RGB Matrix with Pi 4 B

Post by Cheezheadsrule »

I've used 3 pis, so I don't believe that's the issue. When I plug the display in and run my code, I either get nothing or random colors. I've unplugged, replugged a bunch of times. Is either the display or matrix bad?

Have you used the other pis with the matrix and had it work? Also, have you loaded the new pi with a current version of the software?

I've tried 3 other pis and had same results. Yes I've done all the updates.

If I wiggle the bonnet the display shows different colors but still all gibberish. Is the bonnet bad?

Can you post pictures of the bonnet from both sides?

Should I just order a replacement? I'm pretty sure it's defective but waiting for a exchange is taking too long at this point.

I was looking for the bottom side to check for soldering defects. Go ahead and contact [email protected] with a link to this thread; they will replace it and decide if they want you to return it.
