Set the BRILLIANCE control at max. position, and the DEEP BLUE background is clearly
distinguished from the blank area surrounding it. Set R64 (H-POSITION) so that the upper
and lower blank areas become equal in width.
Set R65 (BLUE) to the center position. Adjust R66 (RED) so that the reddish brown can be
identified under the BRILLIANCE setting of "4" to "6" position.
NOTE: Do not adjust the potentiometers on the CE VIDEO board connected to the CRT
neck.
