What are some troubleshooting procedures
1.) First check the power supply voltage
2.) Check the V+ on IC chips to check if the IC chip is getting power
3.) Check every input and output for each stage of a transistor or IC op amp of the circuit until you find no signal
4.) Can you add any others on the list
A SHORT Will make the circuit have no signal in that stage of the circuit, it will have zero voltage on the PCB board pads in that area of the short, Blocking the path to the next stage of the circuit
An OPEN will make a circuit have no signal in that stage of the circuit, breaking the path to the next stage of the circuit
An OPEN of a component in a circuit can also change the bias or gain of the circuit
If a transistor is shorted internally From either Base, emitter, collector it will change what?
it changes the voltage measurements
If the transistor is open it breaks the path from input to output of that stage so the signal is gone
