NOTE TO SERVICE: PERSONNEL
UV-RADIATION PRECAUTION
;///////////////////
The light source, metal halide lamp, in the LCD
projector emits small amounts of UV-Radiation.
AVOID DIRECT EYE AND SKIN
EXPOSURE.
To ensure safety please adhere to the following:
1.
Be,
sure to wear sun-glasses when servicing the
projector with the lamp
turned “on” and the top
enclosure removed.
2. Do not operate the lamp outside of the lamp
housing.

Since small amounts of UV-Radiation are emitted
from an opening between the duct cover and the
lamp housing, it is recommended to place the LENS
CAP on the opening during servicing to avoid eye

l
Allow at least 10 cm of space between the cooling fan (exhaust vent) and the other nearest
wall or obstruction.

If the cooling fan becomes obstructed, a protection device will automatically turn off the
projector lamp.
This

wall outlet and wait 10 minutes. Then turn on the power by plugging the cord back in. This
will return the projector to its normal mode.

The laser pointer on the remote control emits
a laser beam from the laser light window

emitted is a class II laser; therefore, do not
look
into the laser window or shine the laser
beam on yourself or other people. The two

Before replacing all the 3 LCD panels, project an image on the screen and bring it into focus.
Replace the panels with new ones. But until the focus has been completely readjusted, be careful not to
change the distance between the set and the screen, nor to move the projection lens focus and zoom
rings.
If the focus is readjusted with a different positional relation, the relation between the projection distance
and the screen size
get out of the focus range, or a long-distance image (300 WIDE, for example) may come out of focus.
In adjusting the focus after replacement of one or two LCD panels, project an image on the screen and
turn the projection lens focus ring to get the non-replaced LCD panel into focus.
But until the focus has been completely adjusted for the new LCD panels, be careful not to change the
distance between the set and the screen, nor to move the projection lens focus and zoom rings.

Carefully proceed with the focus adjustment because the adjusting directions are correlated.

Take the same procedure as for the G-LCD panel focus adjustment. Note that the adjustment range is
small in the Z direction. If the convergence is quite different between the B-LCD and G-LCD panels,
roughly adjust the convergence first and then the focus.

This model is not equipped with the LCD image adjustment mechanism. This is because the dichroic
prism is used for image formation. When the LCD panels all get into the best focus, the images are
almost completely converged.
