On the Rx it sounds like a bad remote lead or just a failed remote.
Do all 3 do fastblink when you initiate a bind? And then one remote stays dark and the other 2 are solid? Unplug the cable where it meets the remote on both and swap them.Does the failure follow the remote or the cable/port?
It definitely needs all 3 in fastblink before you go any farther.All 3 must be solid orange before it will connect and you get servo movement.Logically swap stuff around and try to find the failure source.Try swapping to the port on the Rx that isnt being used.It will take 3 remotes but only needs 2 to function.
