My 5 yr old son decided to play with the buttons on the TV and somehow got it stuck on Channel 37. I can not get to any other channels (like channel 3, so to view the cable box through the TV). I tried to manualling go to channel 3, but it won't go to it. I would like to figure out how to reset it, so it has all the channels are again accessible. As it looks like somehow he got all channels removed from the lineup, except for Channel 37. There is no menu option on the TV or the remote.
