About this model
The Antminer S19j Pro is a widely deployed ASIC miner from Bitmain's S19 series, delivering 104 TH/s. It runs on the same 7nm BM1397 chip as the rest of the series but features a slightly different hashboard layout. Power consumption is 3068W, achieving 29.5 J/TH efficiency.
This model is frequently brought in with chip degradation issues after 2–3 years of continuous operation. The S19j Pro is notably sensitive to power quality and voltage fluctuations. We perform component-level repair: chip replacement, trace restoration, VRM circuit repair, processor and NAND memory replacement, firmware flashing and recovery for control boards.
Don't write off the machine because of one faulty board — repair is often more cost-effective than buying new. Bring it in for diagnostics — we'll identify the problem and provide a quote.
Common issues
Hashrate drops to 70–80 TH/s instead of factory 104 — chip group degradation or single domain failure on hashboard
Unit starts but one board shows ASIC errors — burned LDO regulator or power supply break on hashboard
Elevated temperature with normal airflow — dried thermal paste between chips and heatsink
Red indicator flashing on control board — firmware crash or NAND chip failure
PSU delivering low voltage — electrolytic capacitor degradation after 2+ years of operation
