On Screen Display Position Adjustment Mode Activation 1) Select 480i or 1080i source. 2) Press MENU-0-3-8-8 2-4 Convergence Adjustment Mode The Convergence mode is used to perform raster geometry correction and convergence adjustments. These adjustments must be made in both the SD (NTSC 480i) and HD (1080i) modes. Note: Before activating the Convergence mode, turn “Video Mute” Off. The internal crosshatch pattern will not be displayed with “Video Mute” On, only a blue background is displayed. Convergence Mode Activation 1. Press MENU-0-3-5-9 2. When the Convergence Mode is activated, this display appears on a Green Crosshatch. See Figure 2-5. MODE FUNCTION SUB-FUNCTION SD or HD SD COARSE GREEN 0 HSTA 00 ITEM ABREV DATA NO.

NOTE: When Item “1 HVOL” is selected the screen goes black except for the data display. This occurs since a black screen is required when making the HV Regulation adjustment. COARSE CONV (Press 5) There are four Sub Functions in the Coarse mode, COARSE GREEN, COARSE RED, COARSE BLUE and DF. • COARSE GREEN .... used to make Coarse Raster Geometry Adjustments. • COARSE RED ... used to make Coarse Red Convergence Adjustments. • COARSE BLUE ... used to make Coarse Blue Convergence Adjustments. • DF ... used to preset data values controlling the Dynamic Beam Focus circuit drive signal. 2-5 1) Use AUDIO button to select a Sub Function 2) Use the VIDEO button to select an Adjustment Item. 3) Use the ADJUST buttons to change data. FINE CONV (Press 4) This mode is used to perform Fine Raster Correction, and Fine Red and Blue Convergence Adjustments. There are three Sub Adjustment Functions, selected with the AUDIO button: • FINE GREEN .... a Green Crosshatch is displayed, to make Fine Raster Corrections. • FINE RED .... a White Crosshatch is displayed, to make Fine Red Convergence Adjustments. • FINE BLUE .... a White Crosshatch is displayed, to make Fine Blue Convergence Adjustments. In the Fine mode a Cursor is added to the Crosshatch. See Figure 2-6. The ENTER button toggles the Cursor between two modes: • MOVE (blinking Cursor) .... use the ADJU...
