I have 2 18-80 cinema lenses that suddenly stopped communicating with a 1DX Mark II. No AF servo or anything else. All my other lenses work just fine. Suggestions?

If this is a case of the lenses working prior and now they're not, I would first check their performance on another camera body. The power cable you are referencing is for connecting power to the servo zoom and zoom rocker on compatible Cinema EOS cameras.
