Bought a 73842 five months ago. About a month into it, I had a large halo on the left side of the screen. I called Mits and they sent a tech out who attempted to replace the light engine. The "new" light engine was bad and I had to wait 2 weeks before the tech could come out again to put in another light engine. After putting in the second light engine, all was good except the image had a noticeable tilt ...about an inch or so in the clockwise direction.
Called Mits to complain and they said this is as good as it gets and that it will never be perfect. I told them it wasn't like this when I bought it, so I would think the picture could be fixed to be level and straight. I asked them to send out another tech and they said I would have to pay for the service. Unbelievable. I even emailed them pics and they said there is nothing wrong.
Well I decided to pay another tech $125 to fix the crooked image. He was here for two hours and after fooling around with the DMD board? He was able to get it straight. He did tell me that he shouldn't have had to move the board and also said it should not be touched.
In any event the picture is no longer crooked but now I have noticed the picture is incredibly dim. Its almost unwatchable and even in a dark room, I'm finding it hard to watch without straining my eyes to make out anything during darker scenes. Brighter scenes the picture looks white washed. Colors look washed out and I don't have the color depth. Another way to describe this is foggy or a haze over the entire image.
I called Mits and they said probably the lamp. I only have 900 hours on it. They sent me a new lamp over night and I put it in. No difference.
Is the light engine going bad again? I'm losing patience with all of this. Very frustrating.
