Use AUDIO button to select a Sub Function Use the VIDEO button to select an Adjustment Item. Use the ADJUST buttons to change data.

E. FINE CONV (Press 4)

Sub Functions 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, for Fine Raster Corrections. FINE RED. a White Crosshatch is displayed, for Fine Red Convergence Adjustments. FINE BLUE. a White Crosshatch is displayed, for Fine Blue Convergence Adjustments. Cursor In the Fine mode a Cursor is added to the Crosshatch. The ENTER button toggles the Cursor between two modes: MOVE (blinking Cursor). use the ADJUST 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.
Cursor Coordinates Specific intersections in the Crosshatch are assigned vertical and horizontal coordinates. These are shown in the above diagram. The Cursor can only be moved to those positions that have coordinates assigned. If the Cursor is at coordinates outside the screen area, the Cursor will not be visible. Use the ADJUST buttons to move the Cursor to an intersection on the screen.

Page 22

Display The on-screen display changes in the Fine mode, as shown below. The display shows the vertical and horizontal data for the current Cursor Position, and the horizontal and vertical coordinates for that position.
F. Saving Data and Exiting the Convergence Mode
Press MENU twice to exit the Convergence mode, data is automatically saved. Note: If power is interrupted prior to properly exiting the Convergence Mode, changes in adjustment data will not be saved.

CHIP PARTS REPLACEMENT
Some resistors, shorting jumpers (0 Ohm resistors), ceramic capacitors, transistors and diodes are chip parts. The following precautions should be taken when replacing these parts. Cautions: 1. Use a fine tipped, well insulated soldering iron (approximately 30 watts), and tweezers. 2. Melt the solder and remove the chip parts carefully so as not to tear the copper foil from the printed circuit board. 3. Discard removed chips; do not reuse them. 4. Do not apply heat for more than 3 (three) seconds to new chip parts. 5. Avoid using a rubbing stroke when soldering. 6. Take care not to scratch, or damage the chip parts when soldering. 7. Supplementary cementing is not required. Chip Parts Removal (Resistors, Capacitors, etc.) 1. Grasp the part with tweezers. Melt the solder at both sides alternately, and remove one side of the part with a twisting motion. 2. Melt the solder at the other side and remove the part. Chip Parts Removal (Transistors) 1. Melt the solder of one lead and lift the side of that lead upward. 2. Simultaneously melt the solder of the other two leads and lift the part from the PCB.
Replacement 1. Presolder the contact points on the circuit pattern. 2. Press the part downward with tweezers and apply the soldering iron as shown.
