8, 9, 10
Image appears doubled or
tripled.
• Is the antenna facing the right direction?
• Is the antenna receiving any signals reflected off mountains or buildings.
-
Spots appear in images,
images shake, or color patches
appear in the four corners.
• Is the TV being affected by geomagnetism or other interference
(automobiles and trains, high voltage power lines, neon, motors,
magnetic steel frames, steel windows, etc.)? Turn off the power for
approx. 20 min. and turn back on or change positioning of the TV set. If
this does not fix the problem, the TV needs magnetic shielding.
-
When the TV set is turned on
in a dark room, the outer edges
of the screen spark
momentarily.
• Due to the internal structure of the CRT set, some parts of the fluorescent
components spark, (created by high voltage) when the TV set is turned
on. This is not a malfunction.
-
Unclear or overly bright colors
on parts of the screen
• When white is displayed on a certain part of the screen for a while, the
white portion tends to tint with color. When the bright image disappears,
the screen will return to its normal color.
-
Left and right ends of the
screen, columns and frames
appear curved.
• Receiving broadcast or changes in brightness on the screen can cause
curves on the screen.

moment when changing
channels using the VCR.
• The image distorts when channels are changed.
During Panasonic AUTO
mode, the screen size
sometimes changes.
• Depending on the program content, even when the screen is supposed
to automatically zoom, if the beginning scene is dark, it may take a
while for it to zoom.
• During a 4:3 screen, if the top and bottom of the image is dark, it may
zoom.

• Has the screen position been changed?
If so, adjust screen positioning.

A clicking and buzzing sound
is made when the TV is turned
on.
• This is the sound of the Geomagnetic correction function creating a
