There is a solid state fuse inside the docking station that you can likely replace.
Search the Classic Pronto Forum since dawn of time for
+Bel +Fuse +Link
It is a 500ma Solid State fuse. If I recall correctly, you use a T6 torx wrench to disassemble. You may also want some sort of plastic disassembly tools as there may be clips inside.
You can repair this but be careful taking the Docking station apart.
