I have two 4 slot Neo Geo motherboards that are stuck in the test mode and I have followed all previous treads on how to deal with this. replaced the batteries and they are working fine because it is holding the date and time. I have cleaned all connectors on the main boards and on the cartridges several times without any luck. I do not see any bad traces but it is time to send these to a pro and get them repaired.
