I had the same problem, which took awhile for me to fix. Ultimately I just disconnected the HDMI cable from BOTH the DVD player AND the TV, then reconnected the HDMI cable, which solved my problem. Not sure why this would fix the issue, but it did. I have to stress removing the HDMI cable from both the DVD player and TV at the same time, because I removed the cable from them individually and reconnected, which didn't make a difference. It wasn't until I disconnected the HDMI cable from both the DVD player and the TV at the same time, and then reconnected it, that it started working.
