2-4. FOCUS ADJUSTMENT
Confi rm neck assembly Z axis position. (See Figure 1)
1. Input a dot signal.
2. Set Video Mode to STANDARD.
3. Adjust focus VR counter clockwise (Over-Focus) to confi rm the dot’s
shape. Center should be very slightly oval with left and right sides
balanced.
4. Input a HD monoscope signal.
5. Confi rm center focus with focus VR.

2-4.1. DYNAMIC FOCUS/DYNAMIC QUADRA-
POLE DATA
Normally, no adjustments are necessary for these systems. If for some
reason the data is lost, use the data from Table 1 below:
1. Write the data from any non-vertically compressed mode, then
use the CPY1 function (CXA2170D-4 Item 6) to copy the data to the
vertical compressed modes.
Note:
V-compressed data is identical to non-v-compressed
data. Service personnel with a trained eye can adjust the DF or
DQP registers to adjust DF phase (Item 7) or DQP phase (Item 8),
respectively, to balance left and right focus. Refrain from adjusting
more than 5 steps from table data below. Further adjustment indicates
a circuit problem -- troubleshoot to cause.
CAUTION:
Be sure that Neck Assembly is in the proper location.
Mark position before moving or replacing neck assembly.
(See Section 2-4 Figure 1 - before changing DF/DQP data or
troubleshooting circuit when DF/DQP is suspect.)
Procedure to adjust or check:
1. Short Q8018 B-Gnd to disable DF. B Mark is on the circuit board.
Circuit connection changes should always be done with the power off.
CAUTION: Q8018 heatsink is live and peak voltage is 250V.
2. Input a cross hatch signal.
