To summarize, one of the hdmi's on my st50 (hdmi 2) stopped working all of a sudden. This happened when I plugged in a chromecast in the hdmi. I've done a lot of tests and it's def the port. I checked to make sure it was turned on and it was. I reset the tv, i unplugged and plugged in. No luck. The other two work fine. Any suggestions on how to fix this or is it toast? I looked at the hdmi port and it seems ok although the fit doesn't seem as good as when I plug the cord into the other ones. That;s the only difference I see.
