Not a surprise. The only thing left (temporary short lived solution) is to reset entirely with the button on the TV if you haven't already done that. It's below the ethernet port on the back.
If you have tried it, there's no other solution offered but to get your money back if you still can, or deal with TCL's support if it is still under warranty.
Ok folks. I put in a firestick and use the TCL remote to select firestick, which I’ve set up with all my apps etc. Then your TCL remote doesn’t work, so you have to remember to use the firestick remote. I’ve gone back and forth and there is definitely an improvement with lip sync using the firestick that you install in the back. This helps a lot. It’s $50 but worth it. It isn’t perfect but it doesn’t drift to like a full second delay of visual from audio like it does with no firestick installed. If anyone does this, let me know if it helped you.
