box won't turn on no signal

My cable box won't turn on and my TV shows that there's no signal. I've checked the connections and they're all tight. Any siggestions?

Call Comcast and have tell them the problem. They likely will try sending an activation signal to the cable box. If that doesn't work, make sure that all those tight cables and connected to the correct places, cable box output to TV input, etc.
