Hi,

Very sorry about the response you received via our email service. We would be happy to try to assist with the problem. It would be difficult to know what changed from when you went into the settings, to now.

Generally speaking, when the TV is on and you connect a cable to it, it will switch over to the input related to that port. A suggestion would be to leave the TV on then disconnect each cable and reconnect them.

If that does not work, you can reset the TV to the default settings via the Options menu.

For further assistance, call our Customer Service line at 1-800-243-0000.
