    Default hitachi seiki ht 20 fanuc cnc lathe turret trouble

    At my fathers shop we have a 1986 hitachi seiki ht 20 fanuc system 3T model F cnc lathe and the turret has stopped responding. I have tried changing the controller to zero home, jog, and handle jog to no avail. I have also tried holding down the 3 keys like some other forum posts have recommended to reset the position among other things which didn't work. I have tried to manually turn the Z and X axis screw, they move but it has not helped. I have also inspected my hydraulic fluid and it still creates enough pressure that it should move. I do not know a lot about the parameters or the electronics and I have tried looking up the old manuals but it's hard to understand them with my little knowledge in that field. If anyone can help to solve this issue that would be greatly appreciated.
