Audio Technica 3000 series body pack locks up, no audio out.

Has anyone ever had an Audio Technica 3000 series body pack transmitter that was working perfect and suddenly "lock up"?
This is a current model version body pack, batteries were good, never had any issues with it all, the receiver still showed RF level, no audio, no battery status. None of buttons on the pack would function and the power light was orange, normally it's green for power and red when in mute, never saw orange before. After popping out the batteries to turn it off powering it back up it was working fine.
Of course it worked fine during dress rehearsal and waited till about 3/4 way through play last night till it locked up.
No problems with the other 17 in use during the play.
These are all mine so I know their usage history.

I had an issue somewhat like that, no audio but still showed battery status. I switched packs on the same actress and it happened again. Switched pack to high power and made sure the antenna didn't contact any skin and it worked.
