* Refer to the below case to know what value is fixed.
* CASE
- First adjust the coordinate much away from the target
value(x, y).
1) x, y > target
(1) Decrease the R, G.
2) x, y < target
(1) First decrease the B gain.
(2) Decrease the one of the others.
- In case of decreasing the x, decreasing the R : fix G
- In case of decreasing the y , decreasing the G : fix R
3) x > target , y < target
(1) First decrease B, so make y a little more than the
target.
(2) Adjust x value by decreasing the R.
4) x < target , y > target
(1) First decrease B, so make x a little more than the
target.
(2) Adjust x value by decreasing the G.
(7) When adjustment is completed, Exit adjustment mode
using EXIT key on R/C.

13-4. 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 VR851, voltage of D.M.M adjustment as
same as Vs voltage which on label of panel right/top.
