2-23 USING THE INTERNALLY
GENERATED PATTERNS
The TV can internally generate various patterns
in various formats (480i, 480p, 1080i, 720p).
These patterns can be used in place of those
which would otherwise require an HDTV RF
pattern generator. These internal patterns
cannot be used in place of the 480i, 480p,
and 1080i component (Y/Pb/Pr) pattern
signals called for in some of the previous
picture adjustment sections. For these, a DVD
player with progressive scan capability and a test
DVD disc having various patterns is
recommended.
To display the internal patterns follow this
procedure:
1. Tune the TV to any DTV channel.
There does not have to be a DTV
broadcast active at this time. Simply
use the remote control to direct-tune a
DTV channel, for example channel "2.1"
Be sure to use the decimal point or "dot"
button on the remote, and make sure
the number after the decimal point is "1"
or higher. Do not be concerned if the
words "Now Tuning" or "No Signal"
appear on the screen.
2. Turn the TV off, then enter the service
mode.
3. Select category "DTV".
4. Select adjustment item # 1 "PATN".
5. Select the pattern you want to display by
changing the data in "PATN" as follows:
"0" = 1080i black screen.
"1" = 1080i cross-hatch w/ size markers.

markers.
"22" = 480p 1/2 color bars, 1/2 gray
sweep.
"23" = 480p white window.

"28" = 480p frequency response.
"29" = 480p gray raster.
"30" = 480p diagonal lines.
"31" = 720p cross-hatch w/ size
markers.
"32" = 720p 1/2 color bars, 1/2 gray
sweep.
"33" = 720p white window.
"34" = 720p color bars.
"35" = 720p white raster.
