THOMSON 42WM02L, Service Manual

- 9 -

1. Application Object

These instructions are applied to all of the PDP monitor, NF-
01DC.

2. Notes

(1) 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 instrument.

(2) Adjustment must be done in the correct order.
(3) The adjustment must be performed in the circumstance of

25±5°C of temperature and 65±10% of relative humidity if
there is no specific designation.

(4) The input voltage of the receiver must keep 220/230V,

50/60Hz in adjusting.

(5) The receiver must be operated for about 15 minutes prior

to the adjustment. 

1) After receiving 100% white pattern, the receiver must be

operate prior to adjustment.(Or white condition in HEAT-
RUN mode)

2) Enter into HEAT-RUN mode 

- Select the HEAT-RUN by pressing ADJ button on

Remote Control for adjustment.

- Press the VOL + button in HEAT-RUN OFF.
(OSD display HEAT-RUN WHITE and screen display
100% full WHITE PATTERN) 

3) Set is activated HEAT-RUN without SET TOP BOX or

signal generator in this mode.

[

Single color pattern of HEAT-RUN mode uses to check

PANEL.(RED/BLUE/GREEN)

[Caution] If you turn on a still screen more than 20 minutes, a

afterimage may be occur in the black level part of the
screen.

3. POWER PCB Assy Voltage Adjustment

[

Replace PDP Module or Power Board, adjust certainly Power

PCB Assy Voltage.

Refer to Fig 1.

3-3. Adjustment Method

(1) Va Adjusment(Address Voltage Adjusment)

1) Connect pin 1 of CN806 or CN811 to (+) jack of D.M.M.
2) After turning the VR351(Va Adj), voltage of D.M.M

adjustment as same as Va voltage which on label of
panel right/top.(Deviation : ±0.5V)

(2) Vs Adjustment

1) Connect pin 1 of CN803 to (+) jack of D.M.M.
2) After turning the VR551(Vs Adj), voltage of D.M.M adjust

as same as Vs voltage which indicated on label of panel
right/top.(Deviation : ±0.5V)

(3) V-y Adjustment

1) Connect pin 1 of CN802  to (+) jack of D.M.M.
2) After turning the VR751(V-y Adj), voltage of D.M.M

adjust as same as Vs voltage which indicated on label
of panel right/top.(Deviation : ±0.5V)

(4) Vsetup Adjustment

1) Connect pin 5 of CN802 to (+) jack of D.M.M.
2) After turning the VR651(Vsetup Adj),voltage of D.M.M

adjust as same as Vs voltage which indicated on label
of panel right/top.(Deviation : ±0.5V)

(5) 5V Adjustment

1) Connect pin 3 of CN809  to (+) jack of D.M.M.
2) Adjust the voltage data of D.M.M to 5.1V by

turning.(Deviation : ±0.05V)

(6) STBY-5V Adjustment

1) Connect pin 3 of CN808  to (+) jack of D.M.M.
2) Check the voltage(5V) of D.M.M.
3) Adjust the voltage data of D.M.M so that voltage data of

D.M.M is 5V.(Deviation : ±0.05V)
