Check for system update, unplug power, restart.

It shud be there, always there!

Sg version will not work if using with unifi, won't detect u as user.

See ue630x thread.

Try restarting with ABOUT in settings. It loses connection sometimes.

UA6800x is not a gud TV, I already claimed warranty, replacement ck1x, much better model.

i hv not used this 6500x model; last used 6800x but not anymore.

if u do not see youtube, it probably means firmware and security updates have stopped, too old.

my experience with these TVs, u can try updating Playstore first - go to the app and see if u can do it manually.

if this can be done, u can then reinstall youtube from playstore.

if u can't do any of that, it probably means the firmware is obsolete, no more updates... can't do much about it.

It had lines after 2 yrs, replaced foc under warranty. Replacement ck1x is a better TV, been 2 yr now. The AndroidTV is working v well, HDR10.

If, as said by other, that the tv isn't AndroidTV os, can't do anything. Next TV better buy AndroidTV or newer GoogleTV.
