Replacement
The Vision 140/150 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 VHD Controller Installation menu (available by selecting Service -> Display Device ->
Configure -> Installation, in sequence).
For lamp or filter replacement, please contact your nearest Vidikron authorized service
center or Vidikron 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 two rear Lamp Cover screws (see Figure 5-1) and remove the cover.
