Having trouble getting YouTube to load on older TCL ROKU SMART TV. The load process completes the 100% load cycle then returns to home screen and locks the TV screen; have to restart. I have gone through the process of resetting router and extender, power down the TV with the button while the TV is unplugged, restart TV, reset internet connection and re-connect internet. Internet speed is good. Both Roku and YouTube are up to date. All other channels work fine; loads fast and runs. 07/06/Having trouble getting YouTube to load on older TCL ROKU SMART TV.

You didnt mention your Roku model # and firmware version: Settings/System/About
Known solutions/workarounds for YT app not loading:
1) Check for updates (Settings/System/System updates/Check now) - try again
2) Change your Theme to the Roku Default (Settings/Theme/Restore default theme) - try again
3) Change your Screensaver to a Roku clock (Settings/Theme/Screensavers) - try again
4) Remove YT app, RESTART ROKU (Settings/System/Power/System restart), Add YT app - try again
5) Network connection reset (Settings/System/Advanced system settings) - try again
6) Completely unplug power from Roku for 10-15 minutes - try again
7) Factory reset (Settings/System/Advanced system settings) <--- last resort
Otherwise, you'll need to contact TCL: https://support.tcl.com/contact-us
Always reboot the device, and if that does not work, remove the channel, reboot, then add the channel again.
