MAINTENANCE
Picture Screen Cleaning
• If the LCD panel should require cleaning, wipe it with a cotton
or soft cloth. Before cleaning the picture screen, disconnect the
power cord.
Service
• Should your LCD colour TV become inoperative, do not try to
correct the problem by yourself. There are no user-serviceable
parts inside. Turn the unit off, unplug the power cord, and take
the unit to a Service Centre for servicing.
Cabinet Cleaning
• Wipe the front panel and other exterior surfaces of the TV with
a soft cloth immersed in lukewarm water and wrung dry.
• Never use a solvent or alcohol. Do not spray insecticide liquid
near the TV. Such chemicals may cause damage and
discoloration to the exposed surfaces.
