Hello, I lubricated the switches on my Huntsman Mini with optical switches.
After the modification, I assembled the keyboard, and the “e” key does not work. I have a multimeter, and I tried to test the photodiode, but the diodes are working (?).
I think the problem is with the board.
I tried replacing the mechanical switches, but that didn't help.
I also wiped the diodes themselves with alcohol.
Perhaps when removing the switches, I bent the board too much.
