Quick answer

No dashboard, no IP, no response usually means the control board never finished booting — corrupt storage, a bad firmware image, or a hung controller.

This is almost always a control-board / firmware issue, and often recoverable with a re-flash.

Full diagnostic flow

Does the miner get an IP address (check your router/DHCP table)?
  • No IP at all → Try a different cable and switch port, and check the control-board LEDs. Any link/activity?
  • Has an IP but web UI won't load → The OS booted but the mining/web service is hung. Power-cycle; if it recurs, the controller storage may be failing — re-flash it. [Fix it yourself] Error-code guide →
Try a different cable and switch port, and check the control-board LEDs. Any link/activity?
  • Still no link/no LEDs → Re-flash the controller with the correct firmware via SD card (or recovery). Does it boot?
  • Link comes up on another port → It was a cable/port/DHCP issue, not the miner. Use a known-good port and a static IP if your DHCP pool is full. [Fix it yourself] Error-code guide →
Re-flash the controller with the correct firmware via SD card (or recovery). Does it boot?
  • Boots after re-flash → It was corrupt firmware / storage. Keep a known-good image on hand. If corruption returns quickly, the SD/eMMC is failing and should be replaced. [DIY with care] Error-code guide →
  • Still dead after re-flash → Hardware control-board fault (failed eMMC, PMIC, or Ethernet PHY). Swap a known-good control board of the same generation, or send it in. [Advanced DIY] Error-code guide →

This points at board-level damage. You can attempt it, but the realistic call for most owners is to send it to a repair bench.

Fix it yourself

Work the matching symptom decision tree and error-code guide step by step. Most cable, cooling, network and firmware faults are solvable on the bench you already own.
