Try leaving on same channel and just wait. Mine switches between one and then the other after about two min. and then after some time passes it mysteriously comes up and appears normal as before. Be patient because this might take a little time. If your experience does not involve the changing of views as mentioned and it just stays on scrammbled forever yes you may indeed have some other problem. I am under the impression that soon we all will need to wait for a fix. Progress!!!
