A while back my LCD Shield had an incident in my backpack and the blue contrast adjustment snapped off. I couldn't find it, it must have walked off.
I was set to order a new one.
Ordered a new one from China, but I found the old broken screen and didn't have a replacement part, but I did have resistors. I found
a usable setting:
|Fixed Contrast Replacement|
I guess I'll have a spare once my other one gets in, but I was happy I made this one work again.
