Troubleshooting
Cautions regarding use in high and low temperature environments
• 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 LCD panel to malfunction.
Storage temperature: –20°C to +60°C (–4°F to +140°F).
• No power.
• Unit cannot be operated.
• Remote control unit does not
operate.
• Picture is cut off.
• Strange colour, light colour, or
dark, or colour misalignment.
• Power is suddenly turned off.
• No picture.
• No sound.
