One Minute Fix- Try this method first before going out to buy another TV remote. I have fixed numerous TV remotes (and sound bar remotes) by using this method. With the batteries out and holding down the power button you are basically draining all excess battery. Then by pressing each and every button in and out a few times you are basically releasing a stuck button.
Note that draining the excess battery works the same on smartphones and laptops that is on but you cant see the screen or display. So try this method if you have a laptop or Android phone laying around your home that has a black screen problem.
