Both the Left and the Right button boards are now removed from the Korg Triton Pro.

Here you see the component side of the Left board.

And here you see the foil side of the Left board.

I've made red marks under the three switches that need replacing:  COMBI, PROG, and UP.

Here, those switches have been removed.

I also removed the DOWN switch since it gets a lot of use and could wear out soon.

Here you see the component side of the Right Button board.

And here's the foil side of the Right board.

Again, I've marked the switches that need replacing.  They include the BANK switches and the 0-9 switches.

Here, the 0-9 and the ENTER switches have been removed.
