You might want to check your microcontroller and see if all of the connections look good. Several people have had issues with the microcontroller not being soldered very well. Here is a helpful place to start. It's a comment containing a diagram of the microcontroller pins, and some of the following comments contain details of what other people have had to do.
I'm not very familiar with troubleshooting stuff like this, so sorry that I can't be of more help. But hopefully that will get you started and maybe someone smarter than me can chime in.
Doesn't seem to be the issue.
I had this issue on a previous keyboard (not an Exent), and the problem was that a slightly misaligned diode needed to be resoldered. When I was looking at the diodes it wasn't very obvious at all, as the misalignment was very minor, so I felt like I was guessing. Turned out to be right.
I'm wondering if I have a blown diode or something. All my diodes look good, though.
I've been tracing leads (checking continuity), and I've attached an image of what I've come up with so far. Can anyone tell me where the path should go next (from the question mark)?
BTW green indicates good continuity, while red indicates no continuity.
The red line right the question mark on the top left, they are on different row (row3, row4). but if the red line that you traced out (row3) to the via (row3) isn't present, then there's a problem.
if row3's signal is missing, you should lose "2", "W", "S", "Z", "L Alt" and the 2nd key from top of the last row on the right (from top view).
if you lost all the key as mentioned above, then there's a problem with that row. but if u lost just "2", "W", "S", "Z", "L Alt" , then the fix is simple
