Dead D4K? (reddthat.com)

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!

I'd email Hank. I doubt all the emitters would fail in the same instant, so this sounds like the driver board or some of its wiring has failed.
