Reply to VCI broken button?

hey guise.

I packed my VCI into my backpack to go perform at a festie last evening , and all was good except for the right slicer button (or play on normal mapping/overlay). It simply just lights up yellow/orange and won't turn green, send signal, or do anything at all really. I don't really understand why one button will not work when everything is on that one PCB


I'm also not very good at soldering or anything of that sort...so I'm hoping its an easier fix.
