If you want to get rid of the volume icon on your TV, there are a few things you can try.
First, if your TV has an on-screen display (OSD), you may be able to access the settings menu and find an option to disable the volume display. To do this, simply look for the menu button on your TV remote and navigate to the appropriate setting.
If your TV does not have an OSD, or if you can't find the relevant setting, there are a couple of other options you can try. First, consult your TV's user manual - it may contain instructions on how to disable the volume display. If not, try searching online for your specific model of TV + 'disable volume display'. This should bring up any relevant forum posts or support articles that can help you solve the problem.
Finally, if all else fails, you can always cover up the volume icon with a piece of tape or something similar!
