Black bands appear at the top and

❑
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 (page 33) to
optimize the picture while viewing these sources.
Remote control does not operate.
❑
Check the polarity of the batteries or replace the batteries.
❑

❑
If you are using another device to change channels, be sure you have not
inadvertently switched your TV from the channel 3 or 4 setting.
❑
If you are using another device to change channels, be sure to press FUNCTION
for that device. For example, if you are using your cable box to change channels,
be sure to press SAT/CABLE (FUNCTION) once, and the SAT/CABLE
indicator lights up.

There may be more than one code for the equipment that you are attempting to
operate.

There is a possibility that some non-Sony equipment cannot be operated by your
