2.6.2 Press key “6” to enter sub-brightness adjustment.
2.6.3 At standard state, adjust “BRTC” , until the secondary grey just be seen.
* Do not change value “BRTS”.
2.7 Picture geometric adjustment
2.7.1 Vertical geometric adjustment
a. Input a PAL cross hatch pattern signal .
b. Press key “2” to enter Vertical geometric adjustment .
c. Use remote control to adjust one by one , watch the figure, until the center or the
corner grid has a same size .
d. When adjust vertical position , make the center of vertical intermediately.
e. In “5VSL”, the second half may blanking , adjust the first half at display range.
Remark :
：
1 5VSC , 31 is fixed, don’t adjust .
2 5VPOS for vertical position.
3 5VAM for vertical amplitude.
4 5VSL for vertical slope.
5 5VL for vertical linearity.
6 5SCL for vertical S-correction.
7 5WBR for end of blanking time on 4:3 mode (16:9 tube).
8 5WBF for start of blanking time on 4:3 mode (16:9 tube) .
9 5BSWBR for right side black width of blue screen .
10 5BSWBF for left side black width of blue screen.
* 5WBF/5WBR only use on matching 16:9 tube, at 4:3 picture mode, adjust
blanking time of R and F. First press “ZOOM” key switch to 4:3 mode, then adjust
5WBF and 5WBR respective to make the overscan meet the requirements.
*Adjustment is disabled when match 4:3 tube.
* 5BSWBR and 5BSWBF needn’t adjustment.
*Apply NTSC signal to adjust these registers for NTSC geometric
