Also had a small problem with my Optoma projector. And at 2137.00 with a msrp of 5999.00 Optoma had completely exchanged my projector, I do not believe the place I bought was an authorized dealer. But I may be wrong. I remember saying to them, that I could exchange through the company I bought from within 90 days. Or go through you. They only wanted to see a purchase form for the date of purchase. They honored it no problem, and I got another Optoma projector free of all charges. Their response was, as long as it is within 90 days they will give a new exchange, over 90 days they will have to send it to there repair dept... (speaking of Optoma)
