My Panasonic VIERA TC-P50ST60 won't stay on.

My Panasonic VIERA TC-P50ST60 won’t stay on. It turns on using the remote, but it turns off when I hit any button on the remote, not just the power button. I can’t get into the menu to reset to factory settings because the TV itself turns off as soon as I hit the menu button. I tried to unplug for awhile, changed remote batteries, nothing seems to fix it. My 2 year old daughter did get ahold of the remote while I was in the other room, is there some mode she could have put the TV into that makes it shut off constantly?
