and BIAS Gamma values are correct, and then press the ”ok” key in remote control. For each color temperature setting,
please repeat the procedure (1)-(3). Only x and y value will change in different color temperature mode (in 8680K, x=288,
y=301; in 10180K, x=270, y=292) and Y values are all the same in each color temperature mode (dark level Y=1.0, bright
level Y=40).
4 .1 Color Temperature setting in YPBPR Mode
1. Turn on Color Analyzer CA-100 and reset CA-100.
2. Switch PDP input signal source to YPBPR mode.
3. Set up Video Pattern Generator (Astro, Model= VG-828H).
Timing set = 640 x 480 @ 60Hz;
Video = Analog (the YPBPR output mode)
Connect PDP YPBPR input connector with Astro to receive YPBPR signal.

4.2 Adjusting procedure:
1. Receive Astro VG-828H YPBPR dark level center block signal (14 IRE), follow the ”Factory Setting Procedure” to go into
factory setting mode and you will see the 7180K color temperature setting OSD menu.
2. 7180K dark level center block adjustment procedure:
A. Press (Zoom -) or (Zoom+) key in remote control to select G-BIAS, and adjust Y=1.1 FL±0.1FL
B. Press (Zoom -) or (Zoom+) key in remote control to select R-BIAS, and adjust x=308±15FL
C. Press (Zoom -) or (Zoom+) key in remote control to select B-BIAS, and adjust y=298±15FL
