We are traveling right now and the kids were watching a movie and all of a sudden the sound completely stopped working. All 3 kids only heard static in their headphones. Both wireless headphones and the auxiliary jack. We tried turning it off then back on, tried another DVD, even tried replacing batteries in both wireless headphones. (although if it were the batteries the headphones plugged into the auxiliary jack should still work and they don't). Any ideas? Since we are driving right now ( and have another 5 hours to go) we can't pull the fuse right now.

The movie played fine for the first hour and a half. Now we just get picture and no sound. Please help or the next 5 hours are reply going to suck
