I plugged in a K4700 I bought a long time ago from an arcade and the flyback cracked and started smoking. I guess that's why he sold it to me for $40. The tube has zero screen burn, so it's possible it sat for a very long time in storage. It's hard to say why it cracked like that, but it did somewhat have a picture before and after it blew, so I'm very hopeful I can save this monitor.
