    Self-Diagnosis Screen Display
    For failures that are difficult to reproduce, or accompany occasional power off and/or picture mute, the Self-Diagnosis screen display is useful to specify the cause..

    To Bring Up Screen Test

    In standby mode, press the buttons on the Remote Commander sequentially, in rapid succession, as shown below:

    DISPLAY --> Channel 5 --> Sound Volume [-/volume down] --> POWER

    It will display a screen display like the one below or similiar to it.  The numbers to the left are the blinking lights and the abbreviation to the right is that issu that your TV has.

    Since the diagnostic results displayed on the screen are not automatically cleared, always check the self-diagnostic screen during repairs. When you have completed the repairs, clear the result display to “0”.

    Clearing the Result Display

    To clear the result display to “0”, press the buttons on the Remote Commander sequentially when the diagnostic screen is displayed, as shown below:
    1. If the screen is already displayed, proceed to step 3. If not, Power off (Set to Standby mode).
    2. Press DISPLAY --> Channel 5 --> Sound Volume - --> POWER
    3. Press Channel 8 --> ENT
    Clearing the Self-Diagnostic Screen
    The self diagnosis screen display is cleared
