Graphic Problems (Glitchying graphics) with my MVS MV2F (2 slot mobo)

[Wolfie79]

Hey there!!
  I recently bought an MVS A 2 lot MV2F, having some big space problem at home, I`ll have to part from my Custom Built Cab with a 25inch CRT and a MV1F mvs in it, so I decided to still keep an MVS (cant live without neogeo ffs!) but a consolized one, now first problem I have is to do the job myself since I am not very very skilled at soldering, however with patience + loooots of coffee    i`m sure i`ll manage somehow, only issue is after lots of googling around and stuff, I cannot find a simple step by step tutorial to do the job, after all `im no electrician and not technical at all (i`m into media and software not hardware ) so any clues what sort of tutorials I should be looking for?

  Btw i`m from Malta (europe) and no one around on this island even knows what an MVS is

I am sure it is something to do with the graphics chipsets, however I have no idea which one has to be re-flowed/checked and even how to check which one, here is a video btw of what it is doing, sound is fine (as you can see in the end of the video)
