SV06 Plus - assembled and powererd but LCD is dar

Hey, got the SV06 plus delivered yesterday, just did the assembly, and powered on but the, got a red light on the extruder, and there is a blue glow from inside the control box. But the LCD is dark, no backlight, no image, no nothing. The plug is in… any suggestions on what to check?


Never mind, opened the control box and found the LCD cable was unpluged.
