I have just set up my new smart stick with entertainment pass but the picture is very poor. For a couple of minutes it will be okay and then it will go very pixellated and it's hard to even see who people are or to read text on screen. Netflix works fine through the stick but the channels available on the entertainment pass are really bad. I've tried what I can in the trouble shooting guide. I've also reset my tv to factory settings. Can anybody help advise if there's anything else I can try?
