Hello, I don't understand why but yesterday i was unable to shut down my TV. I have changed batteries, still not working When I'm plugging my remote in USB on my mac with the app I can do everything with "test actions" menu, but when i remove the usb cable the remote is not working. Nothing happens when I tap a button (no light, nothing) I've tried to restore default configuration within the app and restore my configuration, still the same. I've done nothing on my remote
