Various online resources say to hold down INPUT and VOL- on the remote while plugging in the TV. This doesn't work, at least on mine. Hold them down on the TV while plugging in the TV, that works. Then you press VOL- and CHAN- on the TV, to get into the menu. Channel buttons select, volume buttons alter.

Unless you did something special in your settings, I'd suspect a physical problem with the button on the TV

I just picked up two second hand 40" Sharp LE40LE700X units and they were set to hotel mode. This guide was the only one that helped me fully unlock them (change Public Mode to Off).
Thanks so much!
