Possible Remedies
❏
You have selected a text option in the Setup menu and no text is available. (see
page 79 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 LCD 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 LCD 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 80.
❏
Ensure that Video Label is not set to "Skip" (see "Video Label" on page 80).
❏
Make sure the image is supported by the LCD projection TV (see page 58).
❏
Make sure the Memory Stick is inserted properly (see page 60).
❏
Memory Stick functions are not available while using Twin View, Freeze or
Favorite Channel functions.
❏
This indicates that the image does not support a thumbnail view. Selecting the icon,
however, displays the full-size image on the screen. It could also indicate that both
the thumbnail and full-size images are corrupted or not supported
❏
Be sure the LOCK switch on the Memory Stick is set to off.
❏
If a blank square appears instead of the thumbnail image, this indicates that the
image does not support a thumbnail view and cannot be rotated.
❏
There is no audio available while using Memory Stick.
❏
Dashes appear instead of the file name if the image was recorded using equipment
that is not DCF-compliant. Dashes also appear if a DCF-compliant file was
renamed.
