Hi, My name is ***** ***** certified computer/networking professional with over 10 years experience. I will be glad to assist you with this. .I am sorry to hear that you are having this issue.
No, unfortunately that will not work. The PowerLine adapter signal is carried through the wiring and it has to be connected to the same electrical panel. This sounds like you are gonna need to have an ethernet cable installed in order to get that TV connected.
Okay, great. That will work for you. .
