Well, I did my best to solder in that new emitter. It looked okay (not great) and I tried it out. That LED appears to be totally dead now, not lighting up at all and not showing up in the switch edge test. Not sure if it was my crappy soldering job or if the board was messed up. I guess it looks like I'll be ordering another opto board. Thanks for trying! I hope my new board fixes the issue. In the mean time, I'm going to put on some new rubbers and see what other parts I need.
New! Dark mode!
