First of all, I love this product; it’s going to help with reminding me to keep my plants alive :)
I do have an issue with the back-light though, as in when I call display.set_backlight(0) it does nothing. So far I’ve created a small python script to mimic the behavior of toggling the back-light and that also doesn’t turn off the back-light. I’ve tested the pin with a simple LED circuit, and it works, I’ve also traced all the wiring as far as the connector for the display.
I do have a video showing that the pin is being toggled between 0 and 3.3 volts, but with no change on the back-light. I’ve attached a picture of the solder joints (though I’m confident it isn’t that)

I’m at a loss to be fair, the Pi Zero is on latest firmware and code, the Pi Zero works with my enviro+ pHat; I’m just not sure where to go from here.
