Our Story: From S9 Repairs to a Full Workshop

We’ve been repairing miners since 2019, starting with the classic Antminer S9 generation. Back then, the goal was simple: keep our own mining farm running reliably. That hands-on experience taught us the hard truths of ASIC hardware: real failures don’t care about forum advice, and “quick fixes” don’t survive load testing.

As the industry grew and the hardware evolved, the repair workload grew with it. By 2023, demand became consistent and large enough that we officially registered the company and built a structured repair operation: intake workflow, documentation, repeatable diagnostics, and proper testing before shipment. In other words, we turned what started as an internal technical capability into a professional repair service that customers can rely on.

Founder

The shop was founded by Aleksandr Muranov, an engineer and miner who started repairs out of necessity long before it became a public service. Since 2019, the work began with keeping his own hardware stable and profitable. That’s the toughest “customer” you can have, because you can’t hide results from yourself: if a repair doesn’t survive real load, you pay for it immediately.

That original standard never changed. Even as the shop grew into a registered company in 2023, we kept the same mindset: we treat every board and every miner like it’s our own. Our approach is built around monitoring, stability, and predictable maintenance, so fixes are made to last, not just to boot.

Better than “for yourself” is hard to beat, and we don’t try to beat it. We just keep doing it.

We are not affiliated with Bitmain and do not perform manufacturer warranty repairs. We provide warranty coverage only for our own repair work.

  • 4–5 business days turnaround for most repairs (standard service across the site)
  • True board-level diagnostics to find the root cause, not just symptoms
  • Full load testing before return shipment

What We Repair

Hashboard Repair

  • Missing hashboard / board not detected
  • Low or unstable hash rate, frequent drops
  • ASIC chip chain failures and related signal issues
  • Power rail problems, shorts, and stability faults
  • Temperature sensor and thermal-related instability

Control Board Repair

  • Boot issues, network/Ethernet problems, connection instability
  • Firmware recovery and flashing when applicable
  • Communication issues between control board and hashboards

PSU Repair

  • No power, voltage instability, shutdowns under load
  • Protection triggers and power delivery faults

Hydro System Service

  • Cooling loop issues affecting stability and temperatures
  • Flow/ΔT related faults and performance instability
  • Inspection and maintenance support for hydro-cooled units

Chip replacement is performed when diagnostics confirm a failed chip is the root cause. In many cases it’s included in the labor pricing, and the exact scope is always described on the specific service page for that board/model. ⚡

How Our Repair Process Works

  1. Intake & documentation: we identify the model/boards and record condition.
  2. Board-level diagnostics: we isolate the failure across power, signals, sensors, and chip chains.
  3. Repair & rework: component-level repair and chip replacement when required.
  4. Verification: stability checks to catch intermittent problems.
  5. Full load testing: boards are tested under real load before return shipment.
  6. Return shipment: packed properly and shipped with tracking.

Rush / Priority Service
