Hello Douglas,

I have tested the continuity of both my ribbon cables and the both test fine--thanks for the suggestion. I have re-seated the cables multiple times and have tried with and without the GPIO connections

I have tried multiple Raspian OS install each on different 16 GB Micro SD cards. One was even a purchased pre-loaded card all had the latest version (September 2019 and had Update and Upgrade run). I still have the same results.

I appreciate your time and your suggestions, thank you.

It sounds like an incomplete connection. If you aren't too familiar with these little ribbon connectors and their locking mechanisms, read up on how to seat them all properly - they can be a little tricky. You probably installed the ribbons correctly, but it is worth checking because it is the most likely issue and the simplest to fix.

You could also closely inspect the connectors to see if they aren't damaged, or you could even measure continuity of all connections.
