Remote no longer changes volume on TV
It's always struggled sometimes but usually if I restart or charge it, it'll work. But it no longer changes volume no matter what I do (tried changing volume change settings and all)
The remote uses IR to change the volume, it comes set to a default setting which works with most TV's and receivers, in some cases it doesn't and has an option to learn obscure settings used by some equipment. It may be that someone has fiddled with the learning settings and they are no longer at default, you may need to learn your TV's IR settings over.
