Trellis lights not on

by crazytechkid on Sat May 02, 2020 1:30 am

so i dont know if this is the right place but i have a neotrellis m4 and some of the lights are not turning on there are six lights placed on the board that dont turn on and there are 2 more that are very dim. I dont know if i have a bad board or some code is messed up (i am using the keyboard code)

I have had this for some time but it has just been sitting in a box so it hasnt been dropped or kicked.

so if anyone could help that would be greatly appreciated

Have you tried some of the simple examples? Such as the toggle code on https://learn.adafruit.com/adafruit-neotrellis-m4/trellis-m4-circuitpython-demo.

I did that and it still has a few lights that are out. I think it may be a hardware issue but I don't know what could have caused it

Are there specific LEDs that consistently do not light? If so, carefully example the area of the PCB around those LEDs. Does anything look amiss? Burn marks? Missing parts? Shorts?
