Faint repetitive 'helicopter'-like sound. motorola cable box has been rebooted and all cables have been checked for tightness. New vizio tv and now cable doesn't work I bought a new vizio flat screen. I think I have everything plugged in correctly (internet still works, and cable is running from the "to TV" port to the tv.) The power on my motorolla cable box is on. When I switch the settings on the tv to "tv" (I've tried them all: tv, av, component, hdmi, etc.), the text 'no signal" is displayed. It was working on the other tv, but now it isn't. Is it possible the cable box I have is so old it won't transmit the proper signal to the new tv? Thanks!
