KZ-20EN question (or MC2000S since it seems to be almost the same)

This is in a Frogger cocktail. What should I check for this issue?

I just capped it (pain in the ass to get to some of the caps) but it looked exactly the same before I did anything.

Is this most likely the vertical output transistors (Q401 & Q402)?

I have no idea how to test them so I thought I'd ask before I hunted some down and replaced them.

Thanks in advance.

I could not manage to get that chassis going all the way. I bought another untested MC2000S and it looked like this before capping it. I capped it and it looks the same. The color is washed out at the top of the monitor, that could just be adjustments, but I am more concerned about the curl.

I swapped out the big capacitor, it didn't change anything.

What else could cause the curl?

Does the curl move/roll across the screen?...or is it stationary. If it's stationary.....look for a horizontal hold pot, or horizontal frequency pot, or some other horizontal XXXX pot. It will usually adjust out with that.

Nope, no movement. I will try pots later.


You were correct. I was shotgunning things and forgot to check something so basic. Thanks. :)
