Question about Optoma EzPro 739 Multimedia Projector
I had the same problem, and the solution is very simple,. When you remove the cover ( 2 screws) to replace the lamp, then there will be a piece on this cover a bit stiking out. this piece is made to push a small metallic piece to make contact, and then to let electricity pass. so if you try to put a screw driver in this hall, you will feel that there is a contact and then your beamer will go on.
so this security contact is nor operating properly and you need to push it permanently so it will work. I hope my you can understand my english
