First disconnect the boards that are together in the center (sometimes it just takes a little wiggle all the vibration from playing), the primary board where the modes are that is typically the failure issue, as it sends the signal to the other 2 boards above (torpedo's ) and below (Captain's chair & shoot again)
The left spinner looks like just RED is out, try disconnecting it as well. Since this is a separate LED, more than likely a resolder or RGB replacement.
