Hi guys, I have an AES which i have had problems with now for a long time. So here is the story. I bought It second hand and when i fired it up for the first time all I got was messed up graphics.
So I decided to attempt to install a diag bios, by removing the old one and putting a socket on it. Well I fudged it up in a big way and left myself with a very damaged board. I since rewired all the missing connection and finally got it working again in the state of the above video. I was then stuck and didnt know what else to try, the diag bios tested and came back all OK, i had tested the pallet ram connections and all was connected. The only thing I didn't have was another game just in case it could have been that.
Unfortunately life got in the way and I couldn't afford to buy another game to test it, so I put the neogeo into storage. 3 years later I was re stumbled upon the Console and was in a better position to now be able to purchase another game and try again to restore this console. but this wasn't to be as now the thing will not power on. The board revision is 3-4 and is a pro-pal (5v3a or 9v3a). When I power it I get the watchdog clicking noise and black screen, I have traced and checked all bios connections using http://www.jamma-nation-x.com/jammax/tutorials.html#aesbiospinout and all is present and correct. Please im now again stuck and really want to get this working again.
