Repairing the original device

Our first step is to assess whether the original panel, monitor or keyboard can be repaired at component level. This reduces the risk of compatibility, interface and machine configuration problems. Work involving memory, settings or software is assessed individually for the particular model and depends on the availability of a backup.

Service in the Netherlands for European customers

Our service workshop is located in Helmond, the Netherlands. After receiving the device, we diagnose it, assess the repair options and provide a quotation.

We accept business shipments from the Netherlands, Belgium and other European Union countries.
