Hi all - i recently had a blown board and replaced it and flashed to sailfish - when the printer starts the little tune plays and i can print through USB with simplify3d with no problems, when the print finishes the little tunes play at the end.

My issue is that the LCD will light up but there is nothing on the display - it is obviously working fine and the firmware is installed but there is nothing on the LCD. I tried another lcd incase the first was blown but that does the same, justpowers up and the backlight is on but no menu etc.

Any ideas?
