AppleColor Rgb Monitor (For IIgs) Adjustment?

Hi all,

I've looked many placed for a service manual for these, but never have been able to find one.

I just rendered the flyback, and replaced all the caps on mine. Since it's all apart, I'd like to adjust this to factory specs, as I'm sure it's out of adjustment.

I know there is a built in screen for adjustments for example how do I go there?

What do the knobs on the back do? When should I adjust them?

What about the focus know on the flyback?

Anything else that requires adjustment? I know there are three black and white little levers inside and I'm worried I may have moved one a really small amount. What does it do??

Thanks!
