About Aleksandr

I started working hands-on with ASIC miners in 2019 (my first units were S9 and S17+). Before ASIC repair became my primary focus, I ran an engineering business servicing commercial utility infrastructure (water, gas, heating, and wastewater). After relocating to the United States, ASIC repair became the core of my work and the foundation of Antminer Repair LLC.

What I Work On

  • Hashboard repair and chip-level fault recovery, including stability issues and intermittent failures.
  • Firmware setup and performance optimization focused on safe tuning and stability-first operation.
  • Hydro diagnostics and maintenance workflows where cooling behavior impacts reliability and uptime.

How We Approach Quality

I treat every board like it’s my own hardware: careful diagnostics, precise repair work, and verification before anything is considered ready. Our team also includes an electronics repair specialist with a background in microelectronics service and PCB engineering, which helps maintain consistent results on complex cases.

Some workshop methods used for protection and stability improvements are proprietary. We share the principles and verification approach, but we do not publish sensitive implementation details.

How Our Technical Content Is Created

  • We study recurring technical questions from real customers and common industry discussions.
  • Topics are formed around practical repair cases and repeatable diagnostic patterns.
  • Articles are reviewed and edited by Aleksandr Muranov for technical accuracy and real-world relevance.

Verification Standards

Repairs are verified through structured testing, including bench validation and in-miner testing. In-miner verification is run for a minimum of one hour under elevated operating modes, and longer when the platform or failure mode requires it. Typical turnaround for most repairs is 4–5 business days; rare or unusual faults can take longer depending on diagnostics complexity and parts availability.

If you need diagnostics or repair service, contact our repair team and get your miner back to full power. ⚡
