3- REGISTRATION AND
GEOMETRY ADJUSTMENTS
CAUTION:
In previous models that had
multiple display modes, e.g. ZOOM,
FULL, etc., it was mandatory that the
FLASH FOCUS button was pressed
before you exited a particular display
mode after you adjusted it in the service
mode.
HOWEVER,
in this model you
must wait until all display modes
have been adjusted before pressing
the FLASH FOCUS button!
3-1 SETUP FOR ADJUSTMENT
1. At the 4 insides of the screen, locate the
middle. Use a tape measure to identify
the middle.
3-2 MAIN DEFLECTION ADJ.
1. Place lens caps on the red and blue
lenses so that only the green color is
displayed. If lens caps are not
available, use the following method to
turn off the CRTs individually without
using lens caps:
Change the data in adjustment category
"2150P-2" , item # 1"RGBS" from "7" to
"2".
2. Display the internal test pattern # 11,
"480i cross-hatch w/ size markers" (see
section 2-23).
*
The "ALL COPY" feature copies the adjustment data
from the FULL mode to ZOOM, WIDE ZOOM, and HD
1080i FULL modes at the same time. This feature is
useful when major geometry/registration adjustments
are required. After "ALL COPY" is performed, go to
each mode and touch up as required. If major
adjustments are not required, do not perform "ALL
COPY". Instead, just touch up each mode as required.
See the section "Copy All Registration Data to
Other Modes" in section 3-3-5.4 for details on using
the "ALL COPY" feature.
The ALL COPY feature
must only be used once (after the NTSC FULL mode
has been adjusted).
