I called Marantz about this very topic and was advised ...................
1.) The DMD engines are supplied by T.I (which we all know)
2.) There is a spec for allowable stuck mirrors, but the marketing guy said he did not know what it was off the top of his head.
3.) He claims that every DLP projector supplier suffers from the problem, which makes sense, since they use the same supplier
4.) He said the problem was rarely noticeable and if present, most likely to be seen when calibrating test patterns.
5.) He also said that Marantz does it's best to screen this problem from end-users - I suppose by returning the worst DMD's.
6.) Finally. he said that if a customer had a stuck mirror in the center of field of view that was visible and objectionable, they "would make it right" - replace it??
I know this is not very comforting, at least for me, but I have to assume that it is not a major problem, or it would be getting a lot more press on these forums.
|Stuck mirrors, dead pixels, or stuck panels. You will run into a associated problem with almost any chip based device. DLP, LCD, LCOS etc.......|
|Let's get back on topic.|
|My personal standard for stuck/dead pixels or mirrrors is this simple: A total of ZERO is acceptable.|
