I'm definitely keeping my eyes out for another local CRT at this size for the cheap, but I like to work with what I have also and learn as I can. What originally was going to be a "Well damn, oh well" turned into what seemed like a potentially decently fun project, if only for the project itself.

Run the TV through an isolation transformer.

I am rather new to CRT Modification, are you meaning that I should inline an isolation transformer? Or just plugin the CRT as a whole into an isolation transformer? I am assuming this is so I don't create a lovely live circuit through a component jack and fry whatever unfortunate device gets plugged in.

Looking at LA7674 data sheet, RF Video Composite Out is 44, pin 41 is Ext Video Input and pin 43 is the switch to choose between RF & Composite input. Everything is already built-in!

As I read this, it sounds like I can bring in the component video into pin 41, and then run a signal to pin 43 to get it to switch to composite. Am I understanding this correct? Would I need to run the composite in through an optocoupler or is that resolved with the isolation transformer?
Also, I am fully willing to risk and/or scrap this entire tv, that's not a concern to me, so if anyone wants to me to guinea pig any ideas let me know. It's not my only CRT, I have a smaller one that does have component, so I am unworried if this one goes bust.
