I am getting no reading on terminal 10 and center pin. I have attached pictures. I did remove a bit of solder from #10 before I took the pic to make sure I didn't have too much solder. Any help would be appreciated.
Could you post pictures of the wiring on the headphone jack? No resistance reading at terminal 10 would have me thinking that one of the black wires on the headphone jack isn't well captured by solder.
Which center pin? You would need to say something like:
"The center pin of the (left RCA jack, right RCA jack, 9 pin socket, or other) is supposed to read (insert reading from manual) but instead I see (post your reading).
