No picture with Samsung HD-841

I'm hoping someone can help me out here. I have the Samsung HD-841, the Samsung HLP5063 and the Denon 3805 receiver. Everything has been working great, but today my wife was babysitting for a friend and apparently the toddler was playing with the remotes. Everything works right when watching cable or the vcr, but when I try to watch a DVD the screen is black, but I can hear sound (although the receiver doesn't automatically switch to Dolby Digital like it should, it stays on Dolby II music mode - which usually it is on only at the menu).


I've checked the connections with everything and they are all good. I just have no idea what button could have been hit to cause this to happen. Any ideas???
