We are working on an LG dishwasher that there is power to the main control board but there is no lights on display that work and when you try to push the start button nothing happens. Could there be a shortage from control board to display or could somthing else be causing this? Any suggestions?

Hello
Are you getting proper voltage in to the unit ? Do you have proper polarity with a good ground ? You said you have power to the control board , do you have 115 volts to the main control board ? Normally proper power in the the board with no display is the main PCB. I have uploaded the diagnostic guide steps in the link below, start on page #8 and double check all of the diagnostic steps to verify before replacing the board. Matt Ace technician
