My Black Box B40-C stopped recording in April 2018 and I just noticed. It does power on. Is there any troubleshooting guide or firmware update? My guess is that "Black Box" isn't a brand, it's just a way of saying that it's generic. Here's a link to the one I purchased. https://www.amazon.com/gp/B00TXR2P40
