    Are all the cables plugged in? Did you try substituting cables one at a time?
    The light source burned out, or the power supply took a dump.
  2. Longshot here, but you may need to initialize it. Normally it's Menu, 2 4 7 0 Enter on the remote. I am unsure if your model can have its software restarted that way as I have never serviced one of that age.
  3. Now that I think of it, the voltage tripler on that model tends to crap out also.
