I have an mx200 that worked correctly until about a week ago. I have changed the batteries and also re-uploaded the mx programming.

It turns everything on except for the projector. I have an IR eye above the screen that "sees" the IR and passes it to the receiver, DVR and Blu-ray. This all works. The projector is supposed to see the IR bounced from the screen. Another MX200 works even with the same batteries. And this one did until a week ago.

I have checked the IR emitters on the mx200 (2 emitters) and they do light up (as seen through a digital camera). However, I can't tell if the intensity is as bright as on the Mx200 that works.

Do IR emitters get weak? Is there a way to fix this one?
