Questions about service and repair of Siemens TP1200 Comfort
Partial touch loss indicates physical damage to the resistive overlay (film crack, wear). Damage to the touch controller usually causes a complete lack of response. Repair is possible in both cases.
Yes — we archive the project from internal memory or SD card. If Flash is damaged, we ask the customer for a backup from the TIA Portal environment. The project comes back with the panel.
Yes — we service both the standard TP1200 Comfort and the TP1200 Comfort Plus with a capacitive multi-touch screen. Diagnostics will distinguish damage from incorrect configuration.
Diagnostics: up to 5 business days. Repair after approval: 5–7 business days. For 12" display matrix replacement, the time depends on component availability — for standard variants we have them in stock. As a rule — repair time may be significantly extended depending on component availability and repair complexity. Deadlines are agreed individually with the client.
We return the device; if repair is declined, we charge a diagnostics fee (300 PLN net). We can also advise on purchasing a used replacement or a new panel of the same series.

Siemens TP1200 Comfort Panel Repair — 12-Inch Industrial Touchscreen
The Siemens SIMATIC TP1200 Comfort is a premium 12-inch widescreen HMI panel offering high-resolution display, multi-touch capability (2nd generation), PROFINET with 2-port switch, MPI/PROFIBUS interface, and extensive WinCC Comfort Runtime functionality. It serves as a versatile operator interface for complex visualization and control applications. The Comfort Panel premium features — including scripting, PDF/CSV export, VNC, SMTP, and OPC UA — make it a significant automation investment worth protecting through professional repair.
Common TP1200 Comfort failures include LCD backlight degradation, touchscreen controller issues (particularly in humid environments), PROFINET switch port failures, MPI/PROFIBUS interface damage, power supply section degradation, USB and SD card interface malfunctions, and internal flash storage corruption. The dual PROFINET ports with integrated switch add electronic complexity that can develop port-specific communication failures.
EFIXLAB provides TP1200 Comfort component-level repair. Our service covers LCD and backlight module repair, touchscreen controller diagnostics and replacement, PROFINET switch IC repair, MPI/PROFIBUS transceiver replacement, power regulation circuit repair, and storage media recovery. We test all repaired panels with S7 PLC communication, verify both PROFINET ports independently, and perform multi-touch accuracy testing.
TP1200 Comfort repair saves 40–60% versus new panel purchase — meaningful savings given the premium pricing of Comfort Panels. Repair preserves the existing WinCC Comfort project and avoids reconfiguration. All TP1200 repairs include comprehensive testing and our 12-month warranty.
