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 have several white dots all over the screen. They're more that pops up as I watch it and the dots never goes away. Does anybody know what I need to do to fix this problem? Thanks..
Phone NEC and get them to swap it over if it is under warranty. They are very good like that and you will have a replacement next day via TNT. Take out the bulb and keep hold of all the cables and remote as they will send you the projector only. Put the faulty one in the box and send it back. TNT will collect it and it is part of the returns policy. No cost involved.
your dlp is is failing and needs to be replaced. it usually starts as one or two and continues to grow sometimes appears as white dots sometimes black dots
The white dots/stars you are seeing is a failing DMD board. It is the board with the million little mirrors on it. The white dots are mirrors stuck in the on position always reflecting the white light from the lamp. The DMD board is a technician replaceable item and part number varies by model code. Please contact a local servicer to have them look at your TV so they can order the right part number for your DMD board. Please take a moment to rate my answer. Thanks....
