Cleaning and care
WARNING: TV sets use high voltage. Do not remove the cabinet back.
Refer all servicing to qualified service technicians.
To clean the TV screen and cabinet:
1. Unplug the power cord to avoid possible shock hazard.
2. Use a clean cellulose sponge or chamois cloth dampened with a solution of mild detergent and warm water
to clean the TV screen and trim. Do not use too much water; liquid spilling into the cabinet can damage
the TV.
3. Wipe off excess moisture with a clean dry cloth.
4. Polish the cabinet with a quality furniture polish to maintain the finish and appearance of the cabinet.
Caution:
Never use strong solvents such as thinner, benzene, or other chemicals on or near the cabinet.
These chemicals can damage the cabinet’s finish.
