Possible Remedies
If the item you want to choose appears in gray, you cannot select it.
Turn the projection TV's power off and on again.
Use Auto Program in the Channel menu to add receivable channels that are not
presently in TV memory (see page 52).
Check your cable settings.
Make sure Cable is set to ON in the Channel menu (see page 51).
Increase the volume of the cable box using the cable box's remote control. Then
press TV (FUNCTION) and adjust the projection TV's volume.
Make sure Cable is set to ON in the Channel menu (see "Cable" on page 51).
Use Auto Program in the Channel menu to add receivable TV channels that are
not presently in TV memory (see page 52).
Use Auto Program in the Channel menu to add receivable TV channels that are
not presently in TV memory (see page 52).
Be sure you have not inadvertently switched your projection TV from channel 3 or
4 setting if you are using another device to change channels.
If you are using another device to control channels, be sure the "function" button
for that device has been pressed, or the slide switch is set correctly. For example, if
you are using your cable to control channels, be sure to press SAT/CABLE.
Be sure the Video Label feature has not been set to Skip (see page 56).
You have selected a text option in the Setup menu and no text is available (see
page 55 to reset Setup selections). To turn this feature off, select OFF in the
Caption Vision option. If you were trying to get closed captioning, select CC1
instead of Text 1-4.
Be sure your twin picture is set to a video source/channel that has a program airing.
You may be tuned to a video input with nothing connected to it. Try cycling
through your video inputs using TV/VIDEO.
Twin View is not set to receive a signal from the AUX input. If you have
connected a VCR, DVD player or satellite receiver to the AUX input on the
projection TV, it will not show in the second picture.
Both may be set to the same channel. Try changing channels in either the main
picture or the window picture.
You may be running all your channels through a cable box. The cable box will
only unscramble one signal at a time, so you cannot use the Twin View feature. If
possible, run a direct cable to your projection TV's VHF/UHF input (this will only
work if your cable system provides an unscrambled signal).
Be sure the video label has not been set to skip your video inputs. See the Setup
menu on page 55.
Verify that Favorite Channel is set to Manual in the Channel menu (see
"Favorite Channel" on page 51).
