Good afternoon there.
We have got Smart UX60 projectors in all of our classrooms other than one or two. They have worked very solidly for years since we had them installed in 2011.
Recently the output on almost all of them has become very dim. Before you ask, here is what we have done:

  • Replaced lamps on all projectors (hours are <1000 on all of them)
  • Had each projector professionally serviced and cleaned
  • Reset menu settings such that they are back to factory default
  • Ensured all vents and air intake areas are clear of obstructions


I was really hoping the bulb replacement would have helped, but it seems not.

Can anyone else think of something we might try?
All of the projectors are out of warranty now, so I can't get in touch with Steljes.
