    Welcome to Seven Forums.
    Turn off your TV & unplug it from the wall, wait a few minutes & reconnect it & turn it on.

    You could try resetting your TV to factory defaults. Refer to you TV handbook if you have one. Operate your TV without having it connected to your computer & have the antenna lead connected. Use the menu on the TV using the remote control to find settings.

    Hope this helps.

    Hi bennyl1708 and welcome to Seven Forums.
    The problem with using VGA on a TV is most if not all TV's have a low resolution input such as 1024 x 768. The laptop probably sent something the TV did not understand and has messed up the settings. If you have an HDMI input youacould try that. You should have Function Keys and pictures of monitors on certain keys on the Laptop, try pressing those with the laptop connected to the TV to cycle through modes
