GRAFIKONTROL Product Lines We Repair
Our engineers are trained on the full GRAFIKONTROL product range. Below are the major product families we service.
SK series Operator Terminals
Compact graphical operator terminals with 4-10 inch color displays, real-time process monitoring, alarm management, and Ethernet connectivity. Common issues include LCD backlight failure, touchscreen unresponsiveness, connection drops, and memory card corruption affecting recipe data.
GK Process Controllers
Embedded programmable controllers with integrated visualization for standalone operation. Typical failures involve CPU lockups after power fluctuations, Ethernet port failures, analog input calibration drift, and password recovery in plants without backup documentation.
PanelView Advanced HMI Modules
Multi-protocol gateway modules enabling GRAFIKONTROL terminals to communicate with Siemens S7, Allen-Bradley, Schneider, and legacy PLCs. Repair typically involves firmware rewrite, serial port recalibration, protocol stack errors, and gateway communication timeout resolution.
Industrial Monitoring Displays
Large-format 15-22 inch industrial LCD/LED displays for plant floor dashboards and KPI visualization. Common repair work includes contrast failure, dead pixels in LED matrices, HDMI/DVI input failures, and thermal sensor malfunction causing shutdown.
MobileControl Wireless Terminals
Battery-powered operator pendants with Wi-Fi/RF connectivity for mobile machine operation and material handling. Failures typically stem from battery management faults, antenna corrosion, wireless module crashes, and NAND flash wear from frequent updates.

Common GRAFIKONTROL Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in GRAFIKONTROL equipment arriving at our workshop.
- ✓SK Series Display Backlight Failure Dark Screen — GRAFIKONTROL SK terminals use CCFL/LED backlight drivers prone to capacitor aging in high-temperature Indian shop floors (40-50°C). Backlight power supply degradation is accelerated in dusty environments typical of textile mills, cement plants, and chemical factories.
- ✓GK Controller CPU Lockup After Power Transients — GRAFIKONTROL GK series embedded controllers lack robust voltage regulation for Indian grid conditions with 20-30% voltage fluctuations common in manufacturing areas. Power supply tolerance margin (3.3V rail tolerance) is exceeded during brownouts, causing CPU watchdog timeout and firmware crash.
- ✓PanelView Gateway Ethernet Port Silent Failure — GRAFIKONTROL PVM Ethernet modules use industrial PHY chips vulnerable to EMI coupling from nearby variable frequency drives (VFDs) and welding equipment. Crosstalk causes intermittent packet loss, then complete Ethernet MAC failure without hardware error indicators.
- ✓Touchscreen Calibration Drift and Dead Zones — GRAFIKONTROL SK operator terminals experience resistive or capacitive touchscreen calibration loss due to vibration, thermal cycling (-10 to +60°C in uncontrolled plant environments), and contamination from coolant spray or powder residue common in Indian manufacturing.
- ✓NAND Flash Memory Corruption Boot Failure — GRAFIKONTROL MobileControl and GK series store firmware and application code in MLC NAND flash. Repeated power-on-power-off cycles during plant shutdowns, combined with Indian grid frequency jitter, cause wear leveling algorithms to fail. CRC errors prevent OS boot.
- ✓MobileControl Wireless Antenna Corrosion Signal Loss — GRAFIKONTROL wireless terminals used in chemical, food processing, and petrochemical plants are exposed to salt spray, acidic vapors, and humidity cycling. Antenna PCB traces corrode, feed line impedance shifts, and RF module loses coherence, reducing range from 100m to <10m.

Frequently Asked Questions — GRAFIKONTROL Repairs
Do you repair GRAFIKONTROL equipment anywhere in India?+
Yes. Synchronics Electronics repairs the full GRAFIKONTROL product range including SK operator terminals, GK embedded controllers, PanelView gateway modules, industrial displays, and MobileControl wireless pendants. We offer PAN India doorstep pickup and delivery from Mumbai, Delhi, Pune, Bangalore, Hyderabad, Chennai, Ahmedabad, Kolkata, and all industrial cities. All repairs are processed at our headquarters facility in Vadodara, Gujarat, with 24-48 hour turnaround for standard faults.
What is the typical repair time for a GRAFIKONTROL SK operator terminal with display failure?+
Most SK series display and backlight issues are resolved within 2-3 working days. If the fault is isolated to the LCD panel or backlight driver circuit, we can often perform same-day diagnosis and order replacement components. Complex faults involving CPU or Ethernet modules may require 5-7 days for firmware testing and validation. We provide loaner terminals where needed for mission-critical applications.
Does Synchronics repair GRAFIKONTROL equipment if it was not originally supplied by us?+
Absolutely. Synchronics is an independent service center certified to repair all GRAFIKONTROL product families regardless of original supplier or purchase channel. Whether your terminal came from the original German distributor, an Indian system integrator, or was sourced secondhand from another plant, we provide identical repair quality and warranty.
Can you reprogram a GRAFIKONTROL GK controller if we have lost our backup firmware?+
Yes. Synchronics maintains firmware libraries for all major GRAFIKONTROL GK series versions (firmware 1.x through 5.x). If your controller has become corrupted or you lack backups, our engineers can extract the original code from identical units in our test lab or access GRAFIKONTROL firmware repositories through our distributor partnerships. We can also assist in recovering custom application logic if you have source code or system documentation.
What is the warranty on GRAFIKONTROL repairs performed by Synchronics?+
All GRAFIKONTROL repairs carry a minimum 12-month parts and labor warranty. High-criticality equipment (pharmaceutical batch terminals, chemical reactor control) can be extended to 24 months. We also offer extended service contracts covering preventive maintenance, quarterly health checks, and priority emergency response for plants operating 24/7 shifts.
How do I send my GRAFIKONTROL unit for repair?+
Pack the unit securely and courier it to our Vadodara workshop. Include a note with the fault description and your contact details. We will log it into our system and WhatsApp you a job number within 24 hours of receipt. Doorstep pickup is available in Vadodara, Ahmedabad, Surat, Mumbai, and Pune.
What is the cost of repairing a GRAFIKONTROL drive or PLC?+
Repair cost depends on the model and the fault. We offer a free diagnosis — once we identify the fault, we provide a fixed quotation before proceeding. Typical repairs cost 20–40% of the new unit price. We will never repair without your approval.
What warranty do you provide on GRAFIKONTROL repairs?+
All repaired units carry a 6-month comprehensive warranty covering the same fault and related issues. If the fault recurs within the warranty period, we repair it free of cost.
Do you provide a no-fix, no-fee guarantee?+
Yes. If we cannot repair your GRAFIKONTROL unit after diagnosis, you pay only the diagnosis fee (₹500–₹1,500 depending on the product). The unit is returned to you at no additional charge.
