Leaving the TV on all night affects the TV and the person sleeping with the TV.

The production of melatonin by the brain, which happens at night, gets distracted when you sleep with the TV, making it difficult for the brain to know whether it’s day or night.

Also, not only at night but leaving the TV on for long hours, be it during the day or at night, can cause image burn if the screen saver is not enabled.

The image left behind is what we term image burn. What always saves the screen anytime it gets stuck at a still image is a screen saver.

Once a screen saver is enabled on the TV, it takes over when the still image displays for a specific set duration. This will help prevent any image burn.
