Sudden Loss of Access to HD Channels
After the Seattle Mariners game ended today we suddenly lost access to all HD channels. When we try to tune to them we get a message saying we need to upgrade to get HD. We pay for HD tier service and have been getting them without difficulty since new boxes were installed a month ago. I started a "system refresh" more than half an hour ago and so far no change.

Good evening @user_vf857y, and thank you for reaching out on our Community Forums—we appreciate you contacting us. I’m sorry to hear that you suddenly lost access to your HD channels, and we appreciate you already trying a system refresh. Have you had a chance to restart your cable box by unplugging it from the power source for about one minute and then plugging it back in? Additionally, can you please confirm that all coaxial cable connections are securely tightened and that the HDMI cable is firmly connected to both the TV and the cable box?
