Sudden problem with Phonak hearing aids - can anyone help please?

do both hearing aids have this problem or one only? I had problems with the left HA, they exchanged the cable for the microphone - transmitter, this worked.

My problem caused by the left aid, as mentioned earlier in this thread. Right is working okay.

Good to know cables can be exchanged. But the problem with my aid is not the cable, it’s the switch and/or internal electronics. My faulty left aid has to be sent to Phonak for repair/replacement.
