Hello Dneice,
Thanks for reaching out to us over our forum! We have an active community here. If you haven't already contacted support since this has returned (following the last visit), then we have a team available to take an active look at the Contour box with you. If you find the issue returns, could you email us at Cox.Help@cox.com with your name, complete address, and some detail of what you see with the display showing boot and the welcome screen?
Remotely, it can be difficult for us to determine if the equipment is defective and need to be swapped, but it is possible to swap equipment at a Cox store near you. You may search here for nearby stores and hours. Before swapping, we may check the network and signal reports from the box with you once we receive your email for support. With an issue that comes up like this, we may better identify an issue if looking at it during the time you experience the issue, so we would like to receive your email and look into that further if it returns next Monday.
As far as steps taken when the box is stuck on boot, is the cable box responsive to reconnecting the power from the back of the cable box? Does the box load afterwards, or get stuck on boot until a particular time? Is there a splitter attached to the coaxial cable between the wall and the back of the cable box? Some folks here are great at providing helpful troubleshooting steps and may chime in to share some helpful advise as well.
