@thermosheater I had the same issue and can confirm it was the press down connector closer to the fan, not the ribbon cable. I put everything back together and had no touchscreen or card reader and started reading all of your comments, fearing the worst. After reading mgrandi's comments above I went back and checked that connector, it seemed seated but was wobbly. The card reader board has a little indent on it's edge, and the press down connector has a little tab. It looks like they should line up, but the press down connector needs to be a bit further toward the side with the card reader slot (away from the center of the switch). It seated more firmly this way and everything immediately worked again.
