Scheimpflug Adjustment (Diagonal image focusing)

With the diagonal image focusing corrections, it is possible to obtain uniform focus for the total projected image.

These corrections must be repeated for each colour. The Diagonal image focusing is repeated 3 times, first for green, then for red and then for blue.

First, be sure that the CRT projection angle is correctly adjusted, otherwise it is not possible to obtain proper overall focus of the image.

Press ENTER to start the green adjustment.

Press EXIT to return to CRT Projection Angle Adjustment.

Adjustment procedure :

DIAGONAL IMAGE FOCUSING

1.TURN THE SCREW MARKED TO FOCUS THE IMAGE DIAGO- NALLY from LEFT (bottom) TO RIGHT (top).

2.TURN THE SCREW MARKED TO FOCUS THE IMAGE DIAGO- NALLY from LEFT (top) TO RIGHT (bottom)

Example : diagonal focusing of the green image.

Equalize diagonally the focus from left (bottom) to right (top) by turning screw A3 of the projected colour.

Equalize now diagonally the focus from left (top) to right (bottom) by turning screw A4 located under the green lens.
