If you are unable to find a schematic, best to open her up and photograph the biggest chips and get the chip numbers. From there can get the datasheets, it can also help find the service manual.

That page is about building adapters.

If you want to RGB mod consumer CRTs that is a whole other story. I’m one of the foremost experts at it and I am happy to help. If you can provide the TV model/chassis number and preferably schematics I can advise.
I was wondering if you could assist with a 14" crt tv that I would like to RGB mod? I'd like to get your advise before I get started. Any assistance is greatly appreciated.

Here's the color tv IC:

And the tv manual:

thanks!

Need the TV service manual to really help.

That Jungle chip can usually be modded, it should be able to use the OSD/External RGB Mux method.
