Troubleshooting DX-42E250A12
Remote control
General
Poor picture • Make sure that the room is not too bright.
Light reflecting off the screen can make the
picture difficult to see.
• 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.
Good sound but
poor color • Adjust the contrast, color, and brightness
settings.
Audio noise • Other devices (for example, 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 the TV to eliminate the
interference.
No output from one
of the speakers • Adjust the audio balance. See “Adjusting
sound settings” on page 18.
• Make sure that the audio cables are
connected correctly and securely to the
back of your TV.
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.
