Fix the defect and bring evidence of the repair with you. Explain your financial situation to the Judge. If he or she is compassionate, they may waive the fine or impose the minimum. Sometimes court costs cannot be waived. In any event, you can always request "time to pay"
due to your hardship and the court may give you several months to come up with the money.
I don't know how the practice is in Johnson City but if you show proof of fixing the equipment failure, the fine, if any should be minimal.

Some court drop tickets if you repair the defect. If the court won't do that your option is to take a plea and pay the fine or go to trial and pay a higher fine if convicted. Perhaps the court will let you do community service but I've never heard of that for a moving violation.
