Lamp and Filter 
Replacement
The VX-44d/-55d uses a Cermax® Xenon lamp to deliver its high brightness. The lamp 
should be replaced when it reaches the end of its life (typically 1000 hours), or sooner if a 
noticeable degradation in brightness occurs. When you replace a lamp, you should 
replace the filters as well. 
Keep track of the number of hours the lamp has been in use and be aware of any changes 
to brightness. These indicators will help you effectively maintain operation of the projector. 
To find out how long the currently-installed lamp has been in service, select Lamp Hours 
from the DHD Controller Installation menu (available by selecting Service -> Display 
Device -> Configure -> Installation, in sequence). 
For lamp or filter replacement, please contact your nearest Runco authorized 
service center or Runco dealer. Do not attempt to replace the lamp yourself!
1. Turn off the projector and unplug the power cord. Allow the projector to cool down for 
approximately 45 minutes prior to removing the lamp assembly for replacement.
2. Loosen the four rear Lamp Cover screws (see Figure 5-1) and remove the cover.
Figure 5-1. Removing the Lamp Door
3. Pull (out) and turn the lamp lock lever, which is located to the left of the lamp module, 
a quarter turn counterclockwise to the “unlock” position (
Figure 5-2).

4. Grasp the lamp by its housing only and pull it straight out (lamp slides along guides) 
until it’s free; see 
Figure 5-3. Discard the lamp using safe disposal/recycling practices 
or contact your Runco dealer for a possible re-lamping program. 
Figure 5-3. Removing the Lamp
5. Align the new lamp with the top and bottom guides on the left side of the lamp 
compartment; see 
Figure 5-4. Slide the lamp all the way in. A slightly harder push may 
be required right at the end to make sure it is fully seated into the terminal block. 
NOTE: The projector will not power up again if the lamp is not fully connected to the 
terminal block. 
Figure 5-4. Installing A New Lamp
6. Pull (out) and turn the lamp lock lever (turned up in Step 3) a quarter turn clockwise to 
“lock” the lamp in place. NOTE: If you can’t turn the lamp lock into position, the lamp 
may not be fully inserted. In this case, partially remove the lamp and try pushing it 
back in again. Then, try switching the lock lever to the “lock” position. 
7. Replace the lamp door and tighten the four screws to secure it. 
8. Re-attach the power cord to the projector and power it up. 
9. Press MENU on the projector remote control (Figure 3-16) or rear-panel keypad 
(Figure 2-3). 
10. Select Lamp Adjust from the Main Menu. 
11. Select Change Lamp from the Lamp menu. 
12. Enter the serial number in the Lamp S/N text box using the remote numeric keypad.

13. Press ENTER to accept the change. This adds the new lamp serial number to the 
Lamp History menu and resets the Lamp Hours timer to “0.” Lamp Mode and Lamp 
Limit remain as they were for the previous lamp and can be changed at any time.

Filter ReplacementWhenever you replace the lamp – or more often if the projector is installed in an extremely 
dusty environment – you should also replace the two filters located at the front and right 
side of the projector.
1. Loosen the six screws holding right side filter access 
panel in place. Then, remove the panel.
 
 
 
 
 
2. Loosen the two screws holding front filter access 
panel in place. Then, remove the panel. 
3. Pull the filters out of the projector and discard. Do 
not reuse filters.
4. Insert the new filters with the wired side in.
5. Replace the filter access panels and tighten the 
screws to secure them.
Always record the serial number of a new lamp. Do this only if you 
have just installed a new lamp. This will ensure that the lamp timer 
is not reset on an old lamp and that the number of hours logged on 
the lamp is accurate.

Lens Replacement
If you need to remove the lens – either to replace it or to prepare the projector for 
shipment – proceed as follows: 
1. Power down the projector and wait five minutes to allow the lamp to cool. 
2. Remove the secondary anamorphic lens, if present. 
3. Place the lens cap on the installed lens to protect it from damage. 
4. Press and hold the “lens release” button located in the top right corner of the lens 
panel.
5. Grasping the lens barrel, turn it in a counter-clockwise direction until it stops. Then, 
pull it forward to remove it (disconnects from the connector assembly).

Error CodesIf the status code display on the back of the projector shows one of the following values, 
you have encountered a likely system error requiring the attention of a qualified service 
technician. Acknowledge and clear the error by pressing EXIT twice on the rear-panel 
keypad. Try resetting the projector by powering it off, allowing it to cool and powering it on 
again. Refer to
