Hi all,

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:

  1. 13H (I held for 5 seconds), and
  2. 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?

Thanks for reading!

    3 month no charge repair, then repair at cost up to 12 months, per this:

    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.

      I pulled a driver in a first-generation D4. It wasn’t too bad. The new ones would be more work because they have aux LEDs.
