The lower 4 segments on the GB wand kit don’t light up. When I adjust the pot, they all light up ok so I know the LEDs work. The whole display is shifted up though. Is there a way to recalibrate the bargraph?

Every time I’ve had this issue, it’s from the ribbon cable, specifically the ends that are silver not making contact with the board or the bar graph. They sell these cables on Amazon. I’ll give you the link just let me find it. You can grab them in a pack of 10 for almost nothing and if that doesn’t solve it, then you may have bigger problems, but I would start there, especially if you’ve been unplugging it and plugging it back at multiple times.

This happened to me when I was initially testing my electronics setup. Turns out I had the ribbon plugged in backwards on the main board. Flipped it over and everything has been fine since.

Looks like the ribbon cable is either damaged, not seated correctly, or backwards. After being an idiot and put a screw through mine (long story), I bought these:

Sure, it's a 10 pack, but at least you're covered for the future!
