I waited in line for the 20" tv/dvd from walmart. I bought 2, one for us, one for my son for christmas. We set up our tv in our room last night and went to watch a dvd, and it doesn't work. It is a stupid no name tv. I called the company they told me to return it. I called walmart they said I can return it and put it towards a 180$ tv. What do you think the chances are that I can get walmart to give me a different 20" tv/dvd to replace it?
