I spilt water on my Leopold FC750R but I ended up using it a bit afterwards which caused phantom presses before I unplugged and opened it up to dry it out. After a few days, I put it back together but I found that my B and N keys were no longer working.
I re-opened the keyboard and I didn't see any water damage on the back of the PCB and the area around the B and N keys seemed normal (see picture below). I tried shorting the solder joints of the B and N keys and both were not responsive so I think there's something wrong with the PCB.
I found a thread very similar to my case (https://geekhack.org/index.php?topic=97640.msg3045697#msg3045697) except I haven't replaced the diodes yet. I tried testing the diodes with a multimeter and it seemed okay but is there another way to check? I also tried the advice of the person helping in that thread (https://geekhack.org/index.php?topic=97640.msg3046047#msg3046047) but found when I shorted orange to blue, the "V" key was typed instead of the "N" key.
Any help in debugging/fixing the problem would be very much appreciated.
