Fuji Sfa-257 Shutter Problem

[SpamPepe]

Hello everyone! I own this old minilab Fuji SFA-257 with a digital carrier and shutter doesnt close anymore. If I do checks from minilab menu, and manually close the shutter It will open with no problems, but its stays there. I also tryed switching the wires of the solenoid that handles the shutter and ofc does the opposite thing. So, everything points at the board on the side of the machine, but to be honest I have no idea what to check on there. Any help will be appreciated.
