Troubleshooting

If you have any problems, read this manual again and
check the countermeasure for each of the symptoms
listed below.
If the problem persists, contact your nearest authorized
service center or dealer.
Snowy picture
Noisy sound
/ Check the antenna.
/ Check the antenna connection on the TV
and on the wall.
/ Check the TV SYSTEM setting.
Dotted lines or stripes
/ This may be caused by local interference
(e.g. cars, neon signs, hair dryers, etc.).
Adjust the antenna for minimum
interference.
Double images or "ghosts"
/ This may be caused by reflections from
nearby mountains or buildings. A highly
directional antenna may improve the
picture.
Notes
• When you switch on the TV, you may hear the "boon" sound
that is caused by the demagnetization of the TV. This does not
indicate a malfunction.
• The picture color may become abnormal if you change the
direction of your TV. To obtain the normal picture color, press
POWER on the TV to switch off the TV for five minutes and
then switch it on again.
• Design and specifications are subject to change without notice.
