Quoted from gdonovan:Possible indicator that circuit is not functioning as it should?
Maybe that is causing the problem. This board doesn't look very healthy as a result of the leaking batteries. Are you sure there is not a trace somewhere eaten away? Did you check if the all the addresslines and datalines are ariving at the RAM socket? I assume you did replace D23 already!?
