Science channel 872 and Destination America 873 are randomly distorted and unable to be viewed. I have been on with tech support at least 5 times. They even sent me a new box to no avail.
I am so tired of hearing that same pat answer. If I tighten the cable any more, I'll twist the connector off. And a loose cable would not affect only 2 channels. This problem lies much deeper. As for getting a tech out, good luck. They said when this virus thing is over. That could be months.
