I have LG TV UF6800. TV is working well. The youtube app had worked well until a couple month ago. The yoyube hangs very often after playing advertisement. It also hangs after playing a long video (around 30 min). By "hangs" I mean it is still there, showing the youtube UI, but we cannot play any video. Just black, staying there forever. I am using wired network on the TV. I tried updating app, nothing. I googled and tried unpluging power while watching...., no help. BTW the youtube (with the same user) works well on PC and iPad. If you think this is not LG's problem, please advise to whom I should contact. Bogang Tian
