Maintaining • Do not use your TV in areas that are too hot or too cold, because the cabinet may warp or the screen may malfunction. Your TV works best in temperatures that are comfortable to you. • Storage temperatures are 32° to 122°F (0° to 50°C). • Working temperatures are 41° to 104°F (5° to 40°C). • Do not place your TV in direct sunlight or near a heat source. Cleaning the TV cabinet Clean the cabinet with a soft, lint-free cloth. Do not use the cleaning cloth that came with your TV to clean the cabinet. If the cabinet is especially dirty, moisten a soft, lint-free cloth in a weak detergent solution, squeeze the excess moisture from the cloth, then wipe the screen or cabinet with the cloth. Use a clean cloth to dry the screen or cabinet. Cleaning the TV screen Clean the screen with the cleaning cloth or a soft, lint-free cloth. Do not use the cleaning cloth to clean other parts of your TV. Troubleshooting Warning Do not try to repair your TV yourself. Refer all service to a qualified service technician.
