Someone tell me what these lines are on my TV? I don’t believe it’s a signal issue because it appears on the TV when the FiOS box isn’t. TV was bought in July.
Brent Bryan that is s bad screen. It will not get better with age and since this is a relatively new TV it should still be covered under warranty. Make use of it and replace your TV. They may recommend a repair and might want to change the mainboard first but ultimately it looks like errors from the LED driver board.
the tv screen might be broken or no service
