S-Video Port intermittent; probably forced/damaged

The machine was moved with the S-Video cable attached and likely pulled hard enough in the process that damage occurred. There was no gradual degradation of the connection/signal.

When very lightly touched, the signal goes from fine to "squiggly and darker" and back again. There seems to be more play to the physical connection than there was before.

-Am wondering if replacing the Logic Board is the only option for repair, if the jack/port is loose or broken free.

Thanks for your consideration!
