MENSCH-MASCHINE-SCHNITTSTELLE • HERSTELLERNEUTRAL • PRÄZISE
HMI panels are the central interface between humans and machines. Service technicians, plant operators, and maintenance personnel use them to operate production equipment, monitor process values, detect malfunctions, and intervene in machine processes. If an HMI panel is defective, the touchscreen is unresponsive, or the display remains black, machine operation can be severely restricted. In the worst-case scenario, a defective control panel can lead to a production outage. Retrofit GmbH supports industrial companies worldwide with HMI panel repair, technical fault analysis, maintenance, replacement, and procurement of HMI operator panels, industrial panels, and touch panels. Our goal is to reduce downtime, keep existing machines operational, and avoid costly new purchases whenever possible.
Maximum performance, minimum downtime
A defective industrial PC or HMI panel doesn’t automatically mean a new operator panel or visualization solution is needed. Especially with older machines, HMI panels are often closely integrated with the PLC control, machine visualization, existing software, and communication interfaces. Replacing them with a new device can create additional work and lead to extended downtime. Repairing an existing HMI panel instead of buying a new one can help preserve existing user interfaces and allow the system to continue operating without a major overhaul.
Fast exchange, maximum security
A professional HMI panel fault analysis helps to technically assess the defect. It’s not always immediately clear whether the cause lies with the display, touchscreen, power supply, control board, software, interface, or a connected PLC component. Our manufacturer-independent service allows us to precisely pinpoint the root cause of the fault in conjunction with the automation technology of your entire system.
Touchscreen repair HMI, replacement of defective touch films, calibration and glass repair of HMI panels in case of mechanical breaks.
Display repair HMI for flickering, streaky or black screens, as well as backlight repair HMI for defective backlighting.
Image backup of HMI panel, software testing of HMI, and diagnostics for errors such as "HMI does not connect to PLC".
Many machines operate reliably for extended periods. Often, the system is fundamentally functional, but individual operating devices, displays, or touchscreens fail. Especially with older systems, HMI panel repair can be an economical solution, as a complete retrofit incurs high costs.
Changes to installation cutouts, new wiring, new software licenses, or a complete overhaul of the operating logic can lead to extended production downtimes. HMI panel repair helps preserve the existing machine visualization and get it back up and running more quickly.
A structured process ensures that your defective industrial motor is quickly, professionally and manufacturer-neutrally tested and repaired to minimize downtime.
SUBMIT AN INQUIRY
You send us information about the HMI panel (nameplate, photos, error messages) and details about the connection to the PLC.
INITIAL ESTIMATE
Based on your information, we will check whether sending the item in, a repair assessment, a spare parts search or an exchange solution is appropriate.
DIAGNOSE PANEL
The control unit is examined in the laboratory. The display, touchscreen, backlight, power supply, control board, interfaces and software are analyzed.
COMPONENT REPLACEMENT & REPAIR
The process includes professional repair, component replacement of the HMI panel, and a final functional and final test.
Key information at a glance
Unter Reparatur HMI Panel versteht man die technische Prüfung, Fehleranalyse und Instandsetzung eines industriellen Bedienpanels. Dazu können Touchscreen, Display, Hintergrundbeleuchtung, Frontglas, Netzteil, Steuerplatine, Software und Schnittstellen gehören.
Eine HMI Panel Reparatur lohnt sich häufig, wenn das Bediengerät Teil einer bestehenden Anlage ist, ein Ersatzgerät schwer verfügbar ist oder eine Umrüstung hohe Kosten verursachen würde. Besonders bei älteren Maschinen kann die Reparatur sinnvoll sein.
If an HMI isn’t displaying an image, the display, backlight, power supply, control board, or software could be the problem. A technical diagnosis will help narrow down the cause.
Depending on the device and the extent of the damage , touchscreen repair (HMI) , replacement of the touch film, or calibration may be possible. Whether this is advisable must be assessed on a case-by-case basis.
During an HMI backlight repair , the display’s backlight is checked and, if possible, repaired or replaced. This is relevant if the display is very dark or barely visible.
Depending on the design and availability of spare parts, the front glass, touch film or user interface can be checked and replaced if necessary.
If an HMI fails to connect to the PLC, the cause could lie in the HMI, the PLC, the cable, the interface, the network, or the software. Retrofit GmbH provides support with the technical evaluation.
Data backup, image backup, or image backup may be possible depending on the device and its condition. Preserving existing visualizations and configurations is particularly important for older systems.
Retrofit GmbH operates independently of manufacturers. The focus is on finding the technically and economically suitable solution for your system.
If a repair is not possible or not economical, retrofit GmbH provides support with HMI panel exchange service, HMI panel spare parts service, or the search for a suitable replacement solution.
