Had the same exact problem; Hisense tv switched off when the Netflix button was clicked. Suspect it was because I was switching off the tv without switching off the Netflix app. Seems to have been sorted by clearing the application cache and cookies. Using remote, go to:
Menu > Settings > System > Application Settings > Clear Cache & Cookies
Note that you will lose your existing login to Netfix and will have to log in again or register.
