5. Beam alignment
Adjustment preparation
(1) Adjust at least 30 minutes after turning on power switch.
(2) Demagnetize the CRT mounting bracket.
(3) Raster inclination, centering, horizontal and vertical amplitudes and optical focus adjustment should be
completed.
(4) Set video conditions to standard mode.
(5) Receive cross-hatch signals. (Use of internal cross-hatch signals allowed.)
Adjustment procedure
(1) Green (G) tube beam alignment adjustment. Apply covers to the R and B lenses and project only green light.
(2) Put Green (G) tube beam alignment magnet to the cancel state as shown below.
(3) Turn the Green (G) static focus (Focus Pack) counterclockwise all the way and make sure of position of cross-
hatch center on screen. (Halo state.)
(4) Turn Green (G) static focus (Focus Pack) clockwise all the way. (Blooming state.)
(5) Turn two magnets forming alignment magnet in any desired direction and move cross-hatch center to position
found in (3).
(6) If image position does not shift when Green (G) static focus (Focus Pack) is turned, Green (G) beam alignment
has been completed.
(7) If image position shifts when Green (G) statis focus (Focus Pack) is turned, repeat (2)-(6).
(8) Conduct beam alignment for Red (R) focus, Blue (B) focus.
(9) Upon completion of adjustment, fix beam alignment magnets with white paint.
6. Beam shape adjustment
Adjustment preparation
(1) The beam alignment should have been completed.
(2) The raster inclination, centering, horizontal/vertical amplitude and optical focus adjustments should have been
completed.
(3) Set video conditions to factory reset.
(4) Input the dot signal.
Adjustment procedure
(1) Green CRT beam shape adjustment. Apply covers to the R and B lenses and project only green light.
(2) Turn the green static focus fully clockwise. (Blooming.)
(3) Make the dot at the screen center a true circle using the 4-pole magnet as shown below.
(4) Also adjust the Red and Blue CRT beam shapes according to the steps (1) to (3).
(5) After the adjustment is completed, return R, G and B static VRs to the Just focus point.
