Adjustment Instructions; Power Pcb Assy Voltage Adjustment; Adjustment White Balance - Zenith P60W26 Series Service Manual

ADJUSTMENT INSTRUCTIONS

These instructions are applied to all of the PDP monitor,
NP-00KB.
Because this is not a hot chassis, it is not necessary to
use an isolation transformer. However, the use of
isolation transformer will help protect test instruments.
Adjustment must be done in the correct order. If there
is no specific designation, the adjustment must be
o
performed at 25±5 C of temperature and 65±10% of
relative humidity.
The input voltage of the receiver must maintain
110~240V, 50/60Hz while adjusting. Operate the receiver
for about 15 minutes prior to the adjustment with 100%
white pattern (06CH). (Or white condition in HEAT-RUN
mode)
Enter into HEAT-RUN mode. Select the 2 W/B by pressing
ADJ button on Remote Control for adjustment. And press
the VOL + button. Press the VOL + button in HEAT-RUN.
(OSD display HEAT-RUN WHITE and screen display 100%
full WHITE PATTERN). Set is activated HEAT-RUN without
signal generator in this mode. Single color pattern of
HEAT-RUN mode uses to check the PANEL. (RED/BLUE/
GREEN)
Caution: If you turn on a still screen more than 20
minutes, an afterinage may occur in the black
level part of the screen.

POWER PCB ASSY VOLTAGE ADJUSTMENT

After replacing the PDP Module or Power Board, adjust
the Power PCB Assy voltage.

ADJUSTMENT METHOD
PFC ADJUSTMENT
After displaying the 100% white pattern (HEAT-RUN).
Connect TP PFC+ and TP PFC-(GND) to D.M.M. Turning
VR801, adjust to 380V(±1V).
VA ADJUSMENT
Connect pin 1 of P814 to (+) jack of D.M.M. After
turning the VR803(Va Adj), voltage of D.M.M
adjustment as same as Va voltage which on label of
panel Left/Top.(Deviation : ±0.5V).
VS ADJUSTMENT
Connect pin 9 of P803 to (+) jack of D.M.M. After
turning the VR804(Vs Adj), voltage of D.M.M adjust
as same as Vs voltage which indicated on label of panel
Left/Top (Deviation : ±0.5V).

WHITE BALANCE ADJUSTMENT
Operate the Zero-calibration of the CAÑ100, then place
the sensor to the PDP module surface when you adjust.
Manual adjustment is also possible by the following
sequence.
(1) Select the WHITE PATTERN of HEAT RUN mode by
pressing the ADJ button on Remote Control for
adjustment, then operate HEAT RUN more than 15
minutes.
(2) Supply 10 step gray scale bar signal in pattern
generater. (A/V Input)
