After examining your photos, it is clear that your analog board is in good shape. But it is also clear your motherboard is in bad shape, especially in the area of C9. You not only need to replace ALL the caps on your motherboard, but you will also need to use a Digital Multimeter with Continuity Check (make sure it has a beeping sound so you can hear it) in order to fix the tiny copper traces that have been broken due to leaked capacitor fluid eating right through them. Again, refer to your last two photos which reveal that damage quite clearly. Because of this damage to copper traces, merely replacing all the caps will not solve your problems. You have to use the DMM Continuity Check to fix all broken traces.
