2-9.2. 1080I HD MODE ADJUSTMENT
1. Input a 1080i cross-hatch signal and an HD monoscope full signal
that contains overscan markers. (From service mode, verify 1080I
mode).
2. If this procedure was not performed for full mode, adjust the raster
position per Section 2-8. H Raster Center Adjustment.
3. Adjust the geometry similar to Full DRC mode. Vertical size is 11.7
± 0.1 sq. and horizontal size is 15.6 ± 0.1 sq., if monoscope signal is
available. Otherwise, set the Vertical size to 91.0 ± 0.6% scan and
Horizontal size as 91.0 ± 0.6% scan.
4. Adjust HPOS as necessary.
Note:
if necessary, touch up the geometry using the data registers
listed above for full mode. Check NTSC full mode for adjustment side
effects because some data registers are shared between modes, in
which case a balance must be achieved.
5. Write the data into memory before changing modes.
2-9.3. VERTICAL COMPRESSED MODE
CHECK AND CONFIRMATION
(FOR 4X3 CRT ONLY)
1. Input a monoscope and crosshatch signal.
2. Set CXA2170-P4 item 26 IDSW to 4 (VC 960i).
3. Check for vertical compressed mode distortion.
4. Adjust VPIN as necessary to correct upper lower horizontal line
straightness. Adjust other registers as in Full mode above as
necessary, being careful to balance any shared data effect between
modes.
5. Repeat 3-4 for IDSW set to 3 (VC 1080i). Write the data before
changing modes.
6. Write the data before changing modes.
2-9.4 NORMAL,
ZOOM
AND
WIDE
ZOOM
MODES
1. Check Normal and Zoom modes for size and position.
2. Optimize VPIN adjustment in Normal mode for the straightest upper
and lower horizontal lines. For other registers, remember to check for
shared data side effect.
3. Write the data before changing modes.
4. Check Wide Zoom mode for size and position.
Wide Zoom is a specially adjusted mode to fi t a 4:3 picture into a
16:9 format, and is only available on wide screen models.
5. Set the following key registers to the data indicated:
VSCO = 10, UVLN = 4, LVLN = 4, SLIN = 10, MPIN = 9,
then adjust the other data registers shown here for Full mode to
straighten horizontal and vertical lines. The picture on the top and
bottom edge is deliberately compressed vertically, and similarly the
picture on the left and right side is expanded horizontally.
Note
: Do not adjust horizontal and vertical linearity to make another
Full mode. Most data registers for this mode are dedicated to Wide
Zoom mode only so there should be no adjustment side effects to
other modes but please confi rm this.
6. Write the data before changing modes.
