If you are trying to watch over the air TV you will need an antenna. Connect that to the antenna input on the TV. Run the channel scan so the TV can find the available channels.
For internet sources you will need to follow the manual of the TV. If the TV requires a wired connection you will need that first.
For other sources each would connect to the TV (probably with HDMI). Make note of which input you used for each. Select that input on the TV remote. You might have to scroll through the inputs if the remote doesn't have direct buttons,
all my hdtv's on there remotes have a button called ''input or source '' with it you change say from tv -hdmi 1 -2 or 3 pc [if vga port is used or what ever else your hdtv is capable of doing port wise ] or what ever just check that and see if the setting is on TV ??
