OK, I finally managed to navigate +NVIDIA
's rather convoluted support site (it's MUCH harder to start a warranty request than it was last summer) and start the warranty request process. (See https://plus.google.com/u/0/+AndrewDodd/posts/efZofkLYpuo
for the history of this...)
My original email "This is a warranty request for a replacement power supply. The included power supply with the unit has an internal short and immediately trips the breakers in my home
(along with sparking brightly) when plugged in to an active outlet."
"From your email, I understand that you are noticing sparks when you connect the adapter to a power source.
I apologize for any inconvenience caused.
I would like to inform you that the power adapter provider with the Shield Android TV has the cables integrated and we should not be noticing any sparks. However, to isolate the issue and assist you further, please help me with additional information :
1. Have you tried connecting the power adapter to any other power source, to check, if it works fine?
2. Have you tried disconnecting and reconnecting the PIN on the power adapter?
I request you to disconnect the 2 pin connector on the power supply and reconnect it, make sure that its connected firmly and try connecting the adapter to a different power source to check, if it works fine.
Please keep me updated about the status of the issue."
Translation:We understand that our fire hazard of a power supply which should not under any circumstances be drawing more than 500 mA when loaded from a 120v AC line is instantly tripping a 15A
(edit, I wrote 20A but I just checked again, still insanely high) circuit breaker in your home when plugged in with no load connected. Please keep fiddling with that fire hazard until you burn your home down.
The SHIELD power adapter is rated firstname.lastname@example.orgA output, or approximately 40W. Even if it were only 66% efficient - which in and of itself would be a fire hazard by dissipating 20W in a tiny plastic enclosure like the power supply for this thing - it would not consume more than 500 mA from a 120V circuit. Plugging this thing in with no load insta-trips a 15A breaker.
