I bought this LED Matrix panel https://www.adafruit.com/product/2026 (Order No: 3006067-3551398010), and it is not working as it should. There are a few rows (from top: rows 6,7,14 and 21) where the Leds light up when they shouldn´t. When anything on the same column is lit those rows also light up.( see images ) I´ve tried with different example codes, different controllers: Teensy with a SmartLed shield and an Arduino Mega and always the same glitch.
Is there anything I can do to fix the panel? Like fixing the soldering in an oven like people have done with graphics cards. Any suggestions?

How are you making the connection between the matrix panel and the controller boards?

Teensy 4.0 is connected using a SmartLED shield v5, and the ArduinoMega connected using wires.

Re: How to Fix LED Matrix panel?
Direct wiring with jumper wires is very problematic and not supported:

The SmartLED shield should generally be OK though. Are you following this for setup?
https://docs.pixelmatix.com/SmartMatrix/shield-t4.html
Are you running one of the examples from the library?
