Don2: I do see a rca output on the tv. Can I get a connector that goes from headphone jack to rca?
Raudrive: I’m not sure what PCM means but I’ll look in the manual.
Bob999: You may have hit on something. I do have my router connected at 5GHz. I will change that connection and see what happens. Yes I microwave but I don’t use a wireless phone so maybe I’ll be ok.
thanks for all the suggestions. I’ll look into them. At this point I’ve given up on “understanding” the problem. Now I just want fix it.
