Got them working again this morning!
Plugged in the Chromecast. Found the correct input on the Dynex by (duh) scrolling through.
Started the vid on the phone and clicked on the “cast” icon. Can stream Youtube, Prime and Netflix. Found http://watchnewslive.tv/
Also changed the clocks. The only tricky one was the LaCrosse in the living room. Held down the reset, then when the “hour” was blinking, let go of the reset and clicked on “-“.
Ron diligently cleaned almost all of the window sills and the sliding door track.
Tomato soup, grilled cheese and a big salad for lunch.
Laundry. Changed sheets.
