Hi,

Please I'd like to know how to make a certain transistor is failed or not? , without putting it in a circuit.

A simple but not conclusive test for BJT is to check for diode function between base and emitter and base and collector using an ohmmeter or DMM with diode test function. Remember to check both directions by reversing the leads of the test meter.

After you have done that, check for high resistance between collector and emitter in both directions.
