Okay, I plugged it in. I don’t have a switch installed so it’s “on” as soon as the plug goes into the wall. I’ve got lights on the power supply and the light on the board is on but no screen display (LCD). I’ve double checked the orientation of the plugs to the LCD and they seem to match the photo online in left/right/top/bottom/stripe orientation. No fans (likely don’t run until a print is running I assume). All three fuses good.
Where should I start?
