The probe has been placed in the office and connected via landline. Original flash were dead after a year or so, I had it running with a new one, and now trying a 3rd. But you made a point. Can a probable unobserved hit damage a working probe badly? (probe has no scratch as evidence if such a hit though) or was it an overlooked electrical shock? Finally the main question is whether that probe is beyond repair? Regards, M. Wilfried Gödert wrote: I also have Problems because I am on the way with the boat international.
