Optocouplers are all inserted and I believe in proper orientation. After looking around I noticed one of the pins on IC2 shift resistor was not connected and after messing with it accidentally ripped one of the pins off. I tried to then remove the soldering and replace it with a new shift resistor, but as I was removing the IC, some of the solder pads came with off the pcb. Needless to say, mistakes were made, as seen in the pictures below. I believe this was the original source of my problems, but now I’ll need to reinstall IC2, without some of the pads. Is it possible to share where specifically the routings are supposed to go for pin 5, 8, and 16. I think I’ll have to end up just using a short wire from the pins to their destinations since I cannot attach them to their original pads.
Next time I’ll be way more careful putting heat directly on the solder pads, considering how easily they come right off. Any help is appreciated!
