The first step in solving the problem of a black screen on your Xfinity TV is to check your power source. Sometimes, the problem is related to a power strip, but it can also be a software or cable issue. If you’re unable to find a power source, try connecting the device directly to an outlet. Another way to check your cable connection is by checking the incoming and outgoing coaxial cables. These cables are what bring the Comcast signals into your home. You should ensure that they are connected correctly, and tightened in the slots.
Sometimes, your TV may be unable to connect to the network. If this is the case, you’ll have to manually reset the network. To do this, unplug the router and wait 30 seconds. Then, reconnect it and see if it works.
