Measure the hight voltage level at the anode cap. High voltage should be within the limit as above. If the high voltage needs adjustment use the following procedure.

PROCEDURE

1.Turn the power off and disconnect the AC line cord from the power source.

2.Turn the power on after connecting high voltage Probe.

3.Using the jig, adjust the high voltage to the specification.

* High Voltage Adjustment PROCEDURE using Softjig

Select matching model name in ÒModelÓ field.

Select Ò @7: Zero BeamÓ in menu after selecting ÒExtra 1Ó

Adjust high voltage using control bar after selecting ÒHV MINÓ

Turn the power off/on after adjustment finished.

Check the high voltage has been fixed with adjusted value after reselecting Ò@7: Zero BeamÓ.

4-2-3 CENTER RASTER

Adjust SW401 so that the back raster comes to the center when you apply each basic mode for 15Ó and 17Ó.

4-2-4 Centering

Centering means to position the center point of the display in the middle of the display area. Horizontal size and position and vertical size and position control the centering of the display.

Adjust the horizontal size and vertical size to their optimal settings: 306 mm (H) x 230 mm (V) for 17Ó, 267 mm (H) x 200 mm (V) for 15Ó.

Adjust the horizontal position and vertical position to ² 4.0 mm of the center point of the screen.

A-B ² 4.0 mm.

C-D ² 4.0 mm.
