Regarding about the damaged pins of ISC sockets returned at the FIXTURE ROOM, we noticed that all of these returned with damaged ISC pins occurred at the bottom of the pins. Every time returned to us we took picture before we clean & changed pins. We make sure we give to HW the ISC sockets without the damaged pins. We had no idea how this happened but we will endorse this matter to night shift and give you feedback also. Next time this problem occurs again we will make sure to inform you & our Fixture HW.
