Hello,
In the last couple of weeks I've noticed that the brightness of the screen change back and forth every 1.5 seconds. When the brightness lowers, the screen sort of vibrates and text get a bit blurry. Kind of like you can see in the picture attached to this post, just not that bad. I have no eco settings enabled and Smart LED is turned off.
What is happening to my TV? It's a UN55KS8000 and about 4.5 years old.
