Contour Cable Box is not sending signal via HDMI out after storms/power outage

We are having an issue with the HDMI out port on our Contour cable box after yesterdays storms. There was heavy lightning in the area and we did lose power at some point but I was at work during that time. All HDMI ports on television are properly functioning, HDMI cables are functioning properly. Cable box was rebooted via Cox app and sends a signal perfectly fine using coaxle to an older TV I had lying around. I have been able to narrow it down to this one specific port. Any suggesions?
