Static Convergence
1. Preset the front panel BACKGROUND control to mechanical center.
2. Preset the front panel BRIGHTNESS control to maximum.
3. Temporarily disconnect the power from the instrument and remove the PC board shield cover from
the rear of the CRT Display Module by prying evenly on all four sides.
4. Reapply the power and from the Display Test menu select the white cross-hatch test pattern.
5. Check the four dots located around the center intersection of the cross-hatch pattern for coincidence
of blue, red, and green dots. If the dots are not coincident, adjust H.STAT (RV703), located on the
rear PC board, to obtain horizontal coincidence and V.STAT (RV803), located on the bottom PC
board, to obtain vertical coincidence. See figure 4-18.
Note
Due to interaction, the BEAM LANDING will need to be readjusted if either
H.STAT or V.STAT adjustments are made. Once the BEAM LANDING is
readjusted, repeat step 5, if necessary, to obtain center-screen coincidence of
the dots.
