Had a service call by an experienced technician. Verified cox tap at street, various coax runs. Replaced several connectors and "barrels" and short cables and found a high noise level on one run of coax that is run under a floor. Confirmed that TV would drop out without any "loss of HDMI to a receiver first and then receiver sending HDMI to TV. Bottom line is seems to be fixed. Do have one run of coax with a problem but not Cox problem. If I get problem again with TV will have to determine new way to run Coax to location feeding set top box. Very satisfied with Cox service on the call. He checked every thing and did all he could. Cleaned up little problems here and there but little problems can add up in a whole system. Nosie inside house on coax is the real problem and my problem to fix or not..

Does this make sense? Is the tech suggesting a faulty TV?

What is causing the noise? What else is down here under the floor? If streaming was fine, it has to be something broadcasting on the same frequencies as cable-TV channels. What have you changed in the past few months? Is there an HVAC system down there? Does it have a wireless feature? Did you nail something into the floor?
If this had just started, you changed something. If you had a series of short cable segments joined with connectors and splitters, these needed to be replaced but you had these before the problem, right?
