Tragically I spilled a beer on my Leopold FC900R and two keys stopped working even after a flush of the board. The left control, and left windows key died. A continuity test showed little to no continuity in use, so I desoldered the switches, disassembled, and cleaned them. After soldering both switches back in place, the left control key works fine. However the left Windows key, while passing continuity for the switch itself, will not work in the OS. I can't see any obvious damage to the board but have not removed the full plate (have to desolder all switches to remove the plate). I've also tried dip switch combinations per the Leopold brochure in Korean.
I've checked the nearby SMDs, and the D86 and D17 diode both seem toast. The other diodes of similar placement are reading about 720 on my multimeter. I suppose the next question is what specific diodes do I replace these with? Or could they be fine and I'm not checking them right? The rest of the keyboard works fine in keyboard tester. And I suppose I'm not fully understanding why both of those SMDs would be bad, but the left control still works.

Thanks for any help provided.
