Runco 1080p Maintenance and Troubleshooting, Lamp and Filter Replacement, 2. Unlocking the Lamp

5. Maintenance and Troubleshooting

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.
