Troubleshooting
No reception of digital
signals.
Make sure the auto channel scan has
been completed.
The auto channel scan must be
completed when you set up your TV
for the first time or move it to a
location where previously
unavailable channels are broadcast.
The selected channel may not be
broadcasting.
When the auto channel scan is
interrupted and not completed, some
channels will not be received. Make
sure the auto channel scan has been
completed.
The entered channel
number changes
automatically.
Many digital channels have alternate
channel numbers. Your TV changes
the numbers automatically to the
ones signifying the broadcasting
station. These are the numbers used
for analog broadcasts.
Problem Solution
Remote control does not
work.
If you are using an outside antenna,
check the condition of the wiring and
connections.
Check the remote control batteries.
Make sure that there is no obstacle
between the remote control sensor
on your TV and the remote control.
Test the signal output. If the signal is
good, then there may be infrared
sensor trouble.
When there is an infrared-equipped
device such as a computer is near
your TV, the device may interrupt the
remote control signal. Move the
infrared-equipped device away from
your TV, change the angle of the
infrared sensor, or turn off the
infrared communication function.
Aim the remote control directly at the
remote control sensor on the front of
your TV.
Reduce the distance between the
remote control and your TV.
Make sure that the batteries are
inserted correctly. The + and –
symbols on the batteries must match
the + and – symbols inside the
battery compartment.
Misspelled captions are
displayed.
Closed captioning production
companies may broadcast programs
without correcting the misspelling in
a live broadcast.
Captions are not entirely
displayed, or captions
appear after the dialog.
Captions that are delayed a few
seconds behind the actual dialog are
common for live broadcasts. Most
captioning production companies
can display dialog at a maximum of
220 words per minute. If a dialog
exceeds that rate, selective editing is
used to ensure that the captions
remain up to date with the current
dialog.
Captions are displayed as a
white box or no caption is
displayed in a closed
caption-supported
program.
Interference from buildings or
weather conditions may cause
captioning to be incomplete.
Broadcasting stations may shorten
the programs to insert commercials.
The closed caption decoder cannot
read the information of shortened
programs.
No caption is displayed
when playing the
videotape containing
captions.
The videotape may be illegally
copied, or the caption signal might
not have been read during copying.
Black box is displayed in the
TV screen.
The text mode is selected for caption.
Select CC1, CC2, CC3, CC4, or Off.
