I used my volt meter to test the bulbs but the volt meter goes off over the whole tree

Not sure what that mean exactly.

does it have standard miniature lights or LEDs?

One thing to check is that is the plug. It may have fuses in it.

It may also have a fused light which will typically have a different color base (white). Find that bulb in the string and pull it out, that may actually fix the problem. Here is a video that has something about that at about the 6 minute mark.
