IR remotes are easy to test by pointing a remote at your phone with the camera app on. Then when pressing one of the remote buttons you’ll actually be able to see the IR beam emanating from your remote on your phone camera app.
Using such a method, you can test all buttons work on your remote and actually video any failures buttons.
Sometimes IR remote buttons stop working because some liquid may have made its way under the rubber button membrane and onto the circuit board and dismantling it and a clean using isopropyl alcohol will fix it. Sometimes the carbon contact fails on the rubber fingers on the button membrane itself but one can scrape the finger and cut and glue foil on it, that way electrical contact can be made and the button works again.
Obviously if the TV & remote is under warranty, or just outside warranty, take the issue back to the selling retailer and show them the failure video. Usually retailers should be able to sort you out on the spot.
If all that is too much effort, I wouldn’t pay $100 as, IR remotes cost less than a cup of coffee on eBay
