Perhaps I ll try to repair it myself, since repairing it in a store will be expensive, and I cant say I really trust them, and also a big fuss due to its size. The service manual is excellent and very easy even for someone with absolutely no experience, and I can borrow an oscilloscope from a friend. But I suck at any kind of craft/soldering/mending, and the CRT high voltage and discharge scares the ---steaming pile of meadow muffin--- out of me. But still, I think I ll might try it. I just want to mess with it it, It looks amazing even when shut down.

I just scored a NOS 25" Arcade Monitor from a Company called "Monitor" that actually built 1:1 Hantarex Polo. I've setup everything that came up in this thread and it's working awesome for the most part. I just have some trouble with some games like Neo Geo stuff. Most games are centered horizontaly and line up perfectly... like MK, SF and many others. Neo Geo is just off. Usually it's too small and I have a pretty big border on the left and some on the right. What can I do about it?

So I checked many games and they're all over the place horizontaly. Some fit perfectly, some are just too small. Is that normal?

Okay I realize it's depending on the game i I have borders horizontaly. What would be the best mode to check the center horizontaly on my arcade monitor before setting up the geometry in arcade osd?

Usually you get more accurate average values when you use a high-horizontal resolution mode. This is so because we can only adjust horizontal values by using blocks of 8 pixels (characters), so the highest the resolution the finest the granularity and the values reported will be more representative as reference ones. Once you get that reference modeline perfectly centered with Arcade_OSD, write down the values and use them as input for a custom monitor_specs line. That will produce modelines with borders close to the reference ones. Don't expect perfection. However if you keep getting modes that are badly cropped or have uneven borders bigger than 2cm then something is going wrong. Not all monitors behave the same. Some are sensitive to hfreq differences, in terms of horizontal shifting. For these cases you need to set up a narrow hfreq range, like 15700-15800, instead of opening it more.
Also, bear in mind that some machines like Neo Geo do have black borders built in on both sides of the frame, this is how the actual game was, so there's nothing we can do about it.
