How to set up xfinity cable box? Do you want to learn how to set up the Xfinity cable box (the practical guide)? Well then you would surely be happy to know that you have found just what you need. You must already know that Xfinity gives you two options when it comes to setting up their TV box. One you can have it installed by their technical team or do it yourself.

So as you have reached this blog means that you are looking forward to self install and this choice might just be the best option for you. Hence here in this post, we will discuss how to self-install every Xfinity cable TV box option that you might get from them and when you should leave it to professionals.

Now all you must do is sit back and read along carefully until you reach the end of this page so that you do not miss out on anything.

The Self-install Process for Xfinity TV Cable Box

This totally depends on your TV; you would need to order one of two options such as an ‘SD and HD’ TV box. Additionally, each may bear the X1, Motorola, or Scientific Atlanta branding.

You must wait 20 minutes to ensure that the TV box warms up. A message will appear on your TV screen when the box is ready to set up. While SD stands for Standard Definition it is also very close to the 480p resolution.

You have two ways to get your hands on the self-install kit that you want. You can choose to order it by phone or the website and receive it through the mail or you could pick it up yourself at the nearest Xfinity customer service center.

Now when you get the kit you should open the box and make sure to check the contents.

Remember that the SD TV box should have the following items:

  • The Xfinity envelope containing Comcast Customer Privacy Notice and Agreement for residential services
  • The Xfinity remote with included batteries
  • Getting started with the guide
  • Power cords
  • Coaxial cable
  • The Xfinity TV box

The HD TV box will contain similar items:

  • Xfinity envelope containing Comcast Customer Privacy Notice and Agreement for residential services
  • Getting started with the guide
  • The Xfinity TV box
  • Coaxial cable
  • The HDMI cable
  • Power cords
  • The Xfinity remote with included batteries

Once you make sure that everything you need is inside the kit then you start setting up the box. It is only a simple two-step process;

Step 1 – Connect and Power Up

You must take the coax cable and plug one end into the wall socket, twist clockwise and finger tighten. Then the other end of the line will go to the TV box into the ‘Cable in’ socket.

You now need to take the second cable (coax if you have an SD TV box or HDMI if it is an HD TV box). Then one end will go to the ‘… to the TV’ port while the other end of the line will go into the appropriate ‘TV IN’ port on the back side of the TV set.

Now all that you need to do is plug the power cable into the TV box and the electrical outlet.

Step 2 – Service Activation

For SD TV Box

On an X1

  • You would need to turn it on and set it on channel 3 or 4 until you see the activation screen.
  • Next, you should pull the plastic tab from the back of your Xfinity remote to activate it.
  • And now you just need to follow the instructions given on your TV screen to activate your Xfinity TV service.

On Motorola

  • You must make sure the TV box is powered on.
  • And then turn on the TV and set it to channel 3 or 4 until you see the activation screen.
  • Next, you will need to go to Xfinity.com/activate.
  • After that, you should follow the on-screen instructions to activate the service.

For Scientific Atlanta

  • You want to ensure that your TV container is powered on.
  • After that, you would need to turn on the TV and set it to channel 3 or 4 until you see the activation screen.
  • You must wait 20 minutes to ensure that the TV box warms up. A message will appear on your TV screen when the box is ready to set up.
  • Next, you will need to go to Xfinity.com/activate.
  • And now just follow the instructions on-screen to activate the service.

For the HD TV Box

On an X1

  • You need to ensure that the TV box is powered on first.
  • And then you should use the TV remote to turn on the TV and set it to a proper signal source (the HDMI port you used to plug in the TV box).
  • After doing so you will need to remove the plastic tab that is on the TV box remote controller.
  • Finally, you must follow the given on-screen instructions.

On a Motorola

  • You will need to turn on the TV and set it to proper HDMI input until you see the activation screen.
  • Next, you would need to go to Xfinity.com/activate.
  • And then you should follow the on-screen instructions to activate the service.

For Scientific Atlanta

  • First, you need to make sure your TV box is powered on.
  • And now you must turn on the TV and set it to the proper HDMI input until you see the activation screen.
  • You then need to wait for 20 minutes to ensure that the TV box is warmed up.
  • After that, you should go to Xfinity.com/activate.
  • At last, you just need to follow the on-screen instructions in order to activate the service.

Remember that the setup process may vary slightly as this depends on the model of the TV box. However, most of the steps should remain just the same.

When you must leave the Setup Process to the Professionals

Nevertheless, the self-installation process is pretty much straightforward. But there are some cases when you may need to leave the situation to the professionals to handle. Or you could even find yourself in a situation where you are biting off more than you can chew.

This is applied to homes and apartments that are without Xfinity infrastructure brought to the property. Setting up the TV box is one thing but laying down a coax cable from the junction box outside itself to your home is a different story entirely.

Yes, at times setting up an appointment and paying some extra to the tech support can be a little of a pain, but it will cost you less in the longer run than the alternative of doing it by yourself and messing up things more.

By following the above steps and steps, you will be able to easily set up your Xfinity cable box. However, if you need any further help you can directly contact the technical team provided at any time. And they will immediately assist you with the solutions needed.
