NEC MT1050 pojector

I had the same issue and it was very frustrating....I found this projector in the trash and I am assuming that the original owners got frustrated and threw this out, but I read up on the switches that control the cover placement and it is amazing I just got done watching my honeymoon video on the wall of my home. One mans trash is another mans treasure. Thank you for posting to this site so that I knew where to start. Make sure those little switches are fully pressed down (there is a switch under both filter covers as well as the lamp changing cover) I am an idiot when it comes to this stuff, but I figure it out.

You are right about the filters. It turned out that the projector was slightly damaged and there was a filter trigger that was not being pushed in and was not allowing my projector to turn on. Had to have that disconnected by a professional so that the projector would work.

I believe this indicates a lamp failure. Make sure the lamp is seated correctly. If you haven't checked, take the lamp out and look at it. I left off a connector (the yellow wire I think) once when reassembling an mt1050 and had what I believe was the same indications. If you have taken the projector apart double check that all the wires are reconnected. Other than that I'm not sure.
