I actually agree James sometimes a guitar can just be too broke, however sometimes it educates us all to step into finding out what makes our instruments what they are and 30 minutes of time put into something like finding out why a B string may not be sounding as it should would be an exercise worth doing.
I am thinking the Yamaha may be an older one?
Guitars made today or the ones I have played seem to have their fretboards in order, pitch wise or as in order as much as is possible. Older guitars were pretty hit and miss. I have made several guitars and this has helped me in not just throwing away what may be a guitar that can be saved by even just a twist of a hex screw.

For now loosen off the B string then on the string where it fits in the slot
coat the string underneath with the graphite of a pencil.
Then tighten the string to pitch, play a little then loosen the string while pulling up on the string from the sound hole side (to avoid letting the graphite contaminate any part of the slot it has not lain on.

With a magnifying glass have a look at the slot and see whether the string has sat in the slot properly ( the graphite off the string will show you this) is the graphite apparent all the way from the back to the lip (soundhole end of the nut?
The sound hole lip being the most important
The slot may be too narrow the slot may be high at the back so the string does not touch the slot sound hole lip etc etc.
