The use case that I have found for a monitor or TV sourcing 5V on an HDMI connector is called MHL (Mobile High-Definition Link). The 5V is used to power/charge the MHL source device (possibly a smartphone or tablet). I think it was a bad idea to reuse the HDMI connector for this other standard. I'll need to check if I have any MHL compatible ports or devices. Maybe there is a case of a standard HDMI port having this capability?

Products sold with no guarantees? Is that legally permitted? I sometimes often don't understand sparkfun. I think they were the company that took a SOIC chip and sold a breakout board for it.. when a through-hole version of the chip was available anyway!

Notice to anyone who may have read this post earlier - I have updated it based on a response to my inquiry on github. You should only modify this design at your own risk. I'll update when I have more info.

Everything on the internet comes with a "Buyer Beware" caveat.
