I don´t think that this is a hardware issue.
downscc is right, you operating the flaps with lack of hydraulic pressure is not possible.
So if you do the test and try to drop the flaps with engines not running, you may get Flaps 9, as long as there is some residual pressure in the hydraulic system.
But as soon as this energy is spent, there is no up or down.
Even with engine(s) running you can make the test: Try to raise or lower the flaps with the hydraulic LP valves shut (just below the pressurisation controls), this will cause the same behaviour.
