I’ve just gotten WLED setup for the first time. I’m using one WS2812B RGB (30 pixels/meter), ESP8266/NodeMCU, and 5v/60W power supply, and WLED_0.10.2_ESP8266.bin. I’m having an issue where I have a persistent red, green, and blue pixel. See screenshot, I’m trying to display solid white but even in the peek there are those 3 colored pixels. Can anyone help? What am I doing wrong?
Have you setup any segments? Only thing that pops into my mind.
I had some weird things going on with one of my WLED installations. In my case, the first half the pixels were dark except for a few random pixels. In my case it happened when I accidentally hit sync. Thing is, I couldn’t get back to normal. I tried deleting and recreating segments, rebooting and power-cycling, but they didn’t make any difference. What finally fixed things was factory resetting the EEPROM in the Security and Update settings.
While reading along with the weird things, and seeing “accidentally hit sync”, I was about to suggest that very thing you did to fix it.
Hi! Although I can’t find the corresponding thread, another user had this exact problem before.
The solution @easp suggested should solve the problem
If it still happens, you’ll need to install esptool and erase the flash completely using
esptool.py erase_flash and reflash WLED.
