This AV color balance adjustment should be performed

before white Balance Adjustment.

V

It is very import to use adjustment pattern like Fig.7.

1) Within the pattern, color sequence should be aligned

: W-Y-C-G-M-R-BLUE-BLACK.
(If color sequence is reversed (Black -> ... -> White),
reverse the pattern with REV key, when using Master
pattern generator like MSPG-925)

2) If minimum Black level and/or maximum White level is

not correct, select 100% color bar pattern.

1) Remote controller for adjustment.
2) AV Pattern Generator.

: 802F Pattern Generator, Master(MSPG-925FA), etc.
(Which has PAL Composite Video format output with
standard(1.0 Vpp) Vertical 100% Color Bar Pattern as Fig7)

1) Input the PAL Composite Video into video input.

(Input 50Hz : AV3/AV4 Input)

2) Set the PSM to Standard mode in Picture menu.
3) Press IN-STAR key on R/C for adjustment.
4) Press the 

G

(Vol. +) key operate to set, then it becomes

automatically.

5) Auto-RGB OK means completed adjustment.

1) Remote controller for adjustment.
2) Color Analyzer.(CA-100 or same product)
3) Auto W/B adjustment instrument.(only for Auto adjustment)
4) AV Pattern Generator.

For  manual  adjustment,  it  is  also  possible  by  the  following

sequence.

1) Select white pattern of heat-run mode by pressing power on

key on remote control for adjustment then operate heat run
more than 15 minutes.

2)  As  below  Fig.9,  Supply  216Level  (85  IRE)  full  screen

pattern to Video input.
