HMI Repair & Industrial PC Repair Services

When an HMI or Industrial PC stops working, your entire machine becomes blind operators can’t monitor, control, or interact with the system. Production slows. Decisions stall. Downtime becomes expensive.

At Epoch Technical, as an ISO 9001:2015 certified company, we specialize in HMI repair and Industrial PC repair for automation and industrial environments. Whether its a non-responsive touch panel or a failed embedded PC motherboard, we focus on repairing your existing unit instead of pushing you toward replacements that take weeks to arrive.

In most cases, repair costs are 60–70% less than buying a new device.

Professional Repair for HMI Touch Displays & Industrial PCs

Every repair is handled in our static-protected electronics lab.

We work down to component level identifying failure sources such as:

Faulty TFT/IPS LCD screens
Cracked or unresponsive resistive/capacitive touch layers
Damaged LVDS ribbons and display backlight inverters
Burnt power supply circuits
Firmware corruption and boot-loop issues
IPC motherboard component failure (CPU VRM / MOSFET / capacitors)

We don’t just replace boards we repair the exact point of failure.

What Our Service Covers

We service a wide range of display and control hardware, including:

HMI touch panels (Touchscreen operator interfaces)
Industrial PCs (IPC repair & refurbishment)
Control display modules and graphical terminals
Embedded panel PCs with Windows/Linux OS
PLC-integrated HMI workstations
Rugged industrial monitors and touch screens

Whether the device is dead, flickering, frozen, or showing distorted graphics we can restore it.
