Sid working---> LCD not working

MIDIbox SID
1

My power supply works-

My Core works- loaded MIOS, and loaded SID OS with no problems.

My SID makes sounds- (noisy though)

My LCD is not happy-

It came with an adjustable resister, do I need to use it? and how does it get wired in?

When I hook the LCD up as it shows in the Schematic,  it is just bright backlight with no characters..

This is the display that I am using-

Most often you can use the LCD schematic from UCApps.de. If it does not function, try using it the other way around (meaning just rotate the cable by 180°). In 80% the LCD should work the one or the other way.

Anyhow, I have no idea about the adjustable resistor. Just try the middle position first and then adjust it if needed.

Greets!
