If it runs on LP but the keypad won't respond, the front optical board or its connection to the rear board is the likely cause. First check that the ribbon cable between the boards is seated and that you have a solid 12V. For the N821, serials below 9126825 took the 637779 kit (discontinued), and serials above that use the 628661 power board with the 628974 optical board (also discontinued). Send us your serial and we'll confirm.
