You did not state if your system is electric or hydraulic. I think you have electric from what info you did give us. Depending on your version the reset could be to hold down the power, manual and auto button until all led's are lit. The other version is to just hold down the On/Off button until all led's light up. You may have sheared a pin in the jack and to repair it you will need to remove the jack assembly and first pull the motor and gear assembly and check the pin in the worm gear. If it is ok, there are other pins in gear box and jack. Once repaired, use a 12 volt power source at each jack and power them through the quick connector (separated from harness) until they are 4 -6 inches below full up. Reset controls and do a retract all. Good luck and keep us posted.
