My Optoma GT1080 (Short-Throw, 3D) is flickering blue and red one the screen while watching.?

It's as if I'm watching it normally, but it's showing 3D colors, and then back to normal colors, rapidly.

Check all cables and connections first, and if none of them seem to be the cause, it will need professional service. Contact Optoma and ask where to send it.
