So I wake up today to one of my G5 radions off. It was flashing red and green. I did a software update and it was saying open circuit? I started multiple times and turned it off and on. I also cleaned the lens and around the fan as I normally do every so often. After about an hour of messing with it finally came back to life for about 5 minutes and I thought it was good. I was wrong and it then blinked a few times and it back to the red and green light on the buttons. Has anyone had this happen before?
