•  No power

•  Check if you pressed 

POWER on the remote control unit. (See page 

    19.) If the indicator on the TV is still red, press 

POWER on the TV. 

•  Is the AC cord disconnected? (See page 8.)

•  Has the power been turned on? (See page 19.)

•  Unit cannot be 
    operated.

•  External influences such as lightning, static electricity, may cause 

    improper operation. In this case, operate the unit after first turning 

    off the power of the TV or unplugging the AC cord and re-plugging 

    it after 1 or 2 minutes.

•  Remote control unit 
    does not operate.

•  Are batteries inserted with polarity ( +, - ) aligned? (See page 10.)

•  Are batteries worn out? (Replace with new batteries.)

•  Are you using it under strong or fluorescent lighting? 

•  Is a fluorescent light illuminated near the remote control sensor? 

•  Picture is cut off/with 

    sidebar screen.

•  Are screen mode adjustments such as picture size made correctly? 

    (See page 23.)

•  Strange color, light 

    color, or color 

    misalignment.

•  Power is suddenly 

    turned off.

•  No picture

•  No sound

•  The TV sometimes 

    makes a cracking 

    sound.

•  This is not a malfunction. This happens when the cabinet slightly 

    expands and contracts according to change in temperature. This 

    does not affect the TV’s performance.

•  When the unit is used in a low temperature space (e.g. room, office), the picture may leave 

    trails or appear slightly delayed. This is not a malfunction, and the unit will recover when the 

    temperature returns to normal.

•  Do not leave the unit in a hot or cold location. Also, do not leave the unit in a location exposed 

    to direct sunlight or near a heater, as this may cause the cabinet to deform and the Liquid 

    Crystal panel to malfunction. 

    Storage temperature: -4°F to +140°F (-20°C to +60°C)
