Setting the Sprite Renderer off and on of a secific object

I need to make like a pause menu but I need to turn off the sprite renderer of an object that DOESN'T have this script on it. I have just got some pice of script done but I still need help whit a variable, to turn off the sprite render of an object that I can type in his name in (P.S. the name is Live1Icon and it is in Start so don't worry about computer power)

Code (CSharp):

1.  
2. else {
3.          GetComponent(MeshRenderer) = false;
4. }
5.            

 

yes sure, and a SpriteRenderer is not a Meshrenderer

Code (CSharp):

1. GameObject.Find("Live1Icon").GetComponent<SpriteRenderer>().enabled = false;

 

Thank you so much !
