One Random Green LED

broyuken · Jun 24th 2025

Hi all,

I have a hyperion setup that's been working pretty great, with one small issue. I think it's a fairly new issue, I have a Pi4 with a led strip on it. It's about 260 active leds, the strip itself has probably 300 led's total but the last 40 are disabled. For some reason, led 261 is lit up green, and I can't get it to go out. No matter what it's lit. Even if I turn off all the leds, it's still lit up.

LEDs are set up in WS281X mode

GPIO 18

DMA 10

PWM 0

Anything you can think of to sort this out?

Best regards

The LED may be defective.

pclin I thought green means OK and red defective

But you are totally right. I overlooked the fact that all LEDs after the green one aren't working, so it's most likely defective.
