It might sound cold, but The court does not care about any extenuating circumstances that prevented you from paying your fines off. Don't know about AZ, but we won't lock you up for failure to pay fines. We will extend your probation. We have taken bond money for the fine. We have credited time considered served before. We have converted the remaining fines to community service.

The grand scheme of things is that nobody put you in this situation but yourself. The court looks at it that way though. It may not be the end of the road for you. You have an outstanding debt that you agreed to pay. Maybe if you are lucky, they'll term you with the remaining balance. Or maybe they'll term you and send you to collections.
