3-8. GREEN AND BLUE REGISTRATION
ADJUSTMENTS
1. Input cross hatch signal.
2. Enter service mode. Select OFF of SERVICE
MODE to cut off red output.
3. Turn the vertical blue (V.B) and horizontal blue
(H.B) variable resistors to adjust blue
picture convergence in relation to green picture
according to the following steps :
(Adjustment procedure)
1. [LIN (linearity)
[SIZE (amplitude)]
[CENT (center position)
2. [BOW] [SKEW] [CENT (center position)
3. [PIN (pin warp)
[SUB BOW] [BOW]
[H/M. PIN (horizontal middle pin warp)
4 . [KEYS (trapezoid) [SUB SKEW] [SKEW]
5. [M.WAVE (middle sine wave warp)
[WAVE-A (upper and lower sine wave warp)
[WAVE-U (upper sine wave warp)
