TV went out, easy fix.

It is possible the port went bad. More than likely what really happened was your input source selected was changed from HDMI-1 to HDMI-2. Or.....if your wife is anything like mine, she rearranged the furniture (monthly at my house) and unplugged the cord and plugged it back into the different HDMI port.

In most cases it is easier for a tech to tell you to change the plug than it is to talk you through the process of changing the source input when the process is different on every brand of TV.

thinking out loud, and I've never seen this happen, but maybe HDMI-1 had a corroded connector?

I know how to check source before I call for help. Spectrum tech went right to hdmi after I told her what I had already checked. This was all on a phone call BTW. I have a neighbor who has lost 3 out of 4 hdmi ports on one of his tvs.
It must be fairly common for tech support to go right to it. I had just never heard of it and wanted to share.
