Adjusting Method
4) Attach a sensor of White Balance Meter (CA-100) to 80% of white level on the screen.
5) Adjust White Balance by varying Gain of R, G, B
• Gain of R, G, B should be adjusted to DP ±10, if out of these range then classify as a fault.
• Set Color Coordinate to
x=0.275 ±0.005, y=0.285 ±0.005 (Low : 0.295)
and the Color
Temperature should be over 10,000-degree K (standard R&D center equipment).
6) Attach a sensor of White Balance Meter to 40% of white level on the screen.
7) Adjust White Balance by varying the BIAS values of R, G, B
• BIAS Values of R,G,B should be adjusted to DP ±10 ,if out of these range then classify
as a fault.
• Set the Color Coordinate to
x=0.275 ±0.003, y=0.295 ±0.003
(standard R&D center equipment).
• Does not need to adjust if the deviation of color coordinate is within ±0.003.
8) Repeat No 4) to No 7) until getting the Color Coordinate is
x=0.275 ±0.003,
y=0.295 ±0.003 at 40%
and
x=0.275 ±0.005, y=0.285 ±0.005 at 80%
white level.
Then adjust Sub Contrast to
over 140 Cd/m
2
after attaching a sensor of White Balance
Meter to 100% of white level on the screen.
9) To exit from Service mode, press Menu button on the remote control.
