This has been a major factor in my continued support of DLP, any clarification would be helpful!
800/639-3010 .... ask for Technical Support or Service department. Ask them what happens if you buy a Panasonic AX100U from them and receive it w/ a dead pixel.
Buy a projector from bob's camera in the Bronx? Yes - the manufacturer is going to tell you that you are out of luck if you have a dead pixed.
Buy a projector from an authorized dealer and no manufacturer that I can think of will leave you hanging with a dead pixel. I can speak with direct experience on Panasonic home theater projectors, Sanyo home theater projectors, Epson home theater projectors and Hitachi home theater projectors.
In print, yes, many will leave an open window just in case. Basically it is my understanding in talking with various service managers with the manufacturers, this is for the "big box" stores who wouldn't be able to handle the returns/exchanges. Assuming your average consumer who buys from "big box" America doesn't know what a dead pixel is anyway.
However - where you listed Optoma for DLP, I'll at least throw out a LCD - Epson.
Check their home cinema lineup. No dead pixels for the lifetime of the warranty.
Hope this helps!
