The usual for me is to unplug it all, remove power and wait 10 minutes then apply power, then test that one port again. If it's still failing arrange for repair.
While the family and I were on vacation there was a lightning storm. My home took a lightning strike. At least I think that's what happened. We came back from vacation and the DirecTV receiver was not working along with the Century link wireless modem. Also the HDMI 1 port on my new Samsung TV not working. DirecTV and Centurylink replaced everything on their end and that's been fine but the HDMI 1 will not work. The other 3 ports are fine but HDMI 1 just will not pick up a signal. I replaced the HDMI cable and most everything else. What should I do?
