Disable Sleep Mode in the Smart TV

Standby mode has become a useful feature on Android TV. Millions of TV owners leave the unit turned on for hours, even when it’s not in use. The sleep timer assists the owners in saving money on electricity bills by turning off the display after one minute to thirty minutes of inactivity.

Display Panel Failure

My Smart TV had a black screen issue a few months back. The TV display panel reached its life cycle end. I will share instructions to identify the panel failure in your Insignia unit. We should test the display in the second self-test.

a. The LED TV dies slowly and takes less than a minute.

b. Ask your family members if the TV displayed brusque lines.

c. Discoloration.

One of the symptoms indicates display failure. My Smart TV had brusque lines before the signs of life went out. We purchased a new TV since the repair cost was not worth it.
