HMI Repair FAQs
What types of HMIs do you repair?
We repair all major HMI brands including Allen-Bradley PanelView, Siemens SIMATIC, Pro-face GP Series, Schneider Electric Magelis, Omron NS/NT Series, Mitsubishi GOT, Beijer Electronics, Red Lion, Weintek, and more. Our technicians have experience with both legacy and current HMI models.
How long does HMI repair take?
Standard HMI repairs are typically completed within 5-10 business days. Rush and emergency service may be available for critical production situations. Turnaround time depends on the complexity of the repair and parts availability.
Do you offer a warranty on HMI repairs?
Yes, all HMI repairs managed by NJT Automation include a 1-year full-function warranty covering repair-related failures under normal operating conditions.
What HMI problems can you fix?
We handle all common HMI issues including touchscreen failures, LCD/display problems, backlight failures, communication errors, power supply issues, memory and firmware problems, cracked screens, unresponsive buttons, and board-level component failures.
Can you recover my HMI program and data?
We backup, restore, and reprogram HMIs when possible. Include memory cards or a copy of your program if required. We recommend maintaining backups of all HMI applications before sending units for repair.
How much does HMI repair cost?
Most HMI repairs fall between $450-$2,800 depending on model and failure type. We confirm the final price after evaluation before proceeding. You'll never be charged without approval. Repair is typically 50-70% less than replacement cost.
Do you repair obsolete and discontinued HMIs?
Yes, we specialize in repairing legacy and discontinued HMI models that manufacturers no longer support. This includes older PanelView, Pro-face, and Siemens HMI systems that are still in production use.
Is HMI repair better than replacement?
For many industrial HMIs, repair often costs 50-70% less than replacement and can preserve your existing configuration, which avoids reprogramming. Repair is especially useful for obsolete HMIs where a replacement would force an upgrade.
Do you buy broken parts?
Yes. We actively purchase non-working and known-faulty industrial automation equipment. In fact, we often prefer acquiring units with known faults because they can be fully diagnosed, repaired, refurbished, and thoroughly tested before being added to our inventory. This process typically produces a more reliable product than a simply used unit, giving customers greater confidence in the replacement they receive.
