I've got the Mac adapter, but when I try to hook up my G4 to my new Vizio HDTV no picture comes up. The TV just says "no signal". Any ideas?

    If your television is displaying a blue screen or no signal message and then turning off, your TV may be at an inactive input. Here's how you can get back to watching your TV:

    1. Powering on your TV and press the INPUT button on the VIZIO remote control repeatedly until a picture re-appears.
    2. If this does not work, try again but press the button slower this time.
