6. Adjust the DY position and purity, and the DY tilt, and landing
of the center and 4 corners with the landing checker.
After adjustment, set “LCC SW” to “13”.
• Write terrestrial magnetism sensor reading VX and VY to
“LCC VX” and LCC VY” respectively. Adjust the landing by
moving “LCC NS”, “LCC LT”, “LCC LB”, “LCC RT” and
“LCC RB”. However, the register adjustment must be limited
within the following range.
“LCC NS” 128 ± 45
“LCC LT”, “LCC LB”, “LCC RT”, “LCC RB”
128 ± 40
Save the service data.
* Adjustment and measurement should be made at the points one
inch inside the fluorescent screen.
7. Tighten DY screw.
Note:Torque 22 ± 2 kg.cm (2.2 ± 0.2 Nm) auto degauss it.
8. For the up/down swing, swing the DY and insert a wedge so
that the up and down pins are equal at the top and bottom.
Adjust the H.TRP VR of DY so that the horizontal trapezoid is
equal at the left and right. Insert the wedge firmly so that the DY
does not shake.
9. Check the landing of each corner, and if it does not satisfy the
specification, adjust the landing of four corners using “LCC
LT“, “LCC LB”, “LCC RT” and “LCC RB”.
However, the register adjustment must be limited within the
following range.
“LCC NS” 128 ± 15
<Specifications>
Adjust so that the green is within the
specification given right.
4 corner adjust target : within ± 1
The red and blue must be within the
specification given right with respect to
the green.
A difference between red and blue must
be within the specification given right.
“LCC LT”, “LCC LB”, “LCC RT”, “LCC RB”
128 ± 45
After adjustment, save the service data.
10. Remove the sensor and wobbling coil.
11. Switch the signal to R.G.B., and check that each color is pure.
12. Check that the DY is not tilting, and fix the purity Mg with a white pen. Fix
wedges with RTV.
