I use my Ronin RS2 with the Tilta Advanced Ringgrip. This used to work perfectly but recently the Receiver Module won't turn on anymore. I've tried another Receiver Module but it won't turn on as well so I assume the problem is in the RSA/Nato port. Has anyone experienced problems with this as well and is there an easy fix?
