Yes — if the panel starts at all, we archive the WinCC project from internal memory or SD card. The project comes back with the panel. If Flash is damaged, we inform in advance and ask the customer for a project backup from TIA Portal/WinCC.
The cost depends on part availability and scope of work. Diagnostics is paid — the cost is included in the repair price, and a detailed quote reaches you within 24h. The total repair cost is typically significantly less than the price of a new panel.
Yes — it is one of our most commonly serviced Siemens panel models. We know its hardware architecture and typical faults well.

Siemens TP700 Comfort Panel Repair — 7-Inch Premium HMI Service
The Siemens TP700 Comfort Panel is a 7-inch widescreen HMI with PROFINET (2-port switch), MPI/PROFIBUS, and WinCC Comfort Runtime — providing premium functionality in a compact form factor. The TP700 Comfort bridges the gap between Basic Panels and larger Comfort Panels, offering scripting, trend archiving, recipe management, and OPC UA connectivity while fitting in smaller machine enclosures. Widely used in machine building and panel applications where 7-inch is the optimal display size.
Common TP700 Comfort failures include touchscreen sensitivity degradation, LCD display issues (backlight dimming, pixel defects), PROFINET port failures, MPI/PROFIBUS interface damage, power supply section faults, and internal storage corruption. The compact panel design concentrates heat, which can accelerate capacitor aging in the power supply section. Exposure to cleaning agents and vibration in production environments contributes to touchscreen and connector degradation.
At EFIXLAB, we repair TP700 Comfort panels at the component level. Our service includes touchscreen digitizer replacement, LCD module repair, PROFINET switch and PHY repair, PROFIBUS transceiver replacement, power supply circuit restoration, and flash memory recovery. Complete testing includes S7 communication verification, touch calibration, and extended thermal burn-in.
TP700 Comfort repair saves 35–55% versus new panel cost. As a Comfort Panel with premium features, the TP700 represents meaningful investment worth protecting through repair. All repairs preserve the existing WinCC project configuration and include comprehensive testing and our 12-month warranty.
