We were living with an old woman who was th Alzheimers for 2 years. Once we’d “repaired” her TV it gave her a lot less trouble (as she couldn’t accidentally switch the source to radio anymore…)

That’s a really good point! Never thought of it that way.

Amateur. The real solution is to take the remote apart, wrap the entire buttons area of the pcb and only scratch/cut free the buttons she needs. That way it still looks the same but she actually can’t hit a button she should keep her fingers off, bc the buttons are disabled.
