If the fuses and RV power check out, measure the 12V DC right at the power board terminals, and check the polarity and the fuses on the board itself. A completely dark display with good power at the board points to the power board or the ribbon cable to the display. For the N641, the in-stock boards are the 628661 and Dinosaur 6212XX. See our won't turn on checklist. The N641 is discontinued, and Norcold's replacement is the Norcold N7X. See our Norcold replacement guide.
