[TurboGuard]

So I managed to snag a Toshiba 35AFX54 for my retro gaming set up, and initial impressions are really good. Everything is bright and crisp, convergence and geometry is good, but my greyscale is more like a greenscale!
So I got the service manual and looked at some values and my GCUT was nearly twice as high as the others.
I want to get it adjusted the best I can without any fancy equipment just so it looks pleasing to my eye, but going by the service manual it wants me to open up the back and adjust the flyback first.
Is there a good way to adjust these settings without resorting to that? I do have access to some test patterns using the 240p test suite.

1) Write down the original values..

2) The RCUT Values change the dark grey scale, but it has quite a huge effects on the entire grey scale.. A grey scale ramp is a great test pattern to use..

3) Very important about the Cut Values.. If they are too high, they will have impact on the black level, and turn black into dark grey.. when one color is too bright, of course this color will be dominant.. Also if they are too low.. black crush.. So all 3 Cut Values work like a black level/brightness starting point..

4) Usually the RGB Cut Values are similar or have the same Value.. So a much higher green number is quite unusual.. Reduce it..

Thanks for the tips!
Should I set the Contrast to half and brightness to max when I set them, or something else?

Contrast is light output.. I would not use max, but a medium setting that you would use for using this tv
Brightness is the control of black level and/or lightness of the picture.. Idealy use the stock setting (reset) or the setting that seems to be in the Middle..

Brightness too low = Everything gets too dark
Brightness too high = washed out picture, everything gets lighter (not brighter)

So there is another fairly annoying issue with this set...on the left side of the screen the image slightly squishes so it makes horizontally scrolling content appear wavy.
Apparently it has to do with horizontal linearity, but I don't see any option in my service menu to adjust such a thing.
Am I screwed?

Turn R, G, and B all the way down.
.....
Then turn red up till the screen is red
Then turn the blue up till it is violet
Then turn the green up till it is white
