Intermittent Black screen since I changed my box 5 months ago.

Once I changed my box my screen goes black every so often. It sucks to have a 4K tv and need to lower the resolution to watch cable. Comcast need to fix this issue or start refunding customers money.

Hello, @user_v9l3z4. Thanks for posting on our community forums to let us know about this situation. What troubleshooting steps have you taken so far? Have you tried rebooting the TV box manually or through the Xfinity App? Did you check the coaxial connection on both ends (wall plate and TV Box) as well as the Video input (HDMI, coax) connection to make sure it's tight?
