1. Adjust RGB AMP VR36 so that the voltage between SYNC signals is
4.0V+0.1Vp-p.
2. Adjust-VR32, VR33 and VR34 so that the GAMMA 0, GAMMA 2 and
CONTRAST voltages are 3.5V+0.05V.
3. Adjust BLACK ADJ VR35 so that the voltage at the 4th step from the
pedestal is 3.0V+0.05V.

Adjust GAMMA
0 VR32 so that the voltage at the 3rd step from the
pedestal is 1.0V+0.05V.
. Adjust BLACK ADJ VR35 so that the voltage at the 4th step from the
pedestal is 2.0V+0.05V.
(Note) There are 2 points where the voltage can be adjusted to 2V, but
always rotate the potentiometer clockwise in this adjustment.
If the potentiometer is rotated counterclockwise, the adjustment in 6
below will not be achievable.
