Since they are ignoring you, file suit against them. Because your claim is under $10,000, you can file this in small claims court without a lawyer. Here's a link to guide you through that process: http://www.lasvegasjusticecourt.us/divisions/small_claims/
Filing the suit will give you the collection options and leverage you need to collect the debt owed you. That's because once the suit is filed and a judgment awarded, you become a judgment creditor, and if the HOA doesn’t then pay the judgment, you can have the sheriff serve a summons on the directors for a debtor examination. That forces the directors to meet you in court again and answer questions under oath about HOA assets. After that information is obtained, you have the power to attach HOA bank accounts and/or place liens on any property the HOA owns to satisfy the judgment. In my experience, simply filing the suit is typically all you need to do to resolve this outside of court because most of the time, once served with a summons one is being sued, the directors will pay your claim to avoid the cost of defending a suit the HOA is sure to lose.
