I have a TCL 65X4US and it has been working great until yesterday it wouldn't connect to wifi. I tried to turn wifi off and on, but after turning it off the wifi setting would not go back to on. I am now also unable to pair my air remote to the tv, which it could do before. I have tried rebooting the TV, turning off the power point for 1min and then back on but still can't turn wifi on. Any help would be appreciated.
Cheers in advance
It’s time to perform a full factory reset on your TCL TV.
Factory Reset Procedure:
Press home on your remote to open the main screen.
Scroll down and select Settings.
Press the right arrow button, scroll and select System.
Press the right arrow button, scroll and select Advanced system settings.
Press the right arrow button, scroll and select Factory reset.
Press the right arrow button, scroll and select Factory reset everything.
To proceed with the full factory reset, enter the code listed on the screen and select OK. A different code is generated every time you reset the TV.
