Hi there and welcome
The simplest method is to use a Chromecast Peter, as your TV does not have the app
You can purchase this from my link below
Then you install the app on your smartphone or tablet from here
And send it to your TV, where it will play and your phone or tablet will act as a remote.
If you would like any additional information or assistance, please do not hesitate to let me know.
Else if you can take a second to rate my service by clicking one of the stars at the top of the screen then submit, that would be greatly appreciated.
