Start with the 12V supply, because the control panel needs 12V DC even when you're plugged in. Check for 12V at the rear power board, check the fuse on the board, and make sure the connections are clean and tight. If 12V reaches the board but the panel stays dead, the power board is the likely cause. For a 1201 with a serial between 832172 and 8981138, the Norcold 621271001 power board or the Dinosaur 6212XX fits.
