From the very first boot-up of my new 64x32 RGB LED Matrix, there have been extraneous LEDs lighting up in large horizontal swaths. The bands seem to move slightly with the animations and don't appear to be static pixels that are malfunctioning. They generally appear to be concentrated near the middle of the left side of the matrix.
I have tried three different power sources and the problem is the same for all three:
- USB 3.2 Gen2 Type-C PC port
- USB Type-C 20W wall fast charger
- USB Type-C 25W wall superfast charger
The very first demo routine (red sand) has artifacts that make many of the scrolling animated characters unreadable. When loading up a DC Metro routine (
https://github.com/metro-sign/dc-metro) there is a significant amount of noise while loading, but then a seemingly random amount of noise when displaying the actual cars and times. I have also tried the "Halloween eyes" demo and have similar issues. I have linked two videos and embedded several pictures below to help diagnose the problem. Any and all help would be appreciated.
