Question

When I move, should I take my cable boxes to the new house?

Contact your service provider. They need to activate your new house and may want to install the old cable boxes or give you new ones.

Question

The cable box will not come on! What can I do?

Community Answer

Make sure it is turned on. You will be able to tell if it's turned on if there is a button on the front of the cable box then the ring around the button should be lit up blue or some other color. Make sure that the cable box has some kind of power source and is plugged in with the right cables and done properly.

Question

Why is my box flashing green?

Community Answer

When the box is flashing green, that means that the power cord and coax cable are not tightly connected at both ends.

I have connected everything, but I only get "Welcome. Powering up may take a few minutes." What can I do?

Question

Will I have to pay additional charges to Comcast if I moved my cable box to another TV in my home?

Community Answer

No. You are charged per cable box; it doesn't matter which TV you attach it to. Be aware, though, that the connection (coax or hdmi) may be different, and if you connect an HD box to an older, non-HD TV, you won't get the full HD clarity.

Question

What do I do if it says one moment please on my Comcast box but it never works?

Community Answer

If that's the error message you're seeing constantly on the TV screen, then the best thing to do to resolve that is to call the Comcast customer support. They'll be able to send signals to the box and everything will be fine.

Question

How do I get my TV to stop showing that there isn't a signal if it is connected to the Comcast box?

Community Answer

One of the common causes of that problem is input on the TV. Make sure your TV is on the right input. Click input button on the TV remote and select the appropriate type of connection. For example, with HDMI, select HDMI on TV screen and if it is coax cable, then select antenna.
