Uhm...take a look at the buttons on the front of the tv?
Or try changing the channel? Mine (not a samsung) will go back to cable if you try to change channels.
Is there a setup button on the front of the TV? Look at the buttons on the front of the TV. Other than power, volume, and channel, what is there? Worst case senario? Button mashing!
Something else you can try is unplugging the tv for a couple minutes. Its factory default should be on cable, not line in, and unplugging will make it lose its memory.
