3.6.5
Repeat procedures 3.6.2 through 3.6.4 for the other screen modes.
(Completion of the red adjustment)
3.7 Coarse Adjustment and Fine Adjust-
ment of the Blue
Make coarse and fine-adjustments of the blue in the same manner
as with the red, described in 3.5 and 3.6.
3.8 Confirmation of Adjustment
After the green, red, and blue adjustments are finished, check
convergence errors with the patterns for all three colors on the
monitor.
Check the patterns in all SCREEN modes, and if any error in
convergence is recognized, readjust convergence in MANUAL
CONVER. mode.
Note:
Be sure NOT to change the green pattern during
readjustment.
IMPORTANT!
(1) When all the adjustments are completed, or when adjustment
should be temporarily interrupted, adjustment data must be
written to the EEPROM, in the following manner:
When all the adjustments are completed, or to interrupt adjust-
ment, press the MENU key to quit Convergence Adjustment
mode. The display will be unstable for several seconds, but
this is because the data are being written to the EEPROM.
Wait without doing anything until the display becomes stable,
which means writing of data to the EEPROM is finished.
If the power of the TV is turned off (standby) during
Convergence Adjustment mode (coarse and fine-adjustments),
turn on the TV, enter FACTORY mode, and enter
Convergence Adjustment mode by pressing the SET/ENTER
key. Then press the MENU key. The data will be written to
the EEPROM as described above.
(2) Do NOT turn off the main power during or after convergence
adjustment.
If you do so, the adjusted data may be lost. If the data are
lost, you must make all the adjustments again.
(3) When the CENTER POINT (test cross) or MULTI-POINT
(user convergence) adjustments have been made by a user,
and if the unit enters FACTORY Convergence Adjustment
mode (with the INPUT4 and SET/ENTER keys), the user's
adjustment data will be all cleared and returned to the factory-
preset values.
Be sure NOT to enter this Convergence Adjustment mode
except when a repair related to convergence or a repair that
requires convergence adjustment later, is needed.
If you inadvertently enter Convergence Adjustment mode,
readjust the convergence.
