MP8 CRT Installation
Page 5
Supplemental Information
Alignment of Yoke Rotation (if needed)
NOTES:
X-RAY LEVELS ARE EXTREMELY LOW, HOWEVER WHEN
ALIGHNING THE YOKE THE BEAM LIMIT CURRENT SHOULD BE
KEPT LOW (CONTRAST < 30 ON THE BAR MENU).
DO
NOT
TOUCH THE WINDINGS OR TERMINALS OF THE
DEFLECTION YOKE. CONTACT WITH THE WINDINGS OR
TERMINALS POSE A SERIOUS SHOCK HAZARD.
To align the new CRT to the other two for minimum converge power and optimize
accuracy, you must readjust the mechanical rotation of the yoke.
•
Reset software for convergence values.
•
Remove the top white plastic shield.
•
Turn on the projector and display an internal crosshatch.
•
Rotate the Deflection Yoke (closest to the front of the CRT) to match the other
setup while looking at the center horizontal lines of a crosshatch.
•
Place a dab of hot melt on CRT and Yoke to insure that the deflection yoke
does not move.
•
Reattach the top plastic shield.
NOTE:
Upon completion, a full optical alignment may be
required.
