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.

Interlocked settings for Voltages Vyknofs1/3/4
For the 9th-generation PDPs, interlocked setting for
NG
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.
