For every point on the screen, each of the three beams has a specific correction possibility in both horizontal and vertical
planes. To achieve this, three levels of adjustment are available in the Service Mode. The unit is also equipped with an
alignment grid pattern generator incorporated on the convergence circuit board.
Trois niveaux de réglages sont accessibles dans le mode service et permettent à partir d'une mire de quadrillage générée
par les circuits de convergence d'apporter une correction horizontale et verticale aux trois faisceaux de couleur.
Für jeden Punkt des Bildschirmes und für jeden der drei Katodenstrahlen ist eine spezielle Korrektur sowohl horizontal als
auch vertikal, möglich. Im Service-Mode sind drei Ebenen (Level) für den Abgleich der Konvergenz verfügbar.
Das Gittertesbild wird von der Konvergenzschaltung erzeugt.
Per ogni punto dello schermo, ognuno dei tre raggi ha una specifica possibilità di correzione in entrambi i piani orizzontale e
verticale. A questo scopo, sono disponibili tre livelli di regolazione in Service Mode. L'unità, inoltre, dispone di un generatore
di griglia per l'allineamento, incorporato sulla piastra convergenza.
Tres niveles de ajustes están disponibles en Modo Servicio y permiten a partir de una mira de cuadrícula generada por los
circuitos de convergencia, efectuar correcciones especificas en los planos horizontal y vertical para cada uno de los tres
haces.

DESCRIPTION OF POSSIBLE CONVERGENCE PROBLEMS
The Rearprojector should be warmed up at least thirty minutes
RED AND BLUE PICTURE SHIFTED
RED AND BLUE PICTURE
Static Adjustments
SHIFTED
- Select "CONVERGENCE" in the Install Menu.
- Correct the shift with the keys of navigation in the menus of convergences and
autoconvergences (if the Rearprojector is equipped with this function).

Auto convergence
Red convergence
Blue convergence
To go to Auto convergence menu,
press
or
.
- If the required alignment is difficult make the adjustments using the magnetic centring
rings on the red and blue tubes.
- Firstly, unlock the lightly glued centring rings and then make the necessary
adjustments.
- Once aligned the rings must be locked using a lightweight glue or varnish in order that
subsequent adjustments can be made.
See adjust table p. 19-20.
BORDERS OR SMALL AREAS
CENTRAL AREA IS CORRECT. BORDERS OR A SMALL AREAS ARE VERY
ARE VERY POORLY ALIGNED
POORLY ALIGNED
A - GREEN geometry is correct :
- Only adjust the Red and Blue geometry using Level 3 of the convergence menu, don't
touch the green geometry !
B - GREEN nedds a small adjustment :
- First adjust the Green geometry, then align the Red and Blue geometry using Level 3
convergence menu.
SMALL ADJUSTMENTS ARE NECESSARY
SMALL ADJUSTMENTS
EVERYWHERE.
GREEN GEOMETRY IS CORRECT
The some convergence lines are incorrect, but Green geometry is correct.
- Align Red and Blue geometry using convergence menu Level 1 or Level 2.
- Correct the borders if needed using convergence menu Level 3, don't touch the green
geometry !.
GREEN GEOMETRY
GREEN GEOMETRY IS POORLY ALIGNED
IS POORLY ALIGNED
A - BLUE or RED Geometry is correct :
- Enter the convergence menu Level 2 and press the YELLOW button on the RCU. The red,green
and blue grids are displayed but only GREEN geometry can be aligned.
- Adjust the Green geometry to superimpose it on either the Red and/or Blue grid, to ease
alignment select the best-converged colour and cover the others lens.
Red, Blue and Green
B - BLUE or RED is poorly aligned :
- Enter the Service Mode and select the GEOMETRY menu
- Adjust the alignment of the H/V Amplitudes and E/W Correction settings, if the geometry does not
respond to adjustment then:
- Select convergence menu Level 2 and press the YELLOW button on the RCU to select Green
(5X5) alignment routine.
- Check that the centre point of the green grid is exactly central
- Align the grid pattern borders exactly with the screen borders.
- Align the outer edge of the picture if necessary, using convergence menu Level 3.
- Align RED convergence using menu Level 2 and if necessary the borders with Level 3.
- Repeat the above process for BLUE alignment.
