Ray, I have another clue to this issue. If you open up the attached photo, you will see an arrow pointing to one of the pins on the 40-pin IC socket. I don’t see anything wrong with the solder joint. But if I touch this joint with a pick, it starts connecting. I’m not applying any noticeable pressure. I’m just using the pick since my fingers are to large to touch 1 joint at a time. I can try removing and reapplying the solder here. But I’m wondering if it is a bad IC. What do you think?
