❏
Check the antenna/cable connections.
It is strongly recommended to connect the antenna using a 75-ohm coaxial cable
to get optimum picture quality. A 300-ohm twin lead cable can be easily affected
by radio noise and the like, resulting in signal deterioration. If you use a 300-ohm
twin lead cable, keep it away as far as possible from the LCD projection TV.
Do not use an indoor antenna because it is especially susceptible to radio noise
(see page 25).

Double images
❏
Use a highly directional outdoor antenna or a cable (when the problem is caused
by reflections from nearby mountains or tall buildings).
❏

Auto
. If doubled
images appear with Auto , select the best value from 1 to 4 (see page 85).

Black bands appear at the top
and bottom of the screen
❏
Some wide-screen programs are filmed in aspect ratios that are greater than 16:9
(this is especially common with theatrical releases). Your LCD projection TV will
show these programs with black bands at the top and bottom of the screen. For
more details, check the documentation that came with your DVD (or contact your
program provider).
Certain programs on DVD or
other digital sources display a
loss of detail, especially during
fast-motion or dark scenes
❏
The compression used by certain digital broadcasts and DVDs may cause your
TV’s screen to display less detail than usual, or cause artifacts (small blocks or
dots, pixelations) to appear on your screen. This is due to your TV’s large screen
and ability to show very fine detail, and is normal for certain digitally recorded
programs. Adjust the reality/clarity in the
Palette
menu (see page 71) to optimize
the picture while viewing these sources.
Some video sources do not
appear when you press
TV/
VIDEO
❏
Ensure that Video Label is not set to “ Skip ” (see “ Video Label ” on page
