We repair Siemens SIMATIC HMI units that were experiencing display malfunction, touch response issues, and intermittent power failure. During testing, faulty display driver ICs, touch controller problems, and power circuit faults were identified. These issues caused unstable operation during machine use. Our engineers carried out micro-level repairs and replaced defective components. After calibration and functional testing, the HMI operated reliably. The repaired unit is now suitable for industrial use.

Note: We are not manufacturers; we only repair.
