I listed the model number of my HiSense TV incorrectly (sorry). The correct model number is TL2020. My problem was not that I couldn't get my RCA universal remote to program for the TV. I did that successfully and it still works. My problem is that the actual HiSense remote has a button on it labeled "lock" and that allows the user to lock the tv so that it cannot be watched (although it can still be turned on and off, just showing a bar that says "locked" when it is on). I finally called HiSense and was told that the ONLY way to unlock a HiSense TV is with an actual HiSense remote. This seems like a ludicrous feature to me!! I did order a HiSense remote and will simply have to wait until I receive it to watch the TV.

Thanks for trying!
