11. Adjust red centering magnets until the pattern cen-

4. Adjust centering magnets so that the center of the

ter is at the appropriate distance as indicated on figure. 12. Enable digital convergence by changing DAC MUTE from 01 to 00. 13. Set VIDEO �C_OFF� DAC from 02 to 00. Following the adjustment, make sure that all deflection coils are pushed completely toward the CRT cones and that all screws are tightened.

pattern get aligned with screen frame center. 5. Adjust VDEF �V-AMP� DAC until vertical size is proportional on top and bottom. 6. Set DAC MUTE from 01 to 00 (disabling digital convergence). 7. Set VIDEO �C_OFF� DAC from 01 to 00

17.4. NTSC Vertical linearity adjustment
(V-C and V-S)
This adjustment is intended to make the picture vertically proportional (top, center and bottom) for NTSC mode NOTE:

1080i, 480p, 480i pattern can be obtained from Panasonic�s TU-DST51 set-top box DTV decoder. 1. Apply a NTSC pattern that lets adjust the image to correct vertical linearity (see above note). 2. Set VIDEO �C_OFF� DAC from 00 to 01 (to project only green). 3. Set DAC MUTE from 00 to 01 (disabling digital convergence). 4. Adjust centering magnets so that the center of the pattern get aligned with screen frame center. 5. Adjust VDEF �V-C� and �V-S� DAC until vertical size is proportional on top and bottom. Confirm to correct linearity in the middle of the screen. 6. Set DAC MUTE from 01 to 00 (disabling digital convergence). 7. Set VIDEO �C_OFF� DAC from 01 to 00

17.7. HD 1080i Vertical size adjustment (V
AMP)
This adjustment is intended to correct the vertical size of the picture for HD 1080i mode. NOTE:

1080i, 480p, 480i pattern can be obtained from Panasonic�s TU-DST51 set top box DTV decoder. 1. Apply a HD 1080i pattern that lets adjust the image to correct vertical size (see above note). 2. Repeat NTSC vertical size adjustment from step 2

17.5. HD 1080i Vertical linearity adjustment (V-C and V-S)
This adjustment is intended to make the picture vertically proportional (top, center and bottom) for HD 1080i mode NOTE:

1080i, 480p, 480i pattern can be obtained from Panasonic�s TU-DST51 set-top box DTV decoder. 1. Apply a NTSC pattern that lets adjust the image to correct vertical linearity (see above note). 2. Repeat NTSC vertical linearity adjustment from step 2

17.6. NTSC Vertical size adjustment (VAMP)
This adjustment is intended to correct the vertical size of the picture for NTSC mode NOTE:

17.8. NTSC ZOOM Vertical size adjustment (V AMP)
This adjustment is intended to correct the vertical size of the picture for NTSC ZOOM mode NOTE:

1080i, 480p, 480i pattern can be obtained from Panasonic�s TU-DST51 set-top box DTV decoder. 1. Apply a NTSC pattern that lets adjust the image to correct vertical size (see above note). 2. Set VIDEO �C_OFF� DAC from 00 to 01 (to project only green). 3. Set DAC MUTE from 00 to 01 (disabling digital convergence).

1080i, 480p, 480i pattern can be obtained from Pana-

sonic�s TU-DST51 set top box DTV decoder. 1. Apply a NTSC pattern that lets adjust the image to correct vertical size (see above note) 2. Change aspect to ZOOM mode. 3. Repeat NTSC vertical size adjustment from step 2
