Hi Ragnasty,
Welcome to the Heartland Owners Forum and Family. We have a great bunch of people here with lots of information and all willing to share their knowledge when needed.
I'm sure you will get some help with your dvd soon... I'm thinking it happen to me for a couple times and I found that I had a bad connection on one of the cables out to the TV. Mine quite completely a couple of weeks ago, so I will be replacing it soon. You might check with another cable or check connectors.
Think about joining the Heartland Owners Forum and making some of the rallies when you can. You will meet some of the best people and eat the best food around.
Enjoy the forum and your new Elkridge.
