I have a a TLC Roku 55 inch smart tv.
I have Alexa dot gen 3.
I have 2 oontz bluetooth speakers, both in sync with Alexa.
I can say "Alexa, play music" and it does. "Alexa, turn up volume" it does.
I say "Alexa, turn on Toms TV", it does.
I say "Alexa, play Toms TV on speakers" it says did not find.

What do I need to do to play tv through speakers?
