component goes bad many times they will fire up until they get hot and then quit working, it takes a professional to fix in most cases. you can search you tube for this model and see if anyone has posted a repair for your problem but if you don't know how things come apart or how to solder etc it is best to let a professional repair it or get a newer set

First try to gently push the cable between the main board and the LCD controller (T-CON) board and if that doesn't affect the image then replace the T-con board.

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
