I agree. Probably a cracked ciruit board or cold-solder joint. Or shorted

Get off your lazy ass and consider it an adventure!

If you can get the board out, it should not be that hard to find the
crack or open circuit board trace or had solder joint. An open LED will
only affect one LED. A short will not allow ANY of the LEDs to light.
