Well, the power itself will be connected to the wall, but you can control the On/Off features with the remote control or the power button.
The channels also would be controlled by either the remote or on the television itself.
Volume can vary. If you're using the TV speakers, you can use the remote, the buttons on the television, or even a universal remote in some cases. If you're connecting your TV to an Audio system, then you would control the volume with that device.
