For the 9th-generation PDPs, interlocked setting for
Voltages Vyknofs1/3/4 is available on the Factory menu or
with RS232C commands, for easier adjustment. Therefore,
in the adjustment flowchart, the interlocked setting function
is used. (Individual setting for each adjustment value is
also possible, as in the conventional setting methods.
Note:
• The initial value for the interlocked setting value is 128,
including for factory preset values.
• See "[3] DRIVE ASSY" of "5.2 DIAGNOSIS FLOWCHART
OF FAILURE ANALYSIS" for calculation of actually used
voltage values.

Range of margin measuring
Read the voltage within the hysteresis (stricter value).
Definition of limits for the voltage margins
(abnormal lit/dead cells)
Interlocked settings for Voltages Vyknofs1/3/4
Abnormal lit cells:
• Five or fewer abnormal cells on the whole screen
• Two or fewer abnormal cells within a radius of 1 cm
Abnormal dead cells
• Fifteen or fewer abnormal cells on the whole screen
• Two or fewer abnormal cells within a radius of 1 cm
∗
: Abnormal cells visually recognizable at a distance of
1 meter from the panel must be counted.
∗
: Cells displayed abnormally for less than one second
are not counted as abnormal cells.
