I have 2 NP-200 projectors installed in a school which show white dots on a black background and black dots on a white background. This is caused by the DMD chip losing pixels. Only solution is to replace the chip, I'm researching now if that i an economical solution.
I would be willing to bet the DMD chip is failing the cheapest used one i seen was on e-bay the chip # will be something like 1076-6319W the only part of the # that matters is the last from what i have seen they tell me the 6318W and 6319W is suppose to be the same chip the used on i seen on e-bay was $124.00 probably better off seeking a new projector if you can not replace yourself as you will have over half of the cost involved hope this helps Robert
Jacob, what element on the mainboard is the source of these dots? I have the same problem - it is only one dot now, but I think there will be more with time. Also, the second question is: how do I unscrew the mainboard from benq W600+? I remoced the metal cover, unplugged all the cables, but there's something still not letting the board go.
