Well, Just got my Neo Geo MVS 4-25 Ver. 2 cabinet working on a 2 slot board. My 4 slot board has a back up rom error. So at least I can play it and thats the most important thing RIGHT! But this little board that switches and illuminates the luminecent paper for the marque is squealing like a stuck pig. I originally thought my PCB's audio section needed re-capped. but I kept hearing it even when the sound was turned all the way down. SO what part needs to be replaced or checked on this board for its loud noise. And none of the marque spots light up either.
thanks for your help in advance.
