Question about returning a couple deactivated C41-500s. Our tenant has moved out, leaving us two C41-500 clients to return once we call up and deactivate them. While gathering them up, I noticed that one of them was missing the power brick that provides wall electricity to the client, while the second one still had the brick there as expected. Is DirecTV going to charge me for the missing power brick when I return these? Or is there some kind of alternative setup that may have been in place at install time like power-over-coax or over HDMI input that I've forgotten about, and so never had a second power brick? Trying to decide if I ought to buy a replacement power brick from ebay or something for $10 to avoid an unreturned equipment fee for the missing power supply. Thanks!
