Any Known issues with the v3.5 power board?

[ordnancetech82]

I recently got my v3.5 kit and after assembling it worked and charged fine for about a week. Now when I plug it in, the charging LED will only light up after a couple minutes of being plugged in. I initailly brushed this off as a fluke and allowed it to charge overnight. The next day, the indicator was still red and the system will briefly light up before the screen goes blank as if there is no power at all. This happens both without the charging cable and with it plugged in. I reflashed the image just in case and this made no difference. I then tested power directly to the pi and it boots normally with direct power. Are there any testing tips for my issue or known issues with the boards?
