ONN TV won’t Turn on (How to Fix)

If your ONN TV won’t turn on, there are a few common reasons why this might be happening.

Possible reasons include:

  1. The power supply might be faulty.
  2. Issues with the power board or mainboard.
  3. The TV might have encountered a temporary glitch.
When your ONN Roku TV suddenly stops working and refuses to turn on, the typical solution is to replace the board.

However, before you jump to replacing parts, try these simple troubleshooting methods:

  1. Power Cycle the TV: Unplug the TV from the power source and wait for a few minutes (3-5 minutes should be enough). Then, plug it back in. This can sometimes reset the TV and fix the problem.
  2. Inspect the Standby Light: Check if the standby light on the TV is on. If it’s off, the TV might not be receiving power. If it’s on, there could be an issue with the TV’s backlight or mainboard.
  3. Check the Power Source: Make sure the TV is properly plugged into a working power outlet. If possible, try plugging the TV into a different power outlet to rule out any issues with the current one.

If the TV still doesn’t turn on after trying these steps, it may require professional repair.

You can even contact ONN customer support or a certified technician for further assistance
