Human Machine Interfaces are your window into the automation process. When screens fail, crack, or malfunction, your operators lose visibility into critical operations. Flexa Systems specializes in HMI repair, from simple touchscreen replacements to complex motherboard repairs. We service all major brands and can often repair units that others consider unrepairable.

Why Industrial HMI Touch Screens Fail
HMI panels endure constant physical contact, temperature swings, vibration, and electrical noise. Unlike consumer touchscreens, industrial HMIs must function reliably for 10–20 years in harsh environments. When they fail, production stops.
Digitizer & Resistive Layer Wear
High-frequency touch contact degrades the resistive layers in older touch panels. Symptoms: unresponsive zones, touch drift, phantom inputs. We replace digitizers with compatible industrial-grade components.
Backlight & LCD Degradation
CCFL and LED backlights dim over time, and LCD panels develop dead pixels, color shifts, or complete failure. We source compatible LCD and backlight assemblies for all major HMI brands.
Power Supply Failures
Internal power supplies on HMI panels fail from capacitor aging and voltage spikes. We perform board-level power supply repair and replace failed capacitors and regulators.
Communication Card Failures
EtherNet/IP, PROFIBUS, and serial communication failures disconnect the HMI from the PLC. We diagnose and repair communication boards and firmware.
Environmental Contamination
Dust, oil mist, and moisture ingress damage internal electronics. We perform full disassembly, cleaning, conformal coating reapplication, and seal restoration.
HMI Repair vs. Replacement Cost Analysis
Replacing an industrial HMI is rarely as simple as ordering a new panel. Modern HMI software must be licensed, panel designs recertified, and operators retrained. For older Siemens TP or Allen Bradley PanelView systems, replacement means a full migration to a current platform — a project costing $10,000–$50,000+.
| Factor | Repair | Replacement |
|---|---|---|
| Cost | 20–50% of new panel price | Full panel + software license |
| Program Preserved | Yes | No — requires migration |
| Lead Time | 3–15 days | 4–16 weeks |
| Operator Retraining | None | Required |
| Panel Certification | Not required | Required for UL/CE panels |
| Legacy Support | Yes — all discontinued models | Limited — OEM may not support migration |
💡 Allen Bradley PanelView Plus 6 and Siemens TP177 panels are discontinued. We repair them — keeping your existing PLC program and operator interface without a costly migration.
