2.14.3 Convergence
point adjustment
Adjustment preparation
(1) Select color to adjust.
"RECALC' - Green
"0" - Red
"INPUT" - Blue
(2) Use 4, 6, 2, and 5 to move the cursor position
(dotted lines).
(3) Use cursor buttons to move the convergence
point.
(4) Three adjustment modes are available:
1.
(3x3) Press "RECALL" 5 times
2.
(7x5) Press "0" 5 times
3.
(13x9) Press "INPUT" 5 times
NOTE:
3 x 3 mode can only be accessed at start
of adjustment
from clear data in ram adj.
mode.
For touch-up, only the (13x9) mode is necessary.
This will adjust every cross-hatch intersection point
on the screen.
For complete adjustment, start with (3x3) mode. This
will adjust center point and eight edge points only,
but will greatly reduce adjustment
time. Then use
(7x5) mode,
and finally
(13x9)
mode to finish
convergence.
If "S" distortion appears between cross-hatch lines
repeat (7x5) mode to change calculation process
while adjusting to remove distortion, then return to
(13x9) mode to finish touch-up convergence.
Adjustment procedure
(1) Start adjustment at the center of the screen.
(2) Continue adjustment at next closest position.
(3) Adjust center
area
first, ending
with edge
sections.
(4) When convergence
is acceptable, press MOVE
to write data to ROM memory. ROM WRITE? is
displayed to alarm system that ROM will be
overwritten
with new data. Press the MOVE
button again to write displayed data to ROM.
(5) DATA WRITE TO ROM will take approximately
20 seconds and no picture will be displayed.
(6) Green dots will be displayed when operation is
complete.
(7) Press MUTE to return to convergence
pattern,
then confirm again convergence is acceptable.
Notes:
(1) Display only green for easier adjustment
and match to jig screen. Press "MENU",
THEN PRESS "RECALL'.
(2) Write data to ROM after green adjustment.
Once green has been confirmed to match
jig screen, the jig screen can be removed.
Do not readjust the green color after jig
screen has been removed. This is now your
reference color.
(3) Display green and red only and match red to
green.
(4) Display all colors and match blue to green
and red. Touch-up red color if necessary.
(5) Existing DATA in ROM can be read by
pressing the SWAP button 2 times. This
data
can
be
used
after
replacing
a
component (CRT, DY, etc.) Where complete
convergence
adjustment
is not necessary
be careful not to overwrite this data.
DO NOT write cleared RAM data into ROM
or a complete convergence adjustment will
be necessary.
