Question about Optoma EP716 Multimedia Projector
From your post, I gather that you know your way around electronics. So, why don't you use a VOM (Volt Ohm Meter) to trace power starting at the PS and see where you lose it. You may find a blown fuse along the way as you didn't mention fuse status (and that projector surely has one). If you do have access to a meter you could also check the ballast to see if it's putting out enough voltage for the lamp. But since you stat that it doesn't power up at all, I would lean towards the Power Supply (PS) and locating the fuse (could be an AGC, etc... or a printed circuit fuse soldered in circuit right on the component side of the board near the edge where power comes in).
Keep us posted, and Good Luck.
