Description
PDP POWER
VOLTAGE
[35V]
CAUTION:
•
During adjustment operation of PDP POWER VOLTAGE,
don't touch the heat sink of the MAIN POWER UNIT. If
you touch it, electric shock may be caused.
< When MAIN POWER UNIT is not replaced >
(1) Connect the DC voltmeter to the CN0C4 connector
and turn on the power. (See Fig.5)
(2) Adjust Vs (190V ADJ) VR and Va (60V ADJ) VR so that
the Vs and Va voltage coincides with the values in the
voltage label.
(3) Input a PAL all-black signal and check that it coincides
with the values in the voltage label.
(4) Readjust if the adjusted value is different from those
in the voltage label.
NOTE:
•
Designed value for the panel is printed on a label on the
upper-left at the back of the PDP. (See Fig.6)
< When MAIN POWER UNIT is replaced >
CAUTION:
•
Before making adjustments, be sure not to turn on the
power when the CN8003 and CN8005 connectors are
connected, as this may cause the PDP to break down.
(1) Disconnect the CN8003 and CN8005 connectors on
the MAIN POWER UNIT.
(2) Connect DC voltmeter to the CN0C4 connector and
turn on the power. (See Fig.5)
(3) Adjust Vs (190V ADJ) VR and Va (70V ADJ) VR so that
the Vs and Va voltage coincides with the values in the
voltage label.
(4) Turn off the power, and connect the CN8003 and
CN8005 connectors and turn on the power again.
(5) Input a PAL all-black signal and check that it coincides
with the values in the voltage label.
(6) If the adjusted value is different from those in the
voltage label, fine-tune without unplugging the
connectors.
CAUTION:
•
Designated power supply voltage of the panel (Vs, Va)
varies according to the PDP unit.
•
Pay careful attention during adjustment, as any error in
procedure may cause the PDP to break down.
