Do you mean a 1698? or the 1797? If it's really a 1798 then it's new to me.
If you were not the first one in there, then all bets are off as to what may or may not be the issue with that thing.
Magnets could both be in backwards.
If it's a 1698..
Make sure R38 is on the MCU board (top side left edge)
Make sure U9, R37, R41, C32, C34, C35 are on the MCU board (bottom right) and there is no PCB damage around there.
