Possible dead pixel on a 60 ring LED segment

by huntrontrakkr on Wed Sep 09, 2020 10:27 pm

Hi all,

Just received 4 1/4 sized 60 LED RGBW Neopixel rings. On one of the segments on the midway point it appears that there is a dead pixel. nothing will light up beyond it. Confirmed with a multi-meter that power is getting all the way through, just data is not clocking pass the dead pixel. Received this yesterday and would like to get a replacement part if possible

Sounds like the a back solder joint on a Din or Dout pin. Can you post a clear close up of the last pixel that lights and the first one that doesn't?

Hmm. Nothing really jumps out from the photo. Have a close look at all 4 connections on those 2 NeoPixels. If there's a break in the Dout->Din path it would explain your issue. In which case a touch of your soldering iron might fix it and get you up & running asap. If not, we'll get you a replacement.

Gave it a shot, didn't help sadly :(. maybe the pcb was torqued/bent while transporting and broke a trace or something.

It easily could be.

Please email support@adafruit.com with a link to this thread, your order number, and request the replacement of one NeoPixel 1/4 60 Ring - 5050 RGBW (temperature matching the order items).
