Cut any of those 4 wires identified in the last step then turn the tv back on

if you get a vertical line then you cut one of the horizontal coils wires
as you may have guessed a horizontal line means you cut the vertical coil
make a note of which is which

*there's no polarity with any of the wires

Now what you want to do is drive one of the coils with the wires that went to the vertical coil (the vertical supply) and put music into the other coil.
The easiest and most likely to work thing to do would be to leave the vertical supply hooked up to the vertical coil and put the music into the horizontal coil.
But you could hook the vertical supply up to the horizontal coil for a longer line I think that looks better but on my newer one that didnt work. Its hard to say how much less likely this is to work statistically its got a 50/50 chance it just depends on the tv you may try it if you like
also you could hook up both coils to your sound source for a dot that expands into a squiggly circle as i said on intro i just didnt like it as much

if you use the horizontal supply you get a flat line that moves up and down with the music which is pretty dull. this happens because the horizontal supply operates at a much higher frequency and pulls the electron beam back and forth so fast that the music dosent have any time to move it before its already crossed the screen

hopefully you can strip wires solder really isent necessary you can easily twist the wires together. taping over your connections is a good idea for insulation but i didnt even do that just make sure your wires arent contacting anything when you close up your case (or when your testing it)

once you have it the way you want it run wires off of the coil(s) your putting music into so you can close back up the case any wire will do speaker wire or whatever else just put it anywhere on the edge of the case as you seal it back up and it will be held in place(picture)

I tried this with a compute monitor and I get no picture on the screen when the horizontal coils are no hooked up properly but it dose make a lot of high frequency noises, Like you said up there, its just a flat line that moves up and down. Is there anything I can do about this or is it junk?

I didn't take the time to make sure all of the wires were right and the tv blew. :(
