It worked fine for over a year, and then one day it simply won't turn on. Absolutely no response from pushing or holding the power button. I checked the plug at the printer and there is power coming out of the cord. I carefully opened the printer up but I don't see anything that looks like a fuse or breaker. Replacement / alternate printer plugged into same outlet works fine.

@murraymckee if anything it will be inside the power supply. The open on your printer is encased in plastic housing. You would need to remove the power supply, then disassembly the plastic casing. Once you have that accomplished, post some well focused pictures of what you see with your Question. That way we can see what you see and hopefully identify any faults on the board. It should be enough to remove the side panel and then the power supply.
Remove the screws shown in the image to remove the power supply.
Just in case you need it, here is the Epson ET 15000 L14150 Series Service Manual and check this video around the 2:40min mark to see the location oof the PSU on your printer.

It's sealed on the Epson machines. Best bet is to find a ground and test with a DMM to see if any of the lines are low. It's probably only a few voltages. If I had to guess (partially because if I was going to buy an Epson like this I'd get the 8550) it's 5V and 12V lines, 3.3V rails might be present but it will be a very small amount of them - one line at most for standby.
Hopefully Epson has standardized on the parts they use in the ET- series, so it will be relatively easy. Or at least they standardize by platen type to a degree such that one supply will work in a 6 color 8550 and the 15000.
@nick you know that everything is always sealed since the profit before planet/people machinery does not want us to fix things. It's a plastic case put together by people, it can be disassembled (cracked) by people. Sure, one could just go ahead and replace the PSU from the get go, but that also defeats the purpose of eliminating eWaste. Live a little, crack the beast open.
@oldturkey03 But seeing as humans built it that's why I'm hoping for platen standardization with the printhead being the difference between the many CMYK EcoTanks vs the photo grade ones. The difference I use to mark them is the color range - CMYK being document, photo being 5+ colors (at a minimum, CMYK+PK).
