Questions about this item

How do I install the 28-631 lamp module and what step is often missed?

Power off the projector and let it cool completely. Remove the lamp cover screw, pull out the old module by its handle, insert the new 28-631 unit until it clicks, replace the cover, then reset the lamp timer in the menu — skipping this reset is the common error.

What maintenance or replacement will the 28-631 lamp need later?

The lamp itself is the consumable; when brightness drops or the replacement indicator appears, purchase a new 28-631 module. Periodically vacuum the projector's air filters to prevent overheating that shortens lamp life.
