A:
If your TCL has 4 screw holes in a square or rectangle pattern on the middle/back of your television, then yes this mount will work. I've mounted two 70" TV's and one 65" with no problems at all. Very sturdy and secure, and easy to put up and install the TV's to the mounts. It looked intimidating when first opening the package due to the amount of screws, washers, and spacers that come with it; but this is to accommodate more or less every type of television within reason.
Good luck and have a good one!
