Need help with faulty hashboards in Australia

Hey guys, just signed up here after searching around online for days. I’ve seen a lot of talk about miners in the US and Europe, but what about us in Australia? So, I’ve got a couple of issues. I need to get my two hashboards fixed or maybe buy new ones for my S17+ miner. I’ve only been mining for about a month, and right now, I also have an L3++ and a mini doge. My S17+ still runs with one board, but the other one only works for like 5 minutes before throwing an error. I’d love to share some pics of my setup, but I can’t figure out how to upload them here. Anyone got tips?
