happy but frustrated
I finished this morning to assemble Original Prusa i3 MK2 .
But when I clicked power on button ... nothing happened ! I retried two or three times and seemed to have no power at all . I clicked the LCD-knob and all I get is a beep ( short and severely followed by long and sharp ).
I checked 3-4 times electonic assembly and I have no idea where is the problem! 😕 Please, I need help!!
Re: happy but frustrated
Does the LED for the power supply at least come on? You do have the proper AC voltage selected?

Best guess is that you have the LCD cables on the RAMBo the wrong way round. Ensure that the location lugs are pointing inwards towards the centre of the board; post a picture if you are unsure.
