That sounds like the display (optical) board isn't talking to the power board properly. Try a hard reset first. Disconnect 12V to the fridge for a few minutes, then reconnect. If it still goes blank when you pick a mode, check the ribbon cable, then the optical board. For the NA7LX, that's the 639551, and it's in stock.
