greetings y'all!
I just picked up my first Neo-Geo, what appears to be a circa-1993 MVS 2-Slot, and generally it's in nice, very slightly beat-up vintage condition, generally works and plays as well as I'd hope for the $250 I spent on it.
However! There are two outstanding issues with the monitor (one of which is almost certainly a bad trace on the character rom system, as I understand it):
As you can see, I have some horizontal lines in the logo font (and in various other sprites in-game), have seen that addressed in various youtube videos, expect I will have to clean up or bodge a connection between a few pins on mainboard, will figure that out later.
The diagonal lines tho.. that seems like a CRT issue to me, and have seen similar issues described as being due to dry solder points on the CRT neckboard or somesuch...
does that seem likely?
If so, how do I determine which solder joins to check? (is it obvious to anyone, just from looking at this?)
How do I determine what make and model CRT I have?
Thanks in advance,
bx
