Measure J5 pin 8 to Ground, should measure 4.5k. If not then check R7 (1.5k) and R8 (3k) for anything missing or a damaged trace.

Measure J5 pin 8 to U1 pin 78, should measure 1.5k. If not look for damaged trace.

Measure J5 pin 10 to U1 pin 10, should measure 0 ohms. If not look for damaged trace.

Measure J5 pin 12 to U1 pin 11, should measure 0 ohms. If not look for damaged trace.


If all of the above checks good, then suspect U1 has an issue.
Screwing up is one of the best learning tools, so long as the only thing you're not learning is how to screw up.
