James,
I am having the same issue, I hope you get it resolved. I have had mine installed for almost a year and it appears that now for some reason or another it is not getting enough power. I took it down yesterday and charged it. There is a hidden mico usb port on the left side, it hasn’t seemed to remedy my issue though as one day later I am back in the same situation where it refuses to connect. Mine is now reading 3557 mV in the reported voltage.
Thank you,
Cameron
