LED Matrix glitchy pixels and it stays on after unplugging

sonofcy · August 17, 2025, 12:28am

The datasheet of the Matrix is needed.
What is the device labelled HUB75?
If connecting the Gnd causes the panel to not work that might be a big clue.
Good luck. I doubt I can help further given what is known.
