Becky or another Cox rep could you look into this issue please, and get a expected resolution time.
This should be a known issue, I cannot believe it has not been fixed yet.
There are numerous parts of Peoria, Glendale, even Laveen, were the SDV Tuning Adapters are not working, It is pretty wide spread in the Phoenix area.

When I called Cox this morning for my relatives in Glendale, Cox said they were aware of the Tuning Adapter outages, and had techs working the issue.
I am not affected in SE Phoenix, I am on a different cable plant.
