MAINTENANCE
Cleaning your TV
Clean your TV regularly to keep the best performance and to extend the product lifespan.
CAUTION

Screen, frame, cabinet and stand
yy To remove dust or light dirt, wipe the surface with a dry, clean, and soft cloth.

mild detergent. Then wipe immediately with a dry cloth.
