My child has autism and does not understand that he can’t max out his tv volume all day everyday and through the night. No matter what we tell him or set a timer or anything. I also can’t just shut the tv off at night as he will just turn it back on.

Is there a secret menu or anything to set max volume? Or an app or anything I can download on my phone or the tv or something to limit the volume? I’m desperate.

Thanks!
