My mid 2017 27” iMac died on its own

An Apple support chat later and I determined that my mid 2017 27” iMac has mysteriously kicked the bucket. I tried all of their troubleshooting including resetting the SMC and trying different cables and plugging it to different power circuits in my house. I’m putting this up for myself and to see if anyone out there has had this similar problem or hopefully has advice.

I bought this iMac to replace my perfectly working 2012 model. The 2012 iMac was used heavily even survived a house move and it never had a hiccup. I have a Genius Bar appointment setup for next Saturday but I’m dreading getting that out of warranty repair estimate. If anyone has any advice on what else I can try, please feel free to share.

Plain nothing... No warming up sounds or anything.
Ouch. Could be a power supply or logic board. However... I have been able to fix this exact problem on a few imacs by re-seating all the cables. But that involves opening it and re-applying adhesive for the screen of coarse.

Also, just to cover some silly basics
1 - Is it plugged in to the wall? (Ive done that...)
2 - Have you tried that outlet with something else you know works?

Did you ever change out the RAM, or add to the factory-installed RAM?
If so, have you tried removing the 3rd-party RAM, and using ONLY Apple factory RAM?
Just askin' ...
