Crt Projection Angle Adjustment - Barco R9040014 Installation Manual

Installation Adjustment Mode

CRT Projection Angle Adjustment

The projection angle of the red and blue CRT's is dependent on the desired size of the projected image. If the centers of green, blue
and red do not coincide, the CRT projection angle must be adjusted.
Note
Never try to correct this misalignment with the shift correction or the static convergence controls.
These controls may only be applied to correct small errors which cannot be corrected by the CRT angle adjustment.
Note: The Horizontal Shift and Vertical Shift for Red and Blue should be set near 50%.
Be sure that the rasters are centered on the CRT faceplate.
How to adjust the Projection angle:
1 Press ENTER to start the CRT angle adjustment procedure (Menu 1 ).
2 Press ENTER to continue with the crosshair alignement (Menu 2).
3 Loosen bolts A, B, C and D to pivot the red CRT until the center of the Red image and the center of the Green image
coincide (Menu 3) .
4 When the angle of the red CRT is corrected, tighten the four bolts.
5 Press ENTER to continue with the alignement of the blue CRT.
Press EXIT to return to the CRT projection angle adjustment menu.
6 Loosen bolts E, F, G and H (Image 1 )to pivot the blue CRT until the center of the Blue image and the center of the Green
image coincide (Menu 4).
When the angle of the blue CRT is corrected, tighten the four bolts.
Press ENTER to continue with the diagonal focusing menu.
