10. Default Value in Adjustment
10-1. White Balance
(Default values maybe modified the module condition)
10-2. Press CH write condition
(1) AC on tilme on only one after assembled automatically
(2) CH recover SVC OSD manually
11. Internal press test
12. Sound spec.
Caution: Each PCB assembly must be checked by check JIG set.
(Because power PCB Assembly damages to PDP
Module, especially be careful)

Adjustment
(Va, Vs voltage Adjustment)
13-1. Test Equipment:
D.M.M 1EA
13-2. Connection Diagram for Measuring
Refer to Fig. 5
13-3. Adjustment Method
(1) Va Adjustment
1) After receiving 100% Full White Pattern, HEAT RUN.
2) C 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) C terminal of D. M..M. to Vs pin of P812,
connect -terminal to GND pin of P812.
2) After turning VR951 401, voltage of D.M.M adjustment
as same as Vs voltage which on label of panel right/top
( deviation ; ±0.5V)
