Hello ;

I am using 40x2 vfd vacuum tube lcd on one device. But it is no longer produced and I cannot find it.
Codes: M402SD10A and M402SD62A

I want to use the normal 40x2 lcd instead. The pins are exactly the same, but I can't get an image.

Anyone have an idea about this?

Did you try adjusting the contrast?
