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  100-240V~,
50/60Hz.
(5) The receiver must be operated for about 15 minutes prior
to the adjustment.
O
After  RGB  Full  white  HEAT-RUN  Mode,  the  receiver  must

on screen.
But it works abnormally, “No CA module” words display on
screen.
5. POWER PCB Assy Voltage
Adjustments 
(Va, Vs Voltage adjustments)
5-1. Test Equipment :
D.M.M. 1EA
5-2.Connection Diagram for Measuring
: refer to Fig.1
5-3. Adjustment Method
(1) Va Adjustment
1) After receiving 100% Full White Pattern, HEAT RUN.
2) Connect + terminal of D.M.M to Va pin of P812, connect
- terminal to GND pin of P812.
3)  After  turning  VR901,  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 + terminal of D.M.M to Vs pin of P812, connect
– terminal to GND pin of P812.
2)  After  turning  VR951,  voltage  of  D.M.M  adjustment  as
same  as  Va  voltage  which  on  label  of  panel  right/top.
(Deviation; ±0.5V)
If you turn on a still screen more than 20 minutes (Especially
Digital pattern, Cross Hatch Pattern), an afterimage may occur
in the black level part of the screen.
Each PCB assembly must be checked by check JIG set.
(Because power PCB Assembly damages to PDP Module,
especially be careful)
