Lightning strike/electrical surge and no longer getting a signal

Today we had lightning strike down right next to our house which cause an electrical surge in the house. We lost two tv's from it and one Xfinity box.  I have tried our other boxes in the cable connections where the tv's blew, and it seems like we are not getting a signal from those cable connections. My guess is that the electrical surge has fried some of the cable wiring. Anyone run into anything like this before?
