Stop programming remotes while 'on the job'. Maybe it was sensitive to your technique and closed its eyes so it didnt have to watch.
'On the job' means the same thing everywhere, right?

Had the same thing happen here at one house with 3 t3v's and rp1's. It happened to 2 of them after updating them within 20 minutes of each other. Don't know what it means but I shut the switch off then back on and they have worked since.

Turn off the ambient light sensor in the software. I had the same problem with my personal T3V and a few clients. That solved the problem each time. It is now the first thing I do.

Another important thing with a T3V is to check the size of the file. If it is too large or even approaching full it will cause a myriad of issues.
