I heard a loud bang from a lightning strike really close this morning. Now my TiVo will not come on. The light on the front of the TiVo Roamio OTA lights, but I get a blue screen on the tv. I unplugged it and rebooted it several times and the light on the front comes back on, but that is it. Any help? All of my other equipment works fine and it is all hooked together with HDMI cables. Power in house did not even blink.
