DNLA & Samsung TV - Change in State

Help!

Still getting my feet wet with HA but I feel like this should a fairly simple automation and for some reason it keeps failing on me.

I have my tv led backlights set to turn on and off with the tv which is a Samsung smart TV. The turning ON part works fine. However when the tv turns off it fails to trigger. I’ve tried change it state ON to OFF, unavailable.

Im am really struggling here and could use some advice.
