(OP)
I have voltage coming into my vfd but nothing coming out and the screen is blank. Is there an internal fuse or is the vfd just bad?

RE: Vfd
What about a speed reference?
What model is it?

Don't know enough about the PF drives to know if that's a separate board or a part of a monolithic board now. If it's the latter, it's hopefully still under warranty because the cost to repair will likely approach or exceed the cost to replace.

Above that hp, you may have some parts of the drive that are serviceable. Larger drives also tend to have internal fuses which often are replaceable.
How about a little more information.
