I've had my cyan D4K Hanklight for only a few months (ordered in April) and I can't seem to get my main emitters to turn back on? I had the light on while cable managing my PC and all of a sudden it turned off. I didn't touch the switch, it just cut off.I checked the cell first which runs fine in my K1 and was at 60% capacity. I've tried these 2 factory reset methods:
13H (I held for 5 seconds), and
disconnect tail cap, hold switch, reconnect tail cap, release after 4 seconds.
Neither appear to do anything. The auxillary LEDs are still running in low mode, but I can't seem to change them with the usual 7C for mode and 7H for color.
Is there any possibility my dedomed 519A emitters are still alive and kicking? Or should I just order a "domed" normal version?
This definitely sounds like a bad driver, not a failure of the emitters. I don't think there's a warranty as such on these, but I bet Hank will send you a new driver if you can solder.
I have not personally swapped a driver board in these lights, but multiple people have told me it's a big pain. It's one reason I only buy lights with flashing pads, rather than lights that you have to take apart to reflash, if they run Anduril.
