Key capacitors and dead key
Hi everyone the middle button on my CA e90 key stopped working. When trying to desolder it I accidently ripped off one copper pad circled red. I managed to get a new button on and continue the trace with some copper tape and both the top and bottom prongs of the button now have continuity parallel like every other button.
However, the key does not work and in the process, I spilt solder on the areas circled blue. I have cleaned up the solder however none of the resistors or capicators whatever they are have any continuity on any side. Is it possible the heat of a solder gun can kill it? Also, I was a bit heavy-handed getting the key out of the original case so it's possible I may have cut off a capacitor and not realised. Does anyone have a key diagram or a solution?
