Default Transistor Fault Checking

Hi,

Any advice on how come when a particular transistor when soldered gives
out different readings as compared to when it has been desoldered and
taken out.

When desoldered and taken out from pcb, gives good readings indicating
the transistor is good. However when on board, it gives inconsistent
readings showing the transistor is bad.

End of day, is the transistor good or bad? Thanks.

Am using analog multimeter under the diode function for checking on
transistors.Thanks.

Good in your hand and bad on the board.
The logic is the board is bad. rite?
