Devo 10 : problem with pot aux 2 and shutdown

Hi,
I have a devo 10 with nrf24l01 and a7105.
When those two modules are plugged in, and aux2 (the pot) is at more than 80%, the radio go off (screen go off).
To get it on, i have two to lower the pot, and restart the radio with main switch.
When the aux2 pot is between 50% and 80%, the rudder stick (in transmitter monitor) is moving when i move the aileron stick.
I try to swap the pots, and with only one pot plugged in, i have the same behaviour only with aux2 (if aux2 is plugged into aux4 port, radio go off, if aux4 pot is plugged in aux2 port it works)
So i think it is a hardware failure of the pot aux2; I try to solder a 28ohm resistor in serial on yellow line, but it doesn't solve the problem (the pots seems to go from 10ohm to 5kohm)
I think it works (don't remember) if i unplugged the modules (nrf24l01 and a7105)
Any thoughts ?
