Friend do not comment on the TV model, in any case this usually happens when there are bad LEDs, you must uncover the TV, lift the screen very carefully and check the LEDs, to confirm that you have bad LEDs it is best to replace them all, they have limited shelf life and if some have already failed some others are close to fail too, it is a better guarantee. Greetings and luck
