Thanks for the fast response.
The real panel LED is dead as well, so I guess that means the MCU isn’t running. Could something have been bricked by the arc when I plugged in the power supply?
All the ICs look like they’re well seated (but I did have a problem with the U3 chip; the dot segments didn’t work until after I reinstalled it). I’ll try reinstalling the MCU. I don’t see any obviously bad solder joints, but I’ll take a closer look as soon as I find my magnifying glass, and I’ll let you know if I find anything.
I was planning to get an FTDI cable to play with the software, but I don’t have it yet, nor do I have an ISP. I do have a multimeter, if there’s anything else I can check.
