Follow these steps to reconfigure your Slingbox to support your new set-top box.
Note that the steps are somewhat different for newer Slingbox models versus older ones, so be sure to go to the correct section. There are also steps to reconfigure your Slingbox using Slingplayer on your mobile device.
Open Slingplayer for Desktop on your Windows or Mac OS computer. Select your Slingbox from the Directory. (You may need to log in to your Sling Account).
Depending on whether you have a Slingbox M1 or a Slingbox M2 ...

Follow the instructions to add a new AV device, and you should be good to go.
Using your Windows or Mac OS X computer ... go to newwatch.slingbox.com and connect to your Slingbox. (You may need to log in to your Sling Account.)
Click Settings, at the center-top of the screen.
The Settings screen displays.
Click Configure Input.
The Select Video Input screen displays.
Click the "x" next to the listing for your old set-top box model.
The input now says Unconfigured.
Make sure the proper input is selected (most likely it's the one that you just worked with), then click Next.
On the TV Service screen, select your TV programming provider. Click Next.
On the Channel Lineup screen, confirm that you're seeing the correct channels. If not, click Back to reselect your TV programming provider. If all's well, click Next.
On the Set Up Your Remote screen, either search for the make and model of your new set-top box by typing the box's make and model in the white field ... or click Pick to select from a list.
Once you've selected your new set-top box, click Next.
Follow the directions on the Test Your Remote screen to make sure that everything works correctly.
If you see a dialog box that says We detected an HDMI video source, answer SAME if you have both the HDMI and the Component video cables connected to the same set-top box. This is very important!
If the HDMI and the Component cables are connected to different sources, click DIFFERENT.
You're all done! Enjoy your new set-top box.
