error msg cl-17,data light flashing on tv box,no caller id on tv screen
Yep, same thing here. Hours on the phone with Comcast support. On Demand error CL-17. It's a system error. Nobody seems to know how to fix.
Demand a new cable box. Comcast made changes to X1 system rendering some cable box models incompatible. They should send you one overnight and waive all charges.
