    I use a MP776 for a club, when I connect to computer, lamp REED light comes on, power light flashes Orange and the Projector lamp goes off, lamp meter say about 220 hours. Any ideas? There are white dots down right hand side and bottom RH corner of display, believe that is a faulty chip.

      Hi Stephen,
      It sounds like your projector lamp is finished. I would try replacing the lamp first and see if that takes care of the problem including the white dots. Keep track of the dots and if they keep growing across the screen that may be your color ballast. Hope this helps.
      Regards,
