The change filter light keeps coming on

The red indicator light usually comes on when something needs attention. Most often it has to do with the lamp timer or the filter timer. The projector keeps track of how long it's been since you've changed the bulb or cleaned the filter(s). You can reset these timers in the menu. Be sure to clean the filter before you reset the timer

unplug projector for about an hour, and then remove bulb, and filter, inspect areas for damage, also inspect it to make sure your inserting it correctly. put filter and bulb back in, put covers back on, then plug it back in. reset the timer. if you still have problems let me know.

You can reset the "Filter Time" on your projector and it will clear this error out of the system.

1) Clean Filter
2) Turn the power on
3) Hit the Menu button
4) Once the menu appears choose "Options"
5) Choose "Filter Time"
7) While the time is displayed hold the "Reset" button on the remote for 3 seconds
8) The "Reset" menu will pop-up and choose reset.

That should take care of it.

Goto Advanced menu and select option then lamp Time hold down the reset button on the unit for 3 seconds until a new screen comes up then hit reset. Do the same for resetting the filter time

several reasons, it could be you havent had its 1000Hrs service and is overheating or filter needs cleaning or lamp is past its change time and is generating too much heat or sensor can sometimes come away and drop into light path causing false sensing of temp.
