Neck board wire voltages:
HC6 (Red): 0.075v
HC2 (Orange): 5.74v

@bibilit, I checked the neckbeard connections and they looked fine. I reflowed all the large connections on the neck board anyway. Then I checked connectivity from the AB to the neck board for all wires. No problems. Retested and no change.
While running, checked the voltages on the seven...
Thank you for the help! I will check the wires going to the neck board as well as the neck board itself. Are there documented voltages on the neck board or those wires I can check?
For clarification:
All caps on analog and LB were replaced. Some were leaking.
I cleaned the logic board vis IPA scrub, then soak in hot water and soap, then scrub then soak in ipa and then toothbrush scrub
Verified there is no high voltage via audio spectrum analyzer, and also no static when...
