The light source, metal halide lamp, in the LCD projector emits small amounts of UV-Radiation.
NOTE TO SERVICE PERSONNEL
UV-RADIATION PRECAUTION
UV-Radiation and Medium Pressure Lamp Precautions
1. Be sure to disconnect the AC plug when replacing the lamp. 2. Allow one hour for the unit to cool down before servicing. 3. Replace only with same type lamp. Type CLMPF0042DE01 rated V/265W. 4. The lamp emits small amounts of UV-Radiation, avoid direct-eye contact. 5. The medium pressure lamp involves a risk of explosion. Be sure to follow installation instructions described below and handle the lamp with care.
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.
Lamp Replacement
Note:
Since the lamp reaches a very high temperature during units operation replacement of the lamp should be done at least one hour after the power has been turned off. (to allow the lamp to cool off.) Installing the new lamp, make sure not to touch the lamp (bulb) replace the lamp by holding its reflector 2. [Use original replacement only.]
3. Do not operate for more than 2 hours with the enclosure removed.
1 Lamp 2 Reflector
DANGER ! Never turn the power on without the lamp to avoid electric-shock or damage of the devices since the stabilizer generates high voltages at its start.

CONVERGENCE AND FOCUS ADJUSTMENT
» Start the convergence and focus adjustments with the top cabinet and the signal shield removed but the power on. Use the remote control gun to adjust the image. Take the following procedures. 1. Focusing the projection lens
(A) Replacing all the 3 LCD panels 1. Before replacing all the 3 LCD panels, project an image on the screen and bring it into focus. 2. 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 is affected. In other words, a short-distance image (40 WIDE, for example) may get out of the focus range, or a long-distance image (300 WIDE, for example) may come out of focus.
(
)
(B) Replacing 1 or 2 of the 3 LCD panels 1. 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. 2. 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. (If the distance has been changed or the projection lens readjusted, repeat the above steps 1 and 2.)
2. Adjusting the G-LCD panel
(A) Focus adjustment. (Make this adjustment on the white-only screen.) 1. Right-and-left focus adjustment (Y direction) . Loosen the lock screws "b" and "c" and insert the eccentric screwdriver into the notch and hole "b". Turn the screwdriver until the right and left halves on the screen get into focus. First get the right and left halves in balance. Then improve the accuracy while making the adjustment 2 below. 2. Top-center-bottom focus adjustment (X and Z directions). Loosen the lock screws "a" and "c" and insert the eccentric screwdriver into the notch and hole "a" or "c". Turn the screwdriver until the top, center and bottom on the screen get into focus. In adjusting this topto-bottom focus, temporarily tighten the lock screw "b" to fix the Y direction adjustment. 3. Repeat the above steps 1 and 2 to finely adjust the focus. Finally tighten up all the lock screws.
(
)
Note : 1 Carefully proceed with the focus adjustment because the adjusting directions are correlated. 2 In adjusting the convergence and focus, do not move the projection lens zoom and focus rings until the end of all the adjustments. (B) Convergence adjustment » The G-LCD panel has no convergence adjustment mechanism. Use this panel as convergence adjustment reference.
3. B-LCD panel adjustment (the same for the R-LCD panel)
(A) Focus adjustment » 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. (B) Convergence adjustment » Use a crosshatch pattern signal for this adjustment. Make the adjustment just for the G-colour and the relevant colour. (1) Loosen the convergence lock screw "d". (2) With the G-LCD panel's screen center as reference, adjust the B-LCD panel in the X, Y and Z directions. (3) Finally tighten up the convergence lock screw "d".
17
XG-NV1E XG-NV1EA Note : 1 The eccentric cam is used for convergence adjustment. This means that the cam's turning and the linear movement are not always uniform. 2 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.

Replacing the LCDs
With the top cabinet removed (1) Remove the output shield. (2) Disconnect the LCD flat cable from the output PWB connector. (3) Remove the lock screws "b" and "c". Detach the R/B adjusting plate or the G adjusting plate together with the LCD panel. (4) Separate the LCD panel from the adjusting plate. (5) Mount a new LCD panel in the reverse order of the above steps (1), (2), (3) and (4). ~ Readjust the convergence and focus. Note that the G LCD panel needs no convergence adjustment and has a small adjustment range in the Z direction.
