Problem with two lights not working; one stays on, while the other doesn’t turn on. I replaced the sockets and it didn’t help. Thanks.

Definitely on the lamp board. I swapped out the board with a working board and the issue resolved. Perhaps a diode?
I meant the aux lamp board. My bad.
Quoted from mskoenen:What do you mean when you say "they don't go to the lamp board"? The 12 target light is at pin 4 on J3 of the lamp driver board and the 14 target light is at pin 6 of J1 on the lamp driver board.
I'd first test continuity between those pins and the wires at the socket.

I tested continuity and they tone out to the board so the issue is definitely on the board. I also swapped it out with a working board and had no more issues.
