+Charlie Cat Posted January 19, 2018 Author Share Posted January 19, 2018 (edited) fdurso224 was kind enough to point me towards a broken AES to add to my ever expanding hardware. He thought it would be a good idea for me to share the repairs and the story with everyone. The unit itself is in pretty good shape. It came from a Japanese seller with missing sprites but showing a blue diagnostic screen. Upon receiving it I was able to confirm that it was in the exact condition the seller pointed out. Whenever I have systems like this come in for repair I like to see the issue and then open the console up and see if it has ever been tampered with. In this case it had not ever been opened before and did not show any obvious signs of damage. So no blown caps, obviously damaged traces or broken components. The first step after board inspection is to do the "flex" test. Basically for those not aware, this is literally going around the board while it is powered on and just pressing on chips and tracks of traces. This will help point out broken solder joints and broken traces. In this case, again there was nothing obvious. The next step is to remove the BIOS chip and install a socket. The reason for this is to be able to swap BIOS whenever needed and in this case to install a Diagnostic BIOS. The Diagnostic BIOS returned no errors, so next up was to run the Universe BIOS tests. Again no issues. I didn't expect these to show anything, but it's still a good test. So the next part is where things become interesting. Since this was to be my personal console, I decided to pull all of the RAM and buffer chips that we have seen fail frequently and socket these as well. While doing this, I did find a few corroded traces which I installed jumper wires for, but this did not correct the issue. I also installed known good chips to verify that the issues were not with any of these chips. At this point ruling out the more common chips, it was time to focus on the custom chips. The Neo-B1 handles the sprite layers as sent from the cart. Before checking traces, I went ahead and reflowed the Neo-B1. This doesn't take very long and will help me if I end up having to remove the chip later. The reflow did not fix the issue either. However it did help enable me to drive the sprite layers as I saw fit. This showed me that I could alter the errors being seen on screen. From this point I had to follow traces from the GAD0-3 and GBD0-3 pins on the cart connector to the Neo-B1. Now, this is not the only way to test these, but I do not have a scope in my shop right now and I had to buy a new logic probe which will be here tomorrow, so I was doing this solely with a multimeter. After testing each pin to see if I was getting continuity from the cart slot to the Neo-B1 I found the GBD3, the last one of course, did not have continuity. From this point it was a matter of following the trace to determine where the break was. Many people would just run a new wire from the cart slot to the Neo-B1 and that's ok. However my goal was to keep this as OEM in appearance as possible while also keeping any jumper wires as short as possible and crossing as few components as possible, to minimize interference. After following the trace I found the break was actually underneath the Neo-B1 itself. How this broke, I have no idea. Despite having the equipment to remove the Neo-B1 and repair the trace, I made the decision to use a jumper wire instead of taking the risk of removing the chip and potentially causing additional damage, keep in mind the Neo-B1 is a QFP160 package. After adding the jumper wire, everything was perfect. At this point, the console is good but I am going to replace all of the capacitors since they are TK brand. I also cut the traces running under the crystal to minimize jailbars and I will be installing a new RGB amplifier soon. I know this was a long read, but fdurso224 and I discussed putting the entire story out there for you all to read. I do have a few more broken NeoGeo consoles coming my way for repairs, so if you would like to see or hear more about repairs let me know and/or check out my website. The pictures are large because I take high quality pictures of everything I work on. Also I need to make better labels for UniBios, but please note that the UniBios I am using is authentic. I have permission from Razoola to purchase and burn my own UniBios chips for installations. I cannot sell the chips outright without an install however. Hi mobius, Thank you for sharing this informative posting that you achieve on repairing this Neo-Geo AES console. Glad that I forward you this unit to be serviced and were proud of the outcome that you made out with it for sure. Looks fantastic and thank you for explaining how you were able to get it back to playable condition. Well done bro. It's perfect. Will be more than thrilled to see your future Neo-Geo repairs in the immediate future on those consoles that are on your way. If you wish to make a video of them mobius, we would love that even more. I would also like to mention that you're are now one our maintenance and repair members for our Neo-Geo needs. So, if I happen to get in touch with a member, guest, or see a random YouTuber that is in need to have his console checked I'll forward them to you kind sir. Congratulations. mobius. Thank you as always for your contribution to the video game community and as being a new Neo-Geo AES owner kind sir. Keep up the great work you certainly do. Anthony...

mobiusstriptech Posted January 19, 2018 Share Posted January 19, 2018 Always appreciated sir! I have at least 4 more systems being shipped to me soon. I probably won't go into as much depth explaining the repair and diagnostic process, just to prevent boring people, but I will definitely document the repairs and share before/after photos. If anyone else has additional systems in need of repairs, don't hesitate to reach out. 2 Quote Link to comment Share on other sites More sharing options...

+Charlie Cat Posted January 20, 2018 Author Share Posted January 20, 2018 Hi guys, Back with fellow Atariage member dak1ng ofgames98. Here we see him discussing his Neo Geo CD unit. Glad you have this in your collection Brendan. Nice work bro. From the description, "I'm so sorry guys!! The video cut off before I could hook up my console and show some gameplay. I can post the links to some gameplay videos if you guys would want them. My final rate for the Neo Geo CD is an 8/10. I did notice the long loading screens, and they don't really bother me that much. I would highly recommend getting the Neo Geo CD as a cheaper solution to buying a Neo Geo A.E.S. I DON'T OWN THE RIGHTS TO: SNK, SNK Neo Geo, Neo Geo, Fatal Fury, Real Bout Fatal Fury, King of Fighters, King of Fighters '94, Fatal Fury 3, and Fatal Fury 3: Road to the final Victory."

Hi Mark, Thank you for posting your video with King of Fighters '95 from your Battle of the Ports series. Yes, you bet the Playstation lovers are going to have a field day with the port from the Neo-Geo. But of course, you give a rational view and I'm sure the end results will put a smile on our faces. Thank you as always Mark. Always a pleasure to see you posting on ATariage.com/ Anthony... 1 Quote Link to comment Share on other sites More sharing options...
