The width of the projected picture of the picture tube
R762104-2, -5 and -6 is larger than its replacement picture
tube R762431-2, -5 and -6.
To enlarge the width of the projected picture for the
replacement part, short-circuit the corresponding WIDTH
coils on the Deflection Switching module.
ATTENTION: before proceeding to the short-circuit of the
respective WIDTH Coil, activate CONVERGENCE OFF in
the SERVICE-Menu to switch the Convergence adjust-
ments in their mid-position.
WIDTH Adjustment: adjust the WIDTH-Coils of the not
replaced picture tubes for equal picture Width.

The adaptation of the module consists of a readjustment of

transistor Q804)
Adjust the potentiometer P802 for a pulse duration of the
Pulse 2 of 2.5us on emitter of transistor Q804.

Scheimpflug Adjustment (Diagonal image focusing)
What has to be
done
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 color. 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, other ise 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.
Loosen first the security scre s (see images opposite and
above.)
Example : diagonal focusing of the green image.
Equalize diagonally the focus from left (bottom) to right
(top) by turning scre A3 of the projected color.
Equalize no diagonally the focus from left (top) to right
(bottom) by turning scre A4 located under the green lens.
Repeat the same procedure for the red and blue image
using the corresponding scre s.
To optimize the image focusing, repeat the optical lens
focusing.
When the scheimpflug corrections are correctly adjusted,
secure this position by fastening the security scre s on
both sides of each lens.
Warning : When the security screws are tightened, it is not
possible to change the scheimpflug correction.
After finishing the Installation Adjustment Procedures, the
main menu returns on the screen. You are no able to start
the alignment procedure for the projector.
For detailed information about these adjustments, please
refer to the O ner's Manual of the projector.
