Remote control
Poor picture
Light in the viewing area
may be interfering
• Make sure that the room is not too bright. Light reflecting off
the screen can make the picture difficult to see.
A connected camera or
camcorder may be
interfering
• If an S-VHS camera or a camcorder is connected while another
connected device is turned on, the picture may be poor. Turn
off one or more devices.
Audio noise
Other devices may be
interfering
• Other devices (for example, a surround sound receiver,
external speakers, fans, or hair dryers) may be interfering with
your TV. Try turning off one device at a time to determine
which device is causing interference. After you have
determined which device is causing interference, move it
further from your TV to eliminate the interference.
After images
appear
• Do not display a still image, such as a logo, game, or computer
image, for an extended period of time. This can cause a
permanent after-image to be burned into the screen. This type
of damage is not covered by your warranty.
