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 sample picture content and plays sample 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.


    5. Select Start Self Diagnostics.

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

    7. Select Start.



      • The TV will display sample picture content and play a sample audio clip.
      • The audio is played through the TVs built-in speakers. If sound cannot be heard, try adjusting the volume level up using the remote control.


    8. Once the test concludes you can restart the test or exit.


    If you did not observe any problems with the test pictures and sound, the TV is functioning correctly. If you are experiencing picture or audio issues while using an externally connected device, verify the physical cable connection between the TV and the device as well as the external device settings.
