Title: Neo-Geo 2-slot problem
Post by: AE35 on May 22, 2010, 03:56:26 pm

Hi guys :)
 
I just got a faulty Neo-Geo 2-slot board. Whether a game is inserted or not it only displays some
white squares(9 of them) and some strange characters at the top, while flickering a little.
 
I'm a Neo Geo newbie, so I know nothing
 
The board has some battery corrosion, but it doesn't seem very bad, and I've removed
it as good as I can.
 
Any advice as to what my next course af action should be? I would really like a guide, but
haven't been able to find one...I would also really like a component drawing, so I can see
what IC goes where, if I'm to put in new ones
 
Thanks, hope somebody can help:)
 
Nicholas

I'd clean the contacts on the mobo where the carts go in, and the carts themselves. there are other possible answers but this is the classic starting point.
