Replacing an NEC VT560 Projector (03-00060) in a 2000i-DVX

Use these instructions to replace the NEC VT560 projector in a 2000i-DVX. Note that you will reuse the screws, washers

and spacers that secure the original projector to the cabinet, so keep track of them. However, three replacement sets of

screws, washers and spacers are included in the kit.

To replace the NEC VT560 projector in a 2000i-DVX, complete the following tasks:

1. Remove the original projector (and projector plate) from the cabinet (this page).

2. Install the replacement projector in the cabinet (page 4).

3. Align the projected image (page 6).

4. Check projector settings (page 15).

1. If you need better access to the rear of the cabinet, retract the anti-tip feet and unlock the wheels by raising the caster

tab locks on each wheel. Then roll the unit away from the wall. Press the caster tab locks down to lock the wheels

again, and then extend the anti-tip feet.

2. Using the height-adjustment handle, raise the unit to allow easier access to the projector.

3. Shut down the computer, and then press and hold the Lamp Off button in the Control Panel until the screen turns black

(approximately three seconds). Release the button and the projector lamp powers off in 60 seconds.

4. Unplug the 2000i from the power outlet.

This kit contains:

• an NEC VT560 projector

• a T20 TORX® security key

• a 7/16" nut driver

• 3 TORX button-head screws, flat washers and split

washers (if required)

• 3 spacers (if required)

• 4 replacement tie wraps

•aProjector Mount Location Guide

Tools required (but not supplied):

• small wire cutters for snipping tie wraps

• a 3/16" or 5/32" flat screwdriver (for adjusting focus)

CAUTION Complete these procedures only with the assistance of another person, who must support the projector

while you remove the original projector and while you install the new one. Otherwise, the projector may

fall and sustain damage.

5. Switch the projector off, and then unplug the AC power, PC Control and RGB 1 IN connectors from the back of the

projector.

6. Using a pair of small wire cutters, snip the plastic tie wraps that secure the cables to the projector plate (if necessary).

7. While a second person supports the projector, use the security key to loosen and then remove the four button head

screws (and the accompanying flat and split washers) that hold the projector/projector plate assembly to the two sides

of the projector platform. Carefully collect and place the four screws and eight washers nearby, as you’ll need them

when you install the replacement projector.

IMPORTANT

Take note of the cable connectors as you disconnect them, as you’ll connect them to the same ports in

the replacement projector.

CAUTION

When using wire cutters to cut a tie wrap, be very careful not to gouge the adjacent cables.

CAUTION A second person must support the base of the projector during the entire removal process. Otherwise,

the projector could fall and sustain damage.

1. Remove the lens cap.

2. Set the new projector upside down on the table, and place the three spacers (removed in the previous procedure) over

the three holes in the base.

3. Place the projector plate over the three spacers, and then insert the three sets of TORX security button-head screws,

split washers and flat washers (removed in the previous procedure) through the slots in the plate and into the three

spacers. We recommend that you position the plate so that the slots are centered over the spacers.

4. Tighten the screws with the security key.

5. Note the Mount Location label on the projector (near the projector service label), and make sure you position the

replacement projector in the indicated number and letter mount positions. You can also find the number and letter

mount locations in the Projector Mount Location Guide provided with the replacement projector.

6. While a second person holds the projector (and its attached plate) in place, use the security key to secure the assembly

to the appropriate number and letter locations on the left and right sides of the platform, using the four sets of button-

head screws, split washers and flat washers you removed previously. Make sure the screws are tightly secured.

NOTE: Depending on the height of the projected image, further adjustments may be necessary later on. If the image is

too low on the screen (with a gap of 3.5" or greater between the image and the top frame of the cabinet), you may need

to raise the projector to a higher screw location. This adjustment is discussed in detail on page 9 (step 6).

7. Connect the AC power, PC Control and RGB1 IN connectors as shown in the figure below.

8. Plug the power cord back into the power outlet, and turn the projector on.

9. At the front of the 2000i, turn on the computer. Then turn on the projector lamp by pressing the Lamp On button in the

Control Panel.

Aligning the Projected Image

You will need to adjust the projector to obtain a focused image that fits the screen. The most obvious misalignment will be

on the vertical axis: You will notice that the image is about three inches lower than the screen frame. Perform the

procedures that follow to slide the image up to the top of the screen, as well as make other minor image adjustments.

You may also need to adjust for image keystoning. Keystoning occurs when the image is slightly wider at the top or bottom.

Instructions are provided to correct this problem (page 13). However, you may not be able to correct a very subtle

keystoning in the final image. This minor distortion can be overcome by simply enlarging the image so that it extends very

slightly beyond the screen.

NOTE: Before adjusting the image, you’ll need to remove the view port cover (attached with hook-and-loop fastener strips)

to view the image from the rear.

Grasp the view port cover in the middle of each short edge, and pull it away from the cabinet.

1. Move to the front of the unit and crouch down, facing the screen.

2. Look underneath the pen tray and locate the Electronics Tray. Locate a large access hole covered with a plastic cap on

the right side of the Electronics Tray.

3. Remove the plastic cap that covers the access hole. If the cap seems tight, carefully pry it off with a screwdriver,

inserting the screwdriver into the small opening at the top of the cap.

4. Using the supplied 7/16" nut driver, adjust the bolt inside the access hole until approximately three threads of the bolt

(or .25") protrude beyond the nut. As it may be difficult to actually see the threads, you may need to reach inside the

access hole and feel the threads behind the nut with your fingers.

NOTE: This adjusts the angle of the small mirror so that it’s optimally aligned with the large rear mirror. This is the best

starting point for further small-mirror adjustments.

5. Move to the rear of the cabinet, and use the security key to loosen the three button head screws that secure the

projector to the projector plate.

6. Slide the projector as far forward (towards the screen) as possible and then tighten the screws you just loosened.

The top of the screen image should be approximately 3–3.5" from the upper frame. If the gap at the top of the screen is

less than 3.5", proceed directly to step 7.

CAUTION Do not turn the small-mirror adjustment bolt more than three full clockwise turns. Turning the bolt too far

clockwise may crush the spring that is an essential part of the adjustment mechanism.

If the gap at the top of the screen is greater than 3.5", you must raise the projector plate to reduce the gap to 3.5" or

less before you can proceed to step 7. Reduce the gap as follows:

a. While a second person supports the projector, use the security key to loosen and then remove the four button-head

screws (together with the accompanying flat and split washers) that hold the projector/projector plate assembly to

the two sides of the projector platform.

b. Raise the projector plate upwards, incrementing both letter and number screw locations (for example, raise the

plate from I-9 to H-8).

c. Replace and secure the fastening hardware with the security key.

7. Move to the front of the cabinet, and use the supplied 7/16" nut driver to turn the bolt inside the Electronics Tray access

hole counterclockwise, adjusting the angle of the small mirror. This raises the image to meet the upper frame of the

cabinet.

IMPORTANT Before you begin, note that each vertically upwards increment of the projector plate (from I-9 to H-8, for

example) will only raise the image on the screen slightly less than 1/8" (due to the angle of the plate).

Take this into account when you’re determining the position to which you want to raise the plate. Raising

the plate from I-9 to G-7, for example, would raise the image by 1/4".

NOTE: Two or three turns should be enough to raise the image and close the three inch gap. Ensure that at least one

thread of the bolt protrudes through the nut. It may be difficult to actually see these threads, so you may need to reach

inside the access hole and feel the threads with your fingers.

8. Enlarge the image to fill the screen as follows:

a. Using the security key, loosen the three screws (and washers) that secure the projector to the projector plate.

b. Move the projector backwards (away from the screen) until the image enlarges enough to fill the screen.

c. Tighten the screws and washers you previously loosened.
