My LCD projector won't power up

Don't panic!If an LCD projector won't power up, don't panic. There is a very simple solution on many projectors, particularly if you recently cleaned your dust filter. Check the filter door(s) to be sure they are closed completely. (Sometimes they just pop loose.) Most projectors have a safety switch associated with these doors which prevents the unit from operating unless the door is properly secured.
