I have 2x Roamio Pros on Cox. Everything was working fine for years until recently my wife said some channels were not coming in. Figured a tuning adapter issue, so I rebooted it. Never came back - just a blinking orange light. Other TA was solid orange (as expected) and everything was working on that one. Made the mistake of power-cycling that one and now neither TA works. Just endless blinking orange. Swapped out the TAs at Cox, same thing. Now they are sending a tech. Roamios don't recognize there is a TA plugged in. One is on TE3 and one is on TE4. Premium channels work fine. Tried leaving them plugged into just coax and not USB for 30-60 minutes, tried rebooting the TiVos with and without the TA plugged in - always the blinking orange light. It is a steady blink with no pauses. Occasionally I will see the red message light for a second or so. These are the Motorola TAs. I was hoping when they swapped they would have something different. Wondering if anyone has any advice. I am using MoCA in the house....but have been for nearly 10 years.
