HMI Repair

Human Machine Interfaces (HMIs) are critical components of modern industrial settings as they link operators with control systems like PLCs and drives. If an HMI fails, it doesn't just mean one screen isn't working—production monitoring, alarms, data logging, and plant efficiency in general get impacted. At Epoch Technical, we offer expert HMI repair services that are intended to bring operator panels and touchscreen systems back to optimum performance while keeping downtime to a minimum.

Our engineers and technicians address an array of HMI problems, ranging from unresponsive or cracked touchscreens to faded or blank LCD/TFT screens, failed backlights, power supply malfunctions, and PLC communication issues. We also diagnose software bugs, firmware corruption, and input/output faults that can hinder HMIs from functioning as they should. Rather than expensive replacements, our solution relies on component-level repairs to ensure long-term reliability and substantial cost savings for our customers.

We accommodate both basic and high-end HMI panels, such as models with integrated Ethernet, Profibus, Modbus, and other communication standards. Our repair procedure involves extensive diagnostics, circuit-level examination, replacement of faulty components, touch panel calibration, and testing under load conditions. This guarantees that repaired HMIs are to OEM specifications and can be easily re-integrated into your industrial control system.

Epoch Technical partners with top-of-the-line brands including Siemens, Allen-Bradley, Schneider Electric, Omron, ABB, and Mitsubishi. Our expertise spans industries including food and beverages, pharmaceuticals, oil and gas, metals, marine, and water treatment where seamless HMIs are essential for easy flow of operations.

Whether it is an older legacy HMI panel or a newer touchscreen terminal, our HMI repair services are engineered to deliver quick turnaround, technical precision, and optimal equipment availability. Through repair versus replacement, you extend equipment life, lower capital outlay, and get your plant back online without the expense of downtime.
