It might be easier to find a CRT than a flyback transformer, but perhaps both of yours are good. If you don't have a CRT tester, this article explains how you can test the CRT's filament to tell if it's a complete dud:

A picture tube can have a good filament yet be too dim to make a brilliant picture; it might make a good enough picture to get you through the restoration, anyhow.
This site has lots of TV manuals, but I don't see your model listed there unless it's covered under another model number:

Tube TVs are similar to tube radios, but more complex and with higher voltage. This section has some TV restoration articles that may give you a general idea what you're getting into:
