Hi guys, first time posting here. I apologise if I inconvenienced yall.
I have a soldered split keyboard, and recently the right half (YUIOP half) starts to act very weird. When I short “U” and “I” with tweezers, I get “UO” or “IO”. Pressing both U and I yield UOI. If I type independently, there is no issue. Also, two other keys press exactly 6 times when I press once, but if pressed in combination, there is no issue. I do not have much experience in solving these PCB issues so any help is appreciated. Thanks.
