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?

Since you say it continues to work fine with other IR devices, I would suggest changing that code. Something about that MX-200 might be causing it to mess up the timing just enough so that it doesn't work. So, if you're using a database code, try learning it. Or vice versa. When learning, if capturing from the OEM remote doesn't work, try capturing it from another learning remote and so forth. Might make a difference.

The remote worked for over a year. At the top of my projector screen is an IR "Eye" that transmits the IR back to all other components except for the projector. The IR gets to the projector by bouncing off the screen. Thus double the distance.

This is why I was wondering if emitters get weak.

Well, I programmed another mx-200 (using the same editor file) and it worked from June 7th until 2 days ago. Something is definitely going on. I don't have any trouble with my mx-850.

Well, I believe I solved the issue. Apparently I have a batch of bad batteries. Even though they are "good through" several years from now, it seems the first set got low enough and thus too weak to provide full brightness in the old remote.

When I programmed a new 200, I just got 2 more batteries from the batch. They worked for about 19 days. I bought a new package and the new remote is now working correctly - although its been only 4 days. Haven't gone back to try the old one with new batteries yet but will.

Thanks!!

Heh... Duracells, perhaps?

For years I've had an issue with Duracell AAA batteries lasting only a few weeks in URC remotes. I test them after this, and 3 batteries will be okay, but one will be completely dead. As I discovered, a certain percentage come dead right out the package. The high voltage of the 3 fresh batteries is enough to compensate and sustain the remote for a few weeks, but it doesn't take much usage for them to fall below the minimum threshold.

How did you guess? :).
