Maintaining your television
To clean your television screen:
1
Unplug your television to avoid possible
shock hazard.
2 Use a damp cloth or clean cellulose sponge
to clean your television screen and trim. Do
not let water spill into the cabinet or damage
may occur.
3 Wipe off any 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.
Troubleshooting
The most common types of television
interference are as follows:
Warning
Television sets use high voltage. Do not try to remove the back
of the cabinet yourself. There are no user serviceable parts
inside. Opening the cabinet could void your warranty. Refer
servicing to qualified service technicians.
Caution
Never use strong solvents (such as thinner, benzene, or other
chemicals) on or near the cabinet. These chemicals can
damage the cabinet finish.
Notes
• If your television does not operate as expected, unplug the
power, then plug it back in.
• Displaying a still picture for a long period of time will cause
the image to “stick” if the input signal is interlaced. The
stuck image disappears when you briefly turn your
television off.
Problem Solution
Snowy picture • VHF/UHF: This is
usually caused by a
weak signal. Adjust the
antenna or install an
antenna amplifier.
Double image or ghosts • VHF/UHF: This is
usually caused by
reflections from a tall
building. Adjust the
direction of the
antenna or raise it.
Radio wave interference • VHF/UHF: This is
usually caused by
nearby radio
transmitters or
shortwave receiving
equipment.
High-temperature
electrothermal interference • VHF/UHF: This is
usually caused by
high-temperature
electrothermal
equipment in a nearby
business.
