YS-D1 flash tube/electronics damage - repair/recovery? in Lights, Strobes, and Lighting Technique Posted January 30 Have had a set of YS-D1's since forever, one of them seems busted and wondering what I can do. A year ago this particular strobe would work sporadically (fine testing pre dive but sporadic at depth during the dive) so I thought it was a faulty optical cable, but I replaced cables and it worked fine for a bit but after a few more dives recently it now only goes into red/green alternate blinking mode with full batteries. Also upon closer inspection, though the battery compartment seems fine with no flooding issues at all, I noticed some water lines on the side around the front of the flash tube, even though there are no noticeable cracks, just wear and tear. Any suggestions as to how to possibly salvage this strobe? Most recovery techniques I'm familiar with are for battery compartment related floods but in this case I am wondering if there is anything I can do. I do not dive or shoot as much as before so not rushing out to upgrade strobes yet - even brought out old inon Z220s and tested them but loved the D1's for a long time so wondering what options there are.
