Could be . I just know that after I dropped my dry side it never worked again and did the same as yours. I took it apart to try and figure it out and watched the piece not connect or work insink. Being the magnetic drivers inside.They want me to send it in for a tech to look at. I don't know if there is necessarily anything wrong with either the dry side or the driver. The guy I got the older replacement dry sides from said they worked fine. I actually bought two from him and both do the same thing with the driver. It's so weird. I wonder if the dry sides are just too old maybe?
