Voltage margin adjustment is required after the Panel Assy is replaced with one for service.
• Basically, the Panel Factory menu is used for the voltage margin adjustment.
• The 60-Hz video sequence is used as the drive sequence.
• While adjusting the voltage margin using the Panel Factory menu, the current drive sequence is indicated on the screen, as
shown below. Make sure that 60VS is always indicated during adjustment.

[Preparations]
• When the Raster Mask for margin adjustment is displayed during Panel Factory mode, the Panel White Balance setting
value is default, and the Panel Gamma setting is "Straight" in the PANEL-1 ADJ layer. The third line of the OSD during
Panel Factory mode is "----/
∗∗∗∗
," where "
∗∗∗∗
" is the type of drive sequence set.
• If you wish to adjust using RS-232C commands, note that the commands are different from those used during Factory mode.
The commands for this are indicated below:
PAV S00: To switch from Panel Drive mode to Panel Factory mode
VFQ S03: To switch the Drive Sequence to Video 60 H
WBI S01: To temporarily reset the Panel WB adjustment value to default (To cancel resetting, issue WBI then S00.)
PGM S00: To switch the Gamma setting to "Factory"
Note: If the power is shut down during the adjustment procedure, issue the above commands again.
