13-3. 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,
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 401, voltage of D.M.M adjustment
as same as Vs voltage which on label of panel right/top
( deviation ; ±0.5V)
( deviation ; ±0.5V)
