Miles' HDTV suffered a power outage and now his HDMI port isn't working. Leo says a power surge likely wiped out the HDMI ports. He should check if he has another HDMI input that he can use. Leo says there may be a fuse that has blown and a repair man could replace it. That could restore his HDMI. If not, it's not an easy or affordably fixable thing. A 64" plasma is worth at least trying to get fixed. The chatroom says to make sure the polarity and grounding is correct on his plugs. An electrician can test for that.
