Maintenance DX-55L150A11 17 General Problem Solution One or more channels do not display. • Make sure that the channels are not blocked. For more information, see "Setting parental controls" on page 14. Password is lost. • Enter 9999 to access parental controls, then set a new password. For more information, see "Setting parental controls" on page 14. Some settings cannot be accessed. • If a setting is grayed, the setting is not available in the current video input mode. TV cabinet creaks. Control buttons on the TV do not work. • When the TV is in use, the temperature rises naturally and may cause the cabinet to expand or contract which can cause a creaking noise. This is not a malfunction. • Disconnect the power cord, wait a few seconds, then reconnect the power cord and turn on the TV. Note: If the problem is not solved by using these troubleshooting instructions, try turning off your TV, then turning it on again. Maintenance Just like with any other household appliance, the performance and life-expectancy of your TV depends on how well you maintain it. Follow the procedures described here to clean the TV case and the LCD screen. Cautions: • Make sure that the TV is turned off and the power cord is disconnected from the power outlet before cleaning the TV. • Never spray or pour any liquid directly onto the screen or the case. Cleaning • Clean your TV with a soft, dry cloth. If surfaces are extremely dirty, use a soft cloth dampened with a small amount of non-ammonia, non-alcohol-based, non-abrasive detergent solution. • Clean the screen with a clean, soft, lint-free cloth. If additional cleaning is necessary, apply a small amount of non-ammonia, non-alcohol-based, non-abrasive detergent solution to the cloth.
