Phalaenopsis fallen leaves

[Lukas90]

Hello!
Problem with my phal is that it lost all its leaves.
It started about month ago, when leaves were going yellow from the center od flower and then falling off.
As for now my flower doesn't have any leaves, but good looking, green roots.
Do you think is there any hope for "rebirth" of my phalaenopsis?
