My Xbox 360 has always been connected to my Sanyo TV with HDMI cables and has always worked perfectly. I had a movie on my laptop that we wanted to watch on the TV. I hooked my laptop up via the same HDMI cable to the same TV through the same HDMI port. I had to temporarily change the audio device used to hear the audio through the TV. After the movie, I hooked the Xbox 360 back up and now I do not receive any audio or video on the screen. The Xbox 360 works on my other TV, Sharp, with both of the cables I have, and i do get video/audio with the cables and the laptop via every port on the Sanyo. The best I can tell is that there is a communication issue between the Xbox 360 and the Sanyo possibly as a result of the Windows 8.1 and an update or reconfiguration to the TV. I have reset my TV and the Xbox. Any suggestions?
