    • Work carried out in the workshop or at a manufacturer-approved centre.
    • Functional test (burn-in) before reshipping.

FAQ

Is my device still under warranty?

The duration depends on the manufacturer and the purchase date. Have your invoice and serial number ready, then open a request using the form at the bottom of the page.

What if the fault is not covered?

We issue a detailed quote (parts, labour, logistics). You decide whether or not to accept it.

Can I send just the hashboard / PSU?

Yes, if support tells you to. Follow the packaging instructions exactly and state the RMA number.

Will I lose my settings?

A reset may be necessary. Back up your configuration (pools, IP) before shipping.
