I'm trying to fix a Blinkytape that is only working for the first 4 pixels (pixels 5 and beyond are not lighting up).
I have tried the button reset and reuploading firmware - that gets the first 4 pixels to show the rainbow pattern again, but the others still do nothing. I can also change (using the latest PatternPaint for Mac) the pattern of the first 4 pixels.
Oh, one other interesting thing, when plugging in the strip, most of the time, all the pixels blink on for a moment then go out (occasionally, only a few [plus the first 4] blink).
I'm guessing that there is a problem in the connection between the 4th and 5th pixel, but I'm not sure if there's a reasonable way to go in and fix it (or if it could also be a problem lower down in the chain).
Any suggestions? My first thought is to remove the end-caps, slide the plastic sheath down and try to see if adding some solder along the joint between the 4th and 5th pixels might do something. If that did work, then putting some sort of thin splint between those pixels and pulling the plastic sheath back over.
