Was playing around with some old CRT's over the weekend, and trying to convert one as a simple oscilloscope.
Well I got a bit side tracked as I had one TV smoking when I disconnected the horizontal coils. So ended up repairing the TV, one bulged capacitor and two resistors fried, which were in parallel with the hor. Coils.
Coincidentally I held a magnet near the screen and the standard blue default colour produced some amazing magnetic lines.
Here is a short video I made.
