I am the owner of this specific remote control, but I have the following problem. On an LG TV, obviously an old model, the 4 programming buttons were working fine. I tried to program the TV/AV button to INPUT/source and it didn't work, and it was probably my remote control's fault because it wasn't working properly. The result was that I got confused and also programmed the Power button, so now I have 2 unrelated buttons. So be very careful when you try to program, make sure that your existing remote control is working properly. At least the buttons you want. I will give it 4 stars because it is excellent in other aspects. The missing star is because I was looking for a way to reset it but I couldn't find anything... However, if someone has any knowledge, please leave a review below or send a personal message!!!
