Preparation before adjustment
[Replacement with the panel for service is completed.]
[To the main flowchart (1)]
Turn the unit on. / [PON]
Enter Factory mode. / [FAY]
Set PM/B1-B5 to CLEAR (to clear the pulse meter). / [CPM]
Set HR-MTR to CLEAR (to clear the hour meter). / [CHM]
Turn the unit off. / [POF]
Turn the unit on. / [PON]
Enter Factory mode. / [FAY]
Display RST MASK 01 (white). / [MKSS51]
Select Video 60-Hz sequence. / [VFQS03]
∗ To store the [VFQS03] command in memory, transmit it
after displaying the mask.
Note:
On the XGA model, the circuits are not mounted in VX1.
Note: If you perform the adjustment by RS-232C commands, the following commands must be added
before going to the main flowchart (1):
[PAV S00]: To set panel drive mode to Factory
[WBI S01]: To temporarily reset the Panel WB adjustment value to default (WBI S00 cancels this setting.)
[PGR S00]: To set the gamma R value to that for Factory mode
[PGG S00]: To set the gamma G value to that for Factory mode
[PGB S00]: To set the gamma B value to that for Factory mode
[DIZ S03]:Dither ON,L dither ON, noise OFF
Procedures for resetting corrections for change over time
Perform aging for 5 minutes.
Enter the initial values for the panel for service.
