My Simpsons cabinet had been sitting in storage for a couple years before I finally had a place to put it. Before going into storage it was working more or less fine. Just FYI, I'm mostly newb, but have done enough research to be dangerous, so please forgive me if I say something that doesn't quite make sense.
Powering it up, everything about the game itself seems to work, the game plays and there's sound, but the image is very squashed and distorted, a band about half the screen height in the middle; it's almost like the v-size is twisted all the way down, or up, whichever way "smaller" is; either way, dialling the v-size pot changes nothing. Twisting the v-hold causes it to start rotating, as it do, through this band.
I replaced all the electrolytic capacitors but it hasn't changed. I think it might be "warming up" faster at least; before putting it into storage I used to have to wait a couple minutes before I could actually see the screen but now it's ready under 30 seconds, so I guess replacing the caps was a good thing, assuming I can fix the real problem.
Can anyone suggest a next step? Everything that I read said this was a capacitor issue, but I suspect cap kits are the go-to solution for most problems.
Unfortunately I've got a Zenith K7000, so I'm hoping it's not a flyback issue, but "squashed screen" doesn't seem to be a symptom of bad flyback that I can find. Hopefully not wrong about that.
In addition to this, it's only showing green: the red and blue drive does nothing, and turning the green drive down makes the screen black. This is also a new problem. I've got leads on this but don't really want to investigate too much unless the above can be solved. I say it only to ask, with two big problems (plus the unfortunate fact it's the Zenith K7000), is it worth fixing or should I just buy a whole new tube and chassis?
