Many white dotd appearing on the screen of my w600 projector. the dots are increesing . there are more then 2 hundreed now!
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.

Hi schmidtkm
All the sympoms mentioned above is that of a faulty Mainboard that will have to be either repaired or replaced.
Trust me on this one , I work on Projectors every single day of my life.

You need to check your filters are in place and open up machine an use compressed air can to remove the dust.

omg, I just figured out why OUR projector was doing this! There was an adaptor plugged into it that we use to hook it up to cable to watch games/tv shows sometimes...once I unplugged that from the projector the lines dissapeared!

Hi Martin103
This is a typical BenQ Mp Series problem , and will notice that it will start of intermittently , but later on the white line will appear every single time.
This can only be fixed by replacing the Mainboard of the MP710/720/721
SOURCE: My projector has little white dots that appear on
Take off the front bezel, then remove the screws from the lens,pull the lens out and blow it out with compressed air. Do not touch the mirror or magnifier inside. If this doesn't get all of the blemishes, then you will have to remove the top cover and then the top silver part of the engine and blow it out from the top.
