I got the AK33 about 6 months ago after @Zibob recommended it to me and I love it. Only one problem though. Just yesterday the thing started freaking out and inputting keys at a random and really fast rate. I’ve never spilled anything on it so assumed it was a software issue and after looking up what the problem could be, I tried several proposed “fixes” that only worked temporarily.
Finally got fed up and took it apart but at first everything looked normal, so I just got some 99% isopropyl to clean off the PCB. Well, while I was cleaning it I noticed that somehow the solder had ‘jumped’ between two of the keys to make an intermittent connection which was causing the issue (should’ve took a pic, sorry). I just took a small flat-head screwdriver and scratched it off and now its good to go again.
Still really wonder how that happened though.
