Yamaha DTXpress/DTXplorer/DTXtreme

I no longer have a rim sound on one side (left of the centre) on one 
of my TP80S cymbal pads.

[sigh]

Looking at OldGuy's pictures, it seems that the rim switch splits 
there, with seperate tracks on the ribbon back to the PCB. How 
straightforward was it to take the TP80S apart for your photos?

Anyone familiar with the failure modes of this switch? Is it likely 
to be repairable? I'm not an electronics whizz, but I can fly a 
soldering iron.
