HMI and Operator Panel Repair
When an operator panel fails, the machine becomes unusable even if it still runs. For a dark screen, a touch glass that no longer responds, worn membrane keys or a panel that will not boot, we repair or renew the faulty part instead of replacing the whole panel.
Repair scope
- Touch glass (touch panel) replacement
- LCD and backlight (CCFL / LED) faults
- Membrane keypad renewal
- Main board and power board repair
- Boot, software and memory card related faults
- Communication port faults
Typical symptoms
- Screen is dark but the image is faintly visible (backlight)
- Touch is registered in the wrong place or not at all
- Panel hangs on the boot screen
- Keys do not respond or the membrane is torn
- No communication with the PLC

Frequently asked questions
Will the project in the panel be erased?
We take care to preserve the existing project during repair. Even so, back up the panel project if possible or make sure you have the project file.
Can I buy just the touch glass?
Yes. We supply touch glass and membrane keypads matching your model code separately.
How long does a repair take?
We do a same-day free pre-analysis; after approval most boards are repaired within 2–5 business days, tested under load and delivered.
What does the warranty cover?
We provide a 6-month warranty on all repaired boards after 100% functional testing under load.
Is the pre-analysis paid?
No. Pre-analysis and fault diagnosis are free; the repair decision is entirely yours.

Send the fault description and a photo of the board if available; we will reply with a free same-day pre-analysis.
