Just got it yesterday. I had it hooked up to my tv via component cables. Everything was going well. Then Today I took it over to another house. Hooked it up via hdmi. Everything was great. Came back to my place, tried to hook it up to my tv, and nothing. No video coming out of it - no audio. Then I unplug it, try to hook it back up. Then I get audio - no video. Then I unplug it and then no video or audio. Any suggestions?
