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 Conver- gence 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 dis- played, 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 Cross- hatch. See Figure 2-6. The ENTER button toggles the Cursor between two modes:

•MOVE (blinking Cursor) .... use the AD- JUST buttons to select any of 64 points on the Crosshatch.

•ADJUST (Non blinking Cursor) .... the ADJUST buttons adjust the active color at the current Cursor position, horizontally or vertically.

The on-screen display changes in the Fine mode, as shown in Figure 2-7. The display shows the verti- cal and horizontal data for the current Cursor Posi- tion, and the horizontal and vertical coordinates for that position.

Saving Data and Exiting the Convergence Mode Press MENU twice to exit the Convergence mode. Data is automatically saved at this time.

Alignment Data Storage Locations

Data accessed in the Convergence Adjustment Mode is stored in IC8D01 located on the PCB-Signal. Re- placement PCB’s are supplied pre-aligned so that only fine adjustments should be necessary after re- placement. All other service alignment data is stored on the PCB-E2P located on the DM assembly. When replacing the DM assembly, retaining the original PCB-E2P will minimize the need for any realign- ment.
