Are you having an issue with your TV?
Purchased this model in October 2016, now YouTube not available. any suggestions on how to overcome this problem?
Should still be available for your model @RRW.
If it's not appearing in the Smart Hub, or in a search (Home > magnifying glass) then try a Smart Hub reset: Settings > Self Diagnosis > Reset Smart Hub.
Thanks for the information, I shall give that a try. regards, RRW
