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 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
DRC Palette setting (see page 64) to
optimize the picture while viewing these sources.
"Iris Unit error" appears while
Advanced Iris is active
❏
The Iris Control may have a problem. Call your local Sony Service Center.
