After the panel is replaced with one for service, voltage margin adjustment is required.
Basically, voltage margin adjustment is performed using the Panel Factory menu.
After the panel is replaced and the unit is turned on, clear the pulse meter first.
For details on how to clear the pulse meter, see "8.3 HOW TO CLEAR HISTORY DATA".
∗
1: As various corrections are made referring to the pulse-meter count to calculate how long the panel has been used, if
adjustment of the panel for service is performed without clearing the pulse-meter count, proper adjustments will not be
performed.
∗
2: The drive sequence for Video 60-Hz is used for adjustment. When adjustment is made using the Panel Factory menu, the
current drive sequence is displayed on the screen, as shown in the figure below. Make sure that 60VS is always indicated
during adjustment.

[Preparation]
In the "PANEL-1ADJ" layer, the Panel White Balance value is reset to default, Panel Gamma is set to Straight, Noise is set to
OFF, LUT mode is set to ON and Reset active control is set to OFF.
If adjustment is performed using RS232C commands, unlike the case of Factory menu operation, adjustments are not
interlocked. Therefore, settings must be performed individually, by issuing commands. (See the section on preparations before
adjustment.)
