Hi,

I have seen something simmilar to this in the past.

There are two things that have worked for me.

1. re-add the IR code for that device and perform a Super fast device swap.
2. perform a F/W flash on the blaster.

A little more info would help though as per TouchCommanders post.

Are you sending codes via the remote or a NC-50?
get a digital camera (mobil phones work) and look at the remote or NC-50 through the camera and see if you can see any IR flashing.
