Cleaning Your TV

Clean your TV regularly to keep it at peak performance and to extend the product lifespan.

CAUTION

yyBefore cleaning, turn the power off and disconnect the power cord and all other cables.

yyWhen the TV is left unattended or unused for a long time, disconnect the power cord from the wall outlet to prevent possible damage from lightning or power surges.

To remove dust or light dirt, wipe the surface with a dry, clean, and soft cloth.

To remove major dirt, wipe the surface with a soft cloth dampened in clean water or a diluted mild detergent. Then wipe immediately with a dry cloth.

CAUTION

yyDo not push, rub, or hit the surface with your fingernail or a sharp object, as this may result in scratches on the screen and image distortions.

yyDo not use any chemicals, such as waxes, benzene, alcohol, thinners, insecticides, air fresheners, or lubricants, as these may damage the screen’s finish and cause discoloration.

yyDo not spray liquid onto the surface. If water enters the TV, it may result in fire, electric shock, or malfunction.
