MAINTENANCE
Cleaning Your TV
Clean your TV regularly to keep it at peak performance and to extend the product's lifespan.
CAUTION
• Before cleaning, turn the power off and disconnect the power cord and all other cables.
• When 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.
Screen, Frame, Cabinet, and Stand
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
• Do 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.
• Do 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.
• Do not spray liquid onto the surface. If water enters the TV, it may result in fire, electric shock, or
malfunction.
Power Cord
Remove the accumulated dust or dirt on the power cord regularly.
