Repair HMI
and Operator Panels
Siemens SIMATIC · Allen-Bradley PanelView · Mitsubishi GOT · Schneider Magelis · Weintek
A black screen or unresponsive touch means the operator cannot control the machine. We repair display matrices, touchscreens and main boards of HMI panels from all manufacturers. The visualization project remains untouched. 12-month warranty.

Comprehensive service of HMI and operator panels from all manufacturers
LCD / TFT display matrix
Replacement of LCD/TFT display matrix — mechanical cracks, dead pixels, smears, uneven backlight. Color and brightness calibration after replacement.
Backlight
Replacement of CCFL inverter or LED module. Restoration of full screen brightness and correct contrast.
Touchscreen
Replacement of resistive (4W, 5W) and capacitive (PCAP) touch panels. Calibration after replacement.
Mainboard and electronics
Repair of CPU/SoC, RAM and Flash memory, DC/DC power supplies, LCD/LVDS controllers, USB/Ethernet ports.
Membrane keyboards
Regeneration and replacement of membrane keyboard foils for Key Panels (KP). Repair of function and navigation buttons.
EOL and legacy panels
We repair discontinued panels: SIMATIC MP277, PanelView 5/550/600, GOT1000, Magelis XBTN — models without manufacturer support.
Why EFIXLAB?
HMI repair instead of buying new — faster, cheaper, without reconfiguration
- 30–70% savings — HMI panel repair cost is a fraction of a new panel price, especially for older models.
- Visualization project untouched — we repair hardware without interfering with the HMI project. No reprogramming needed.
- Faster than a new panel — repair: 3–7 days, delivery of a new panel: weeks. For a stopped machine this is an enormous difference.
- Service of EOL panels — we repair discontinued models for which new devices are unavailable or very expensive.
- Replacement of only the damaged component — precise diagnostics identifies the exact cause, we do not replace everything if unnecessary.
- 12-month warranty — on every repair performed, without exceptions.

Report HMI panel fault — no-obligation quote
Provide the panel model and fault description (black screen, touch not working, crack). An EFIXLAB specialist will contact you with a diagnosis.
Dziękujemy! We have received your request — our HMI specialist will contact you shortly.Frequently asked questions
Yes — we repair Siemens SIMATIC, Allen-Bradley PanelView, Mitsubishi GOT, Schneider Magelis, Weintek, Pro-face, Beijer panels and many others. If in doubt about a specific model, contact us before shipping.
Yes — we repair the panel hardware, we do not interfere with the software and visualization project. The project file remains intact. If the panel Flash memory is damaged, we inform you before repair.
A black screen can be caused by backlight failure (most commonly), a damaged display matrix or main board failure. Diagnostics identifies the specific component, so we replace only what is damaged.
Yes — we specialize in older models: SIMATIC MP277/370, PanelView 5/550/600, GOT1000, Magelis XBTN. We have components for regeneration or can find compatible replacements.
The price depends on the model and type of fault. Diagnostics is charged — the cost is included in the repair price — after which you receive an exact quote. Repair is usually 30–70% cheaper than a new panel.

HMI Panel Repair — All Manufacturers and Technologies
Human-Machine Interface (HMI) panels from manufacturers including Siemens, Allen-Bradley, Mitsubishi, Beijer, Weintek, Pro-face, and others serve as the operator window into industrial processes. From simple text displays to large multi-touch panels running SCADA visualization, HMI panels handle process monitoring, alarm management, recipe control, and data logging. When an HMI panel fails, operators lose visibility and control — often requiring machine shutdown for safety reasons.
The most common HMI panel failures span several categories: display issues (LCD backlight degradation, LED driver failure, LCD panel aging with dead pixels or color shift), touchscreen problems (resistive film wear, capacitive sensor failure, controller IC faults), mainboard electronics (processor failures, memory corruption, power supply degradation), and communication faults (Ethernet PHY damage, serial port failures, fieldbus interface issues). Environmental factors — UV exposure, cleaning chemicals, operator finger pressure, and temperature — accelerate panel aging.
EFIXLAB provides comprehensive HMI panel repair regardless of manufacturer. Our service covers the full range of panel repairs: LCD backlight conversion and repair (including CCFL to LED upgrade), touchscreen digitizer replacement and calibration, mainboard component-level repair (power regulation, processor, memory, communication ICs), and storage media recovery. We stock common LCD panels, touchscreen digitizers, and electronic components for rapid turnaround across major HMI brands.
HMI panel repair typically saves 35–65% versus new panel purchase — with savings increasing for larger panel sizes. For discontinued models, repair avoids the cost and effort of HMI application redevelopment on a new platform. We test every repaired panel with extended burn-in, touch calibration verification, and communication protocol testing. All HMI panel repairs carry our 12-month warranty covering display, touch, electronics, and workmanship.
