Re: [IA] Turned on TV for first time since Superbowl Fail So you're telling me that if your water stopped working you'd just sit around and make a couple of calls about the issue. Then when someone offered to come out and look at it, you would refuse the call?
If your electricity was blinking on and off, you wouldn't call the power company and have them come out and see if they can find the problem?
You're right, you don't have to babysit them, but they can only help you as much as you want to be helped.
I see that you called Tech support and they offered to roll a tech and you refused. I see MediacomChad also suggesting the same thing. In my experience some of the customer reps do default just to roll a tech but MediacomChad has resolved MANY customers issues.
Tiling could be as simple as old worn out wiring, a splitter or amp that has gone bad, or the signal being split too many times without being re-generated. These are all issues that would reside within your residence. As you stated that this is a historic building a likely suspect would be wiring.
