Now i finally got to fiddling around with the controls on my arcade monitor i have found the following after messing around with it.
1) there are two (nearly horizontal) thin lines visible at the top of the picture that i can't get rid off. Except when i turn the image so dark it's unplayable.
Can this be fixed with adjusting or does this mean i need to replace capacitors. It's not that annoying but it is visible?
2) The image in the corners is blurry compared to the center which is really focused. I can't get the corners focused.
Again, can this be adjusted with the controls or should i replace the capacitors.
3) the image is not completely horizontal but a little tilted.
Should is use the "horizontal linearity" control for this? I can not reach it because it's tugged away. I would have to remove the tube to get to it. I will do this only if that particular control is the one i need.
Are there any tips on how to properly set up a monitor (a good order to set the controls)? There are so many potentiometers that i don't know where to start

I have the installation manual but it's assumed that i have a oscilloscope which i don't).
Thanks
