Many thanks to Mr. Laverty and the other contributors. I followed this guide to install a new power supply in my darkened 27” Thunderbolt Display to bring it back from the dead. While the instructions were specifically for replacing the fan, I found that after following them to remove the LCD panel, it was easy to replace the power supply as well. For anyone else who may suspect a failed power supply (loud buzzing and then black), I ordered mine directly from China, supposedly a brand new one. It looks identical to the original in every way and does have a 2018 sticker affixed to it. It took a month to arrive but did the trick. I paid $70.50 for it from wwon_one off eBay. Thanks again for the extremely helpful guide!
