Neopixel RGBW 144 led/m dead white diode

by axj2466 on Sat Jun 03, 2017 4:15 pm

I'm pretty sure that one of the white diodes (is that the right word?) on one of my neopixel strips has died. It may have been dead on arrival, but I'm not sure since I've only been using the red, green, and blue diodes separately to avoid overheating. As can be seen in the other pictures, the three rgb diodes in the led are working fine, just the white one is not. I've got the recommended capacitor hooked up between the strip's power supply input, which is from a 3.7v lipo battery. I'm also using the recommended 470 ohm resistors on the data lines. The strip is currently back to back with another in a tube, for a lightsaber I'm building, but I have it limited to 1/4 maximum power to avoid overheating.

I'm really not sure what to do. Taking the whole thing apart and removing the pixel, then re-soldering would require cutting the blade tube down again and modifying the diffusion material...plus, even with the best light diffusing there would be an obvious gap in the blade where the solder joint is. On top of this, then the blade would be a different size from the other blades.

I'd like to prevent this from happening again if possible. Is there something I may have done wrong that isn't really covered in the recommended readings? Is this worth asking for a refund?

Thanks, any info is appreciated.

When did you purchase the strip?
