Identifying failures in a circuit is crucial for troubleshooting and maintaining electrical systems. Here are some steps and methods to help you diagnose circuit failures effectively.
please respect: The electricity safety rules
0. Write a Documentation
take paper and make notes about everything you changed and checked

for following steps, this prevent wrong measurements, useless parts changes
1. Visual Inspection
Check for Obvious Damage: Look for burnt components, broken wires, or signs of overheating, broken or bend IC pins
Inspect Connections: Ensure all connections are secure and free from corrosion.
Inspect Traces - sometimes people cut accidentally traces, by cutting resistor pins
for new builds: look under all IC sockets for pieces from cutter resistor legs for example
Make sure your cables are really connected - I have seen few times wrong pressed Molex pins for example
