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, mild, non-abrasive detergent.

•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 glass cleaner onto a clean, soft, lint-free cloth, then wipe the screen.
