I should also add that I've seen those ghost bars on K7000's with the original flyback installed. I put the original flyback back in my K7000 and you can still faintly see the bars, but when you put in a new flyback it gets much more visible. I've replaced every capacitor on my K7000, even the non electrolytic caps and nothing fixes it completely. I heard that those lines come and go depending on the physical location of the monitor. I live in an apartment so I can't really move my machine around to test that theory though.
