Things to do

Measure the resistance between the collector and the emitter (Vce). Reverse the probes and measure the resistance again. It should read in the megaohm range for either direction. If not, the transistor is damaged.

Measure the forward and reverse resistance of the base-emitter (Vbe) leads. Do this by placing the red probe on the base and the black probe on the emitter and then reversing. Calculate the reverse to forward ratio. If this is not more than 1000:1, the transistor is damaged.
