6 Software Update Needed

If you can access the TV menus, check if there are any software updates and install them.

7 Check Power Saver Settings

Some TVs come with a sleep timer or power saver feature that will turn off the screen when not in use or at a configured time.

  1. Open up your menu settings.
  2. Find the timer or power save features.
  3. Check to see if they’re turned on. If so, turn them off. And be sure to keep your TV screen clean to ensure that the picture is clear from dirt too.

8 Hard Reset Needed

  1. Press and hold the power button on the remote control for about 5 seconds until the “Power off” message is displayed.
  2. The TV will turn off and then restart automatically after about one minute.
  3. If the problem persists, perform a factory reset within the settings of the TV.

9 Internal Component Failure

Note that this step can be intricate and requires some technical knowledge. You can quickly check for internal component failure by:

  1. Remove the back panel of the TV.
  2. Inspect for any visible damage or loose connections.
  3. If either or both the main and T-CON boards are deemed to be faulty, replace them. These are also solutions in the case that your TV has sound but no picture.
