Connect two TVs to existing shared antennae so that Freeview works

We have a shared antennae on our apartment and two TVs with built in Freeview. The antennae used to work fine on one TV with all the channels and some channels on the other TV. Now only a few of the channels work on one TV and no channels on the other TV. We need someone to make Freeview work with all channels on both TVs please. We've tried!
