Lamp Replacement
The lamp should be replaced when it reaches the end of its life (typically 2000 hours), or
sooner if a noticeable degradation in brightness occurs. Contact your Vidikron dealer to
obtain a replacement lamp.
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.
Using a Phillips screwdriver, loosen the two
Lamp Cover screws on the side of the
projector and remove the cover.
3.
Remove the three Phillips round-head lamp assembly mounting screws. These are
identified by arrows pointing to them on the lamp housing.
4.
Grasp the lamp assembly handle and pull gently, removing the lamp module from the
projector housing.
5.
Install the new lamp module. Secure it in place with the three screws that you removed
in Step 3.
6.
Replace the lamp cover and re-tighten the two Lamp Cover screws.
7.
Re-connect the AC power cord to the projector.
8.
Reset the Lamp Hour counter. To do this, press and hold the ENTER, DOWN and RIGHT
buttons on the projector rear-panel keypad (see Figure 2-6) simultaneously. Then, press
the ON button. When you do, “LAMP 0000H” appears on-screen to confirm the counter
reset.

Maintenance and Troubleshooting
Always reset the Lamp Hour counter when you replace the lamp. Do this
only if you have just installed a new lamp. This will ensure that number of
hours logged on the lamp is accurate.
