Yes, they will work. I usually have about a .3 sec delay between the power on and video input sections. Also, the tv can skip video inputs. IE you can go into the set-up menu and tell the tv not to go to a specific input when you use the TV/Video scroll. I know on some Sony TVs, typically the wide screens, the tuner discrete does not work. What I do is go to video 5, then TV/video once. As far as my memory serves me, I don't think this is an issue with the 53HS. The discretes should work just fine.
