ADJUSTMENT INSTRUCTIONS 4-2. Adjustment 1. Application Object (1) Select EZ Adjust 3. CUT-OFF, by pressing the ADJ key on the SVC Remote control. When it enters to adjustment mode, the pattern from a signal generator is being selected, it becomes with Normal image 16:9 and the CUT-OFF DRIVE data setting 31. (2) Connect the oscilloscope ground lead to GND on the CPT board and the probe to the GK pin connector of the CPT socket.
ADJUSTMENT INSTRUCTIONS 5-4. Raster H-center(H.CENTER) Adjustment 7. White Balance Adjustment Select 77. H Postion in the adjustment mode and adjust until left and right screen are symmetrically equal. Perform the screen adjustment first. Color Temp must be adjusted from Medium Mode. (The image condition must be adjusted from Normal condition) Manual adjustment is also possible by the following sequence. 5-5.

PURITY & CONVERGENCE ADJUSTMENT Caution: 5. Reconnect the internal degaussing coil. Convergence and Purity have been factory aligned. Do not attempt to tamper with these alignments. However, the effects of adjacent receiver components, or replacement of picture tube or deflection yoke may require the readjustment of purity and convergence. 6. Position the beam bender locking rings at the 9 o'clock position and the other three pairs of tabs (2,4 and 6 pole magnets) at the 12 o'clock position.
PURITY & CONVERGENCE ADJUSTMENT 2 .ADJUST BEAM BENDER 2 POLE MAGNET TO GET FOUR EQUAL COLOR CIRCLES 1.ADJUST YOKE Z-AXIS FIRST TO GET EQUAL BLUE COLOR CIRCLES MAGNETS RED RED 8. Referring to above, perform the following two steps: a. Adjust the yoke Z-axis to obtain equal blue circles. b. Adjust the appropriate beam bender tabs to obtain correct purity (four equal circles). 9. After correct purity is set, tighten the yoke clamp screw and remove the two screen magnets. 5.
