Have you tried Advantech's Onsite Service?
Advantech will confirm the visit time with the customer and send a repair engineer to your designated location in the shortest possible time.

Advantech provides you with the option to call for service when needed, or to get a 1, 2, or 3- year coverage plan with a much better service rate. We will arrange for a qualified engineer to bring repair parts the next day, and check the defective unit onsite.
