Can anyone provide the serial number(s) for the cameras they had this experience with? I recently acquired a pre-owned Ultrastar color with a serial number below 050 that has the problem. I have also used the exact same camera that has a serial number above 140 that does not have the problem. Was wondering if earlier cameras exhibited the problem more so than newer ones. And, what was the final outcome with either tweaking the AB potentiometer yourself or having SX repair or replace the camera.
