How do i get my channels to come on

yes so press the menu button , once the menu pops up scroll down to channel then click the right arrow then scroll down to anything meaning auto scan channels then click on that and then put your remote down and in a few minutes it will finish scanning and it should close menu and go straight to one of the scanned channels, once this happens you should treat your tv normally and go through the channels until you find something you want to watch and so on, your done. If this does not take care of your problem feel free to get back to me asap. THKS!

Auto channel scan finds the local channels available over the air so that when pressing up/down channel it only goes to those channels
