Hi, so I'm working on my Congo today, and I came across this light board under the lower pf. One of the Congo letters won't light. The traces appear fine from the bottom, so I suspect it might be a bad diode. I wanted to pull the board, but I can't figure out how to pull the board out. It's attached with these spacers, and I can't figure out how to get them to loosen.
They look like the same kind of thing that holds a pin-vice bit in. But normally you would tighten them down from the other direction compared to this light board.
Anyone have any ideas how to remove this board? I can't really get a needle-nose pliers easily between the board and lower-pf, and from the reachable side, I can't get enough grip on what little bit of the space is sticking through to actually pinch it down.
