The blanking correcions are only enabled during the blanking adjustments. Horizontal Phase Adjustment Push the control disc up or down to highlight H PHASE on Geometry menu and the press ENTER. Note : No horizontal phase adjustment is available on the internal # pattern. For external sources : f the raster shift is correctly adjusted, the H Phase text box is projected in the middle of the aster. At that moment, the “><” icon indicates the middle of the raster. Adjust the H Phase control until the middle of the projected image is equal with the middle of >< icon. Note : -If the genlocked pattern was selected, the external source will be displayed. bar scale and a number indicator (between 0 and 100) on the screen give a visual indication of the horizontal phase adjustment. Push the control disc to the right to correct Push the control disc to the left to correct 6-5 Raster Shift Adjustment The green raster must be centered both horizontally and vertically on the center of the CRT surface. To center the green raster, look into the green lens and use the control disc to move the raster. CAUTION It is necessary to look into the lenses to perform these adjustments. To avoid eye discomfort while looking into the lenses, reduce the contrast and gradually increase the brightness level until the raster becomes visible on the face of the CRT. To start the adjustment, use the control disc to highlight Raster shift and press ENTER to display the green raster on the phosphor. Press EXIT to return to the Geometry menu. Note : Horizontal and Vertical shifts for Red and Blue should end up with a setting close to 50%. If these settings are significantly greater or lesser than 50%, contact a RUNCO authorized service technician. 6-6 Left-Right (east-west) Adjustments Left-right and center adjustments affect only the vertical lines of the projected image. To start up the left-right and center adjustments, follow the next procedure : Push the control disc up or down to highlight LEFT-RIGHT (E/W) on the geometry menu and then press ENTER. Only the green image is displayed while making left-right adjustments. The red and blue images will automatically be corrected in the same manner. Convergence corrections are automati cally disabled for the duration of these adjust ments. The following adjustments can be executed -vertical centerline bow -vertical centerline skew -side keystone (left - right) -side bow (left - right) All adjustments are indicated on the screen with the function name, a bar scale and a number between 0 and 100. Adjust the next alignments until the vertical lines are straight. To enter an alignment, push the control disc up or down to highlight a function and press ENTER to activate this function. Press EXIT to return. 6-7 Top-Bottom (north-south) Adjustments Top-Bottom and center adjustments affect only the horizontal lines of the projected image. To start up the Top-Bottom and center corrections, follow the next procedure : Push the control disc up or down to highlight TOP-BOTTOM (N/S) on the geometry menu and then press ENTER. Only the green image is displayed while making top-bottom adjustments. The red and blue images will automatically be cor rected in the same manner. Convergence corrections are auto matically disabled for the duration of these adjustments. The following adjustments can be executed -Horizontal centerline bow -Horizontal centerline skew -Top bow -Top keystone -Bottom bow -Bottom keystone All adjustment are indicated on the screen with the function name, a bar scale and a number between 0 and 100. Adjust the next alignments until the vertical lines are straight. To enter an alignment, push the control disc up or down to highlight a function and press ENTER to activate this function. Press EXIT to return. 6-8 Size Adjustment Push the control disc up or down to highlight SIZE on the Geometry menu and then press ENTER. ENTER will select size adjustment. EXIT returns to random access adjustment mode menu. ADJUST returns to operational mode. Adjust the horizontal size by pushing the control disc to the right or to the left until the exact image width is obtained. Adjust the vertical size by pushing the control disc up or down until the exact image height is obtained. Note : -If the internal # pattern was selected, this pattern remains on the screen. -If the genlocked pattern was selected, the external source will be dis played. A bar scale and a numeric indicator help to gauge the size adjustment. EXIT will return to Geometry. 4 X 3 -Use horizontal size to make image fit width of screen, then use vertical size to make image fill height (circle is round). On a wide format (1:78:1 or 1.85) screen, adjust width of image 1.33 X the height of the screen. Adjust the vertical size to fill the height. WS -Use horizontal size to fill width of screen, then use vertical size to make circle round (use blanking to crop excess image top and bottom.) This is not necessary if you are using a 4 X 3 format screen....
