Hi,
After an unfortunate water spillage, the space bar on my KBD75(ver2) stopped working intermittently. Like it's fine for 30 minutes then it stops working for 45 minutes then comes back on.
It does not seem to be the switch because bridging the pins on PCB gives the same result.
Looking closely at the PCB, one of the diode solder seems to be a bit corroded. Could it be the cause? And would replacing it have a chance to bring it back?
Any way to test this theory without replacing it?
The diode that looks corroded to me is the R82.
Additional question : What are the diodes labelled "Spare resand Diode" on the PCB ? Are they actual spare diodes I can use?
Thanks in advance for your help!
