We repair Exter T100 HMI that had a dead display and unresponsive keys. Circuit testing revealed defective driver ICs, faulty capacitors, and regulator problems. These faults prevented the HMI from operating correctly in its system. We carried out micro-level repairs and replaced damaged components. The HMI was then tested in multiple cycles for performance verification. After repair, the unit worked reliably with stable operation.
Note: We are not manufacturers, we only repair.
