ADJUSTMENTS
•
Landing Rough Adjustment
1. Enter the full white signal. (or the full black dots signal).
2. Adjust the contrast to the maximum.
3. Make the screen monogreen.
Note: Off the outputs from R ch and B ch of SG.
4. Reverse the DY, and adjust coarsely the purity magnet so
2. Adjust the contrast to the maximum.
3. Make the screen monogreen.
Note: Off the outputs from R ch and B ch of SG.
4. Reverse the DY, and adjust coarsely the purity magnet so
that a green raster positions in the center of screen.
5. Adjust the tilt of DY, and fix lightly with a clamp.
Note: “TILT” shall be set at 128.
Note: “TILT” shall be set at 128.

Landing Fine Adjustment
1. Put the set inside the Helmholtz coil. (“LCC SW” = “140”)
2. Input the single green signal and set the CONT control to
2. Input the single green signal and set the CONT control to
MAX.
Note: After the W/B adjustment with 9300K, measure an aver-
age of
Σ
Ik when a full white signal is entered in the CONT
MAX/BRT CENT status. Then make adjustment so that
the specified screen can be attained after aging for 2 hours
with Ik equivalent to 30% of the average value.
the specified screen can be attained after aging for 2 hours
with Ik equivalent to 30% of the average value.
3. Demagnetize the metal part of the chassis with the hand de-
gausser and coil degausser, and the CRT surface with the
hand degausser.
Input AC 230V to AC IN, turn on and off the power to per-
form auto degaussing. (Perform auto degaussing by setting
“MON CON REG2”=152. Return to the original value after
use.)
Demagnetize the CRT surface with the hand degausser

This model has an automatic earth magnetism correction
function by using an earth magnetism sensor and a LCC coil.
When using a hand degauss while monitor (LCC coil) is be-
ing operated, it sometimes gets magnetized, and the system
may not work properly as a result.

4. Attach the wobbling coil to the designated part of the CRT
neck.
5. Attach the sensor of the landing adjustment unit on the CRT
surface.
6. Adjust the DY position and purity, and the DY tilt, and land-
ing of the center and 4 corners with the landing checker.

Moving the “LCC_NS” , adjust the landing at the Y end.
•
Adjust the landing by moving “LCC NS”, “LCC LT”,
“LCC LB”, “LCC RT” and “LCC RB”. However, the reg-
ister adjustment must be limited within the following
range.
