Ginie 34/22 some mechanisms not working

[Hinos]

I'm having problems with my ginie 34/22bi, boom lift,suddenly the platform mechanisms and the drive steering don't work, when I press the steering or the platform command button I can here the pump motor working, also I see pressure in the hoses but no movement, I did interchange the solenoid valves but they are fine on other mechanisms, the steering works wen I press the boom up simultaneously.
The platform doesn't move.
I disconnect the hoses from the platform rotator and oil squirt from both hoses even wen I press any other commands...it's like the pressure it's fighting against each other??
Are this solenoids supposed to close the oil flow completely wen not in use??
Please help.

• All functions get flow from the manifold and all have individual flow paths through valves/coills. Was this a problem that just suddenly happened or was something repaired or replaced prior? You may be getting the pump to activate but you getting that flow to and through the manifold to the functions. Obviously your getting steering. You need to get a pressure gauge and get a reading on your test ports to start. Do you have ground functions or is the machine inop from ground controls also ?

More than likely a wiring issue. Check connections at all solenoids.
