That sounds like the front board is locked up or failing. The dim display and unresponsive buttons point to it. First, disconnect the 12V for a minute and reconnect it. If it's still stuck, the optical board is the likely cause. For N410/N412s with serials above 9140559, the 628663 is available (2–3 week lead time). Send us your serial and we'll confirm.
