2004 DVD system Problems??

One day my daughters were waiting in the car watching a dvd, but with the key turned on instead of to acc. The blower motor drained the battery to the point that everything shut off.

Now after I had charged the battery back up and got it going the lcd screen no longer turns on when flipped down, like there is a blown fuse, but I checked all of the fuses and they are good. The dvd player will pull the dvd in and eject it but it doesnt seem to play anything, there is no sound anyways. The stereo still works fine as does the rear ac controls. Has anyone had a similar problem and how did you fix it?

Thanks
Steve
