I removed a keyboard that is used to communicate with radar assembly because the operators complained that some burn smelled (indeed it did). Opened it up and found a couple of places on PCB with white stains. Cleaned it with electro-cleaner, put it back and now one part of the keyboard is not working.
Did you ever have your PCB damaged by electro-cleaner? Like, is that even possible? When you use electro-cleaner, do you need to wait for it to dry before installing the PCB again?
My other ideas are that I touched a PCB with my hand and damaged it by discharge or that, while removing it, I damaged the cable connecting keyboard and PC (this one is hard to tell cause everything is so cramped up and inaccessible).
