Welcome to the SeeMeCNC Community

Have you guys ever seen this happen?
I've been using this reliably since April. Sometime last month, the display went blank except for the upper left where I could still see the Temperatures of the bed and hotend, but last week, something happened, and now I get nothing.

Any suggestions?

Thanks,

Brad

There is a contrast setting on the back of the board. Try that first. If it fails, then you may have a dead board and should contact SeeMeCNC support. If you can't find it let me know and I can post a picture. I had one replaced early on but it has been fine since.

I agree with Noventix by checking the contrast control.
This really sounds like a defective lcd board or cables plugged in wrong.
You have not removed the cables lately have you?
