Hi thanks for responding to this thread! I would appreciate all the help I can get!
I have tried wiggling both connectors and I even disconnected the J6 connector to see if anything looked suspicious and reseated it and still the row won't light.
I've looked at wires underneath the playfield following the red/green wire to all of the sockets and nothing looked broken.
I took Grumpy's advice earlier in the thread and tried to figure out which diodes/resistors/transistors went to row 5. I know Q84 is connected and I it looked to me like D12 and D13 were also. I did some DMM testing on those parts in circuit (which I am still learning and didn't test anything yet out of circuit because I have never soldered anything before) and D12 was the only part that produced suspicious readings. With the black lead on the stripe side all of the diodes were testing 0.596, but D12 was testing 2.4. I understand from doing a lot of reading, you tube videos and other threads that testing in circuit isn't reliable, but they were all (diodes, resistors, transistors) producing similar results except that diode so I figured I would start there unless you have some other advice or things to test.
