Cross Hatch Adjust Select CROSS HATCH test pattern and check for display linearity. All
the following adjustments are made on the solder side of CRT controller
PCB.
1. Adjust HORIZONTAL LINEARITY with variable inductor L3 to
make each box symmetrical horizontally.
2. Adjust HORIZONTAL PHASE with variable resistor R63 to center
the cross hatch from right to left.
3. Adjust HORIZONTAL SIZE with variable resistor R95 to 0.25 ±0.1
inch from center of the outer cross hatch line to the bezel edge on
each side.
4. Horizontal linearity, phase, size, and pin cushion may need to be
readjusted because of their affect on each other.
5. Adjust VERTICAL LINEARITY with variable resistor R92 to make
each box in the cross hatch as square as possible.
6. Adjust HEIGHT with variable resistor R75 to 0.25 ±0.1 inch from
center of the outer cross hatch line to the bezel edge on the top and
bottom.
7. Adjust VERTICAL CENTERING with variable resistor R47 to center
the cross hatch vertically.
8. Vertical linearity, height, and vertical centering may need to be
readjusted because of their affect on each other.
9. Push the Trim Knob to exit.
Intensity Adjust Select the VERTICAL GRAY BARS on the monitor display and push the
Trim Knob.
1. Adjust display INTENSITY with variable resistor R1on the CRT
control PCB. Adjust R1 until the retrace lines just disappear.
2. Adjust CONTRAST variable resistor R32 to make all gray scales are
visible. The brightest bar should not be blurry.
3. Push the Trim Knob to exit.
Completion Select RESTART SYSTEM to return to the MAIN MENU.
Assemble unit and return to service.
