    Default Pixel Colors Off

    I have about 10-15 pixels at the end of a string that have colors that are off from the rest of them. It is at the end of 200 pixels. It has power injection at the end. I checked and I have 12.14 volts. I swapped out the 50 pixel string and that doesnít change it. It also displays white properly. The very last pixel is always red too. Here are some pics I took the other night.

    Are you using FPP? Sounds like an output channel problem. Does it work when you test the lights from the hardware side?

    In test mode the green is yellow. Red & Blue are ok. Channel Config data looks right.

    Try changing your start Chanel in test. If 1 use 2 then 3. If it makes it RGB, then look at your input and/or output channel setting. Could be a bad WS2811 chip in your first yellow pixel

    Havenít had a chance, cold and snowy, to check anything. If it turns out it is a WS2811 chip. Do I replace just the one pixel before the miscolored one or it and the one that is miscolored?

    Because it could be either one that's bad and there's no easy way to tell which, most of us just replace both to save time.

    Thanks thatís what I thought. I have always done that when a string stops lighting from a pixel to the end.

    You said in the beginning that you changed out the pixels and the problem persisted. If the lights show up wrong on two different strings wouldnít that mean itís a configuration issue?

    It's possible the LED itself isn't soldered in the same order, see that in the automotive stuff all the time, RGB on one and GRB on the next and wire colors usually mean zero cause I've seen red grounds, yellow to blue LEDs, nothing would surprise me so don't assume anything and test everything. If the pixel will change color at all then it's probably a channel order problem with that pixel.
