SERVICE ADJUSTMENTS
(2) Contrast should be set center and the other controls should be set standard.
(3) Push the “
SERVICE ONLY
” switch on the CONVERGENCE P.W.B. to set the digital convergence unit to the
adjustment mode.
(4) Phase
set
1) Press the [
REVEAL
] key on R/C to display the green cross-hatch pattern.
2) Press the [
CH
Ⅰ
/
Ⅱ
] key to recall the phase DATA on screen.
PAL 100i mode PAL 50p mode NTSC 60p mode
3) If phase data is not same as above, change the DATA by using the following R/C keys.
Press [
4
] or [
6
] key to adjust the PH-H
Press [
2
] or [
5
] key to adjust the PH-V
Press [

] key to exit from phase mode.
5) Press [
INDEX
] key on R/C twice to write the data into ROM.
6) Push the “SERVICE ONLY” switch on the CONVER P.W.B. twice to exit from adjustment mode of the
digital convergence unit.
(4) Change to PAL50p mode (Set DCU the PAL50p mode) and repeat procedure (2)-(3) for PAL50p mode.
(5) Change to NTSC mode (Set DCU to the NTSC mode) and repeat procedure (2)-(3) for NTSC mode.
2.4 BEAM ALIGNMENT
Preparation for adjustment
(1) Pre-heat 30 minutes or more before the adjustment.
(2) The static convergence data should be cleared.
(3) Raster inclination should be adjusted. Optical focus should be coarsely adjusted.
(4) Contrast should be set MAX and the other control should be set Center.
(5) Receive the NTSC cross-hatch pattern signal or Dot pattern signal.
(6) Discharge static charge from metallic parts on PRT NECK by using Short-clip-JIG.
Adjustment procedure
(1) Green (G) tube alignment: Short-circuit 2P sub-mini connectors on the red ( R ) and blue (B) CPT P.W.B.s and
project the only green beam.
(2) Set the G tube beam alignment magnet to the cancel state as shown on right.
