This would all be guessing without some more information.  Of course, look for the obvious such as a blown line. Check the fluid levels.

Does the dash look ok?  Everything functioning and reading properly?

Examine how the hydro power is generated and that the pump is functional(belt, gear driven, electric).  Bad belt, blown fuse?  Is the pump really hot?

Is there any pressure at all in the lines?  Look for stuck relief valves, broken pressure springs.  Do you have a gauge to read line pressures?

Safety switch?

My TIMBCO did the same thing. Ended up being no pilot pressure. And yes always check the door safety switch first.
