TROUBLESHOOTING
Channels 20-24 all turn on together
RP2 is likely cracked in half or failed. OpAmps could also have failed
Outputs are flickering
C4 is probably failing
No output on normal, but works fine with self-test
DIP switches are probably not set correctly. Be sure DIP switch 3 is down
If DIP switches are correct, possibly a bad DMX chip or DMX opto-isolator
U2 is DMX chip, U22 is opto-isolator. There are no spare internal DMX chips
DMX Status LED is solid on regardless of DMX being plugged in or not
C4 failing. Outputs are also very likely flickering
