On-Site Antminer S19 Technician

I run a small bitcoin-mining facility in Rosenberg, Texas and several of my Antminer S19 units have gone down. I need someone local to the Sugar Land / Rosenberg area who can drive to the site, pull the bad rigs, and drop in spares so hash-rate loss is kept to a minimum.

After swapping them out you will take the faulty miners back to your own workshop, diagnose the issue, perform board-level repairs, handle any required circuit troubleshooting on power supplies or control boards, and then return fully tested units for re-installation. If you already have the specialized tools, microscopes, hot-air stations, and firmware jig cables great—we can move faster—but I’m happy to discuss supplying anything that is missing.

Success for each batch is simple:
• Dead miner out, spare online at site
• Original unit returned fully functional, passing a 24-hour stability test
• Brief repair log (fault found, parts replaced)

Most visits can be scheduled during daytime hours, though I’m flexible if an evening works better. Let me know your experience with S19 hardware, typical turnaround time, and your availability for the first swap so we can keep these racks humming.
