The problem was resolved using VT-25 Solution
"This method allows you to bring up the input menu but you do NOT need to navigate through it. Under the device settings for your TV select "adjust inputs" (next). Then select "Method 4" (next). Hit next again. Where it says "remote button displays source inputs menu" select the remote command that draws up your input menu (on my VT25 it is "InputNext." Where it says "remote button confirms the source input" put "-None-". Then, for each input put the corresponding number button (1 to 0) for each input as seen in your TV's input menu. Your Panasonic assigns a number (1, 2, 3 up to 0) to each input with "TV" being 1, "HDMI "1 being 2, up to "PC" which is 0."
I did not change each input as indicated just input 1. This worked fine. I re-subscribed to DirecTV after a 4 year absence. The TV source is no longer used.
