Will bucket move at all? Is the spool in the control valve moving with the lever? I valve spool in moving, you may have a blown seal in a bucket cylinder. If either cylinder has blown seal , the other will do nothing. Test by figuring out which hose on bucket cylinder will be pressure when you work the control, then remove the opposite hose on the cylinder, then pressure the cylinder and if oil pours out the open hole , the cylinder is bad, If it pours from the removed hose, the opposite cylinder is bad.
