My fingers, pointing at the red & yellow wires going to the CRT's deflection yoke.

   Next step is to disconnect everything. Most monitors have the yoke hooked up with a single four-position connector. This one has four individual push-on connectors.

   Rule #1 of working on electronics: take lots of pictures, lest you forget how things went together. Take as many as you think you need, then take a few more. You'll thank yourself for it.

   If you swap the positions of these wires, the image will display mirrored, or upside-down. But if you mix the X and Y axes, you'll smoke components on the chassis, and maybe the yoke itself.

   Take photos.
