Here are some articles that may help you get started:

The following section has various TV restoration articles. Skimming a couple should give you a general idea what's involved in getting them to work:

If you don't have a CRT tester, you can check the filament pins of the picture tube to determine whether it's a dud. You can look up the tube here:

Using an ohmmeter, put the probes on the filament pins. For example, on a type 10BP4 tube these pins are 1 and 12. Infinite resistance means the filament has burned out. Bad. Measuring a few ohms means the tube isn't a total goner, although it still might have weak emission and give a dim picture.

One source for Photofacts is the Sams website, https://www.samswebsite.com/ . If you're lucky, your local library (like mine) has a Sams subscription and will give you a photocopy for free.
