MAINTENANCE / WARNING / TROUBLESHOOTING GUIDE
•IGNITION NOISE:
Black spots or horizontal streaks may appear, picture may flutter or drift.
Usually caused by interference from automobile ignition systems, neon
lamps, electrical drills and other electrical appliances.
•GHOSTS:
Ghosts are caused by the television signal following two paths. One is the
direct path and the other is reflected from tall buildings, hills or some
other objects. Changing the direction or position of the antenna may
improve reception. Ghosting may also be caused by defects in the
antenna system such as unshielded leads or connecting several sets to
the same antenna without using multiple antenna couplers.
Ghosting occurring when the plasma display is connected to a cable TV
system may indicate a bad cable wire or loose connection. Confirm that
the cable wire is properly connected.
•SNOW:
If your receiver is located in the fringe area of a television station where
the signal is weak, your picture may be marred by the appearance of
small dots. When the signal is extremely weak, it may be necessary to
install a special antenna to improve the picture.
Snowing occurring when the plasma display is connected to a cable TV
system may indicate a bad cable wire or loose connection. Confirm that
the cable wire is properly connected.
•The plasma display panel is lighting the phosphors by the discharge of
internal radiation. Depending on the screen contents, in rare cases this
may cause vertical stripes to appear because of failure to light. Please
note that this is not a malfunction.
Ver tical stripes appear,
depending on the screen
contents.
•RADIO FREQUENCY INTERFERENCE:
The interference produces moving ripples or diagonal streaks, and in
some cases, causes loss of contrast in the picture.
