My LG SJ4R soundbar is stuck on optical input and nothing works anymore

Solved

Hello everyone, it has been a year since I have had an LG SJ4R soundbar and everything was working very well until yesterday. The problem is that the soundbar remains on the optical source (I tried to buy one, but there is no sound) and nothing is working anymore. The F button doesn't work, the on/off button doesn't work, although when pressed, the red LED blinks. The same goes for the volume buttons. I tried unplugging it, but nothing works. If anyone has any ideas or has encountered this problem, please let me know.

    Pour les personnes qui auraient le même problème, il faut simplement tout débrancher et rebrancher. Une fois rebranché, il faut l'allumer et tout de suite après (rapidement) rester appuyé sur le bouton F environ 15 secondes. Ça la fait passer en mode démo, après tout rentre dans l'ordre.
