I run Netflix off a smart tv , but you could download the app onto a tablet, your laptop and run it into your TV (if it's not smart) via the HDMI cable.
Not too expensive for a decent smart TV in LOS though mate ? Powerbuy have got loads for sale I think.
To sign into the app all you need is literally an e mail address and password for the app and voila...
