I have had my U5 for a few weeks, finally got it running stable after many hours of tinkering. Everything has been good for roughly say 10 days, then the other day, I am sitting here watching and the U5 simply turns itself off. The light goes from blue to red. Then the BT remote is only working sporadically, also very annoying. It has fresh Energizer batteries in it, remote says the batteries are at 88%. Then when the U5 turns off, I have to unplug and plug it back in to fire it back up. The remote no longer works to turn it on, but will turn the TV off and on. The U5 box has plenty of airflow, nothing stacked on it, nothing hot next to it, it sits by itself on a shelf behind the TV, and the TV is a good foot away from the U5, as it is on a swivel mount and turned out and away. I have other BT controlled devices even deeper behind the TV, and they all work fine. Anyone having issues like this?
