HMI Repairs

We saved our customer's money with the repair on this Sinumerik 810D HMI screen.

The backlights had gone short circuit which in turn took out the inverter.

We were able to fully repair with spare parts we keep in stock, meaning a quick turnaround for a fraction of the price of replacement.

We are now able to offer all Siemens spares in both the Sinumerik and Sinamics ranges. All are fully tested and warrantied, and we can even provide a fitting service if required. Please contact us using the red buttons at the top of the page.

Please do call us, even if only for advice. We will always try to help first with advice and remote support. If we cannot help remotely, we will then advise you of the best options and attend the site to resolve them if necessary.

Many companies will request the end user remove servo drives and hardware and send it to them for diagnosis and repair.

Ultimately, the customer ends up with a huge bill and, more often than not, is still left with the same issue unresolved and unfixed.
