CONVERGENCE ADJUSTMENT (manual color matching)
To avoid circuitry malfunctioning due to electrical load increase, never
utilize CONVERGENCE ADJUSTMENT (Line Convergence Adjustment in
particular) for adjusting screen size changes.
There is no means to restore the Convergence Adjustment data once
stored, to its original state. To avoid changing the screen size by errone-
ously using convergence adjustment, do not perform the green Line
Convergence Adjustment.
As such, be sure to perform the adjustment work from this page onward
by the Technical staff and the location’s maintenance Personnel who are
well versed in such adjustment work. In the Static Convergence
Adjsutments, if satisfactory adjustments can not be performed, do not
make another convergence adjustment inadvetently. Contact the office
herein stated or where the product was purchased from.
To avoid making the adjustment work ineffective, do not press the RE-
SET button during adjustment.
To discontinue adjustment work, keep pressing the TEST button for
approximately 3 seconds at the stage before storing the adjustment
data by pressing the WRITING button.
Should the screen be abnormally disturbed by noise due to static elec-
tricity, etc., turn the power off without storing the adjustment data.
Pressing the “up or down” PIC-ADJ but-
ton in the Convergence Adjustment
Mode status will display the Adjustment
Menu as this is the one applied at the
factory.
Adjusting this menu causes the
Customer’s adjsutment range to be
deviated.
Should the menu shown right be dis-
played by mistake, first choose EXIT by
using either “up or down” PIC-ADJ but-
ton and then press the SET button.
