@SteveH posted:Good suggestion John. Would you also suggest removing and re-seating the micro-processor chips in their sockets as well?
Only if you have or obtain a PLCC extraction tool, then you can reseat the two PLCC chips. However, do NOT try to do this by prying them out with a screwdriver or similar utensil, that will almost surely break the PLCC socket and then you do need a new sound board!
