Maintenance Troubleshooting First, unplug the power cord plug from the wall outlet. Power cord plug Wipe the plug with a dry cloth at regular intervals. (Moisture and dust can lead to fire or electrical shock.) Display panel The front of the display panel has been specially treated. Wipe the panel surface gently, using only a cleaning cloth or a soft, lint-free cloth. ●If the surface is particularly dirty, soak a soft, lint-free cloth in diluted, mild liquid dish soap (1 part mild liquid dish soap diluted by 100 times the amount of water) and then wring the cloth to remove excess liquid. Use this cloth to wipe the surface of the display panel, then wipe it evenly with a dry cloth of the same type until the surface is dry. ●Do not scratch or hit the surface of the panel with fingernails or other hard objects. Furthermore, avoid contact with volatile substances such as insect sprays, solvents, and thinner; otherwise, the quality of the surface may be adversely affected. Cabinet If the cabinet becomes dirty, wipe it with a soft, dry cloth. ●If the cabinet is particularly dirty, soak the cloth in diluted, mild liquid dish soap and then wring the cloth dry. Use this cloth to wipe the cabinet and then wipe it dry with a dry cloth. ●Do not allow any mild liquid dish soap to come into direct contact with the surface of the TV. If water droplets get inside the unit, operating problems may result. ●Avoid contact with volatile substances such as insect sprays, solvents, and thinner; otherwise, the quality of the cabinet surface may be adversely affected or the coating may peel off. ●Do not let articles made from rubber or PVC be in contact with the TV for long periods of time. Pedestal ●Wipe the surfaces with a soft, dry cloth. If the unit is particularly dirty, clean it using a cloth soaked with water to which a small amount of mild liquid dish soap has been added and then wipe with a dry cloth. Do not use products such as solvents, thinner, or household wax for cleaning, as they can damage the surface coating. (If using a chemically-treated cloth, follow the instructions supplied with the cloth.) ●Do not attach sticky tape or labels, as they can make the surface of the pedestal dirty. Do not allow longterm contact with rubber, vinyl products, or the like. (Doing so will cause deterioration.)

Why is the picture snowy when [ANTENNA/Cable In] is selected?  When using a cable service (without a box), check that all connections are secure.  When using a cable or satellite box, change the connection to COMPOSITE, COMPONENT or HDMI (p. 11-12).  If you're using an antenna, then check that connections are secure. Change the position or direction of the antenna and check the [Signal meter] (p. 14). Maintenance | Troubleshooting 28 English
