If you are beeping for shorts, always remember how that works.
Most multimeters i have seen yet, beep upon a resistance of 1K or lower.
This means that beeping is more like detecting low resistance than really looking for shorts.
A low resistance could mean a short / defect, but could also mean it's designed that way.
So beeping will give you some idea as to where to look for a short, but will require you to do some closer investigation as to whether you just found a short, or a feature.
You can do this by checking the resistance, eventually taking one side of the component out of the board so you are sure other components have no influence to your test.
Beeping / diode testing probably gives you a reading (millivoltage) on your display, which depends of the type of diode you are testing .
You cannot make any consequenses out of your test if you don't know what the result with that specific part is supposed to be.
So you could ask here what results to expect, stating the exact component type you will be testing.
Or look it up in the component's datasheet.
