ASIC Repair FAQ & Troubleshooting

ASIC Miner Repair & Troubleshooting Knowledge Base

At Jackson Electronic Repairs, we specialize in high-level ASIC miner repair and component-level micro-soldering. Below are answers to the most common hashboard issues we see on the bench.

Why is my Antminer showing “0 ASICs detected”?

The “0 ASICs detected” error in your kernel log is one of the most common issues indicating a total domain failure on a hashboard. This usually means the power delivery has failed somewhere in the chain. This is often caused by a blown LDO (Low-Dropout Regulator), a damaged trace, or EEPROM corruption. Our expert ASIC repair process involves isolating the exact failed component using specialized multi-meters and replacing the dead LDOs or ASIC chips under a microscope, rather than requiring you to buy a whole new board.

Can you repair aluminum-backed hashboards (S21, L9, KS5)?

Yes. Aluminum hashboards require massive amounts of heat to work on, making them impossible for amateur repairmen. We utilize specialized high-mass thermal preheaters to safely service high-density S21 and L9 boards. This allows us to perform precise ASIC chip replacements without warping or destroying the PCB.

What if my miner has water damage or immersion fluid on it?

If your hardware is covered in dielectric fluid, mineral oil, or has environmental corrosion, standard brushing will not work. We offer professional Ultrasonic Cleaning & Repasting. We use a specialized Branson EC Electronic Solution in our ultrasonic baths that completely strips away oil and carbon buildup, while simultaneously coating the board in a protective corrosion inhibitor.

Is it better to replace or repair a hashboard?

In almost all cases, component-level hashboard repair is significantly cheaper than buying a replacement board on the secondary market. A failed hashboard often only has one or two bad ASIC chips or a single blown resistor. Our micro-soldering and chip-level restoration allows us to fix the exact point of failure, saving you hundreds of dollars per unit.

Do you offer ASIC firmware flashing?

Yes. We offer firmware restoration and flashing for units with corrupted control boards. If your control board is bricked, stuck in a boot loop, or refusing to take new over-the-air updates, we can manually re-flash the EEPROM to restore functionality.
