spring return or power down power up
most likely problem, the valve for jack is NOT opening
could be a bad relay in the control, bad control board, or bad hydraulic valve/coil
manually 'forcing it down', either spring tension or internal vacuum is going to pull it back up
it needs hyd pressure to hold it down
