Has anyone had a short throw Hitachi projector (ours is the ed-A110) that has had the door with the mirrored lens which flips down stop working. The motor.runs but the door just swings free as though the rack its on has become disengaged. Its out of warranty and been told it coukd be an expensive repair and not viable. Can it be fixed easily? Sure I read on here someone having a similar issue but cant find the thread.
