How to use the Self Diagnostics option

    The Self Diagnostics option briefly checks the TV for proper functionality by running two basic tests: Self Diagnostics, which runs an internal system self-check test, and the Check Sound/Picture test, which displays a sample picture and audio clip.

    NOTE: For details on how to start the Self Diagnostics test, see the operating instructions supplied with the device.

    The following is one example of how to start the Self Diagnostics test:

    1. Press the Home button.
    2. Select ?/Help located in the upper-right corner on the TV screen.
    3. Select Customer Support.
    4. Select Self Diagnostics.
       Select Self Diagnostics
    5. Select Start Self Diagnostics.

        Start Self Diagnostics
    6. If no error is detected, select Check Picture/Sound to continue.

    7. Select Start.

      Check Picture/Sound 

      NOTE:

      • The TV will display a sample picture and audio clip.
      • The audio is played through the TV's built-in speakers. If sound cannot be heard, try increasing the volume using the remote control.

    If there were no issues during the test, the TV is functioning correctly. If you are experiencing picture or audio issues while using an externally connected device, verify the cable connection between the TV and the device, and then check the external device's settings.
