Ok I decided to go for a drive and pick the right reisitor. Just soldered in on and this is what happens when I turn up and down the contrast.
No text just 2 lines top and middle.
Iv still got the plastic film on the screen.
Does anybody know of a different download for the mega, ramps and lcd so I can test the screen that way? Just trying to think outside the box
