After loading we may need to adjust the set again according to alignment procedure
Alignment procedure
AGC adjusting
1) Power on the set and connect a TV signal to the tuner.

Intensity: 65 db
2) Press “i” key of remote control, th en press 6, 4, 0, 5 to enter factory menu, set AGC value to 14, and
check the noise of screen is just at minimum.
Alignment of white balance
1) Adjustment of white balance in VGA mode.
1.1 Connect VGA signal, 1024x768 60hz, and white field, to LCD TV set.
1.2 Set the values of brightness to 50%, and contrast to 70%.
1.3 Using a color analyzer to test the color coordinates.
1.4 Press 0,6,4,0,5 key in RC to enter factory mode, adjust the value of R, G and B to get x=284 15 and y=299 15.
1.5 Press exit key to exit.

Alignment of mid-brightness
1) Power on the set and connect a TV signal, 8 degrees gray signal, to the tuner.
2) Set the value of brightness to 50%, contrast to 70%. (Actually, it is the condition after reset)
3) Press “i” key of remote control, then press 6, 4, 0, 5 to enter factory menu. Then change the value of mid.brightness to make the 2 darkest bars can be identified, and the 2 brightest bars can be identified too. It means we get a perfect picture on the screen.
Note 1, we are finding a more perfect method to adjust white balance and sub-brightness. If we just adjust mid.brightness to get proper sub- brightness. The value of mid.brightness may be very low or
very high. With too low or too high value of mid-brightness, we may get a poor control curve of brightness.
