CONTROL KING Product Lines We Repair
Our engineers are trained on the full CONTROL KING product range. Below are the major product families we service.
CK-3000 Series Programmable Logic Controllers
Modular PLC platform used extensively in textile, chemical, and food processing. Common repairs include input/output module failures, CPU board degradation from humidity and thermal cycling, and communication port faults in harsh mill environments.
CK-Flex Operator Interface Terminals
Industrial touchscreen HMI systems for real-time process monitoring. Frequent issues include LCD backlight failure, resistive touch membrane wear, communication gateway card faults, and firmware corruption from power surges.
CK-Drive Servo Control Modules
Precision motion control for packaging, printing, and material handling lines. Typical failures involve IGBT power stage shorts, encoder feedback signal loss, gate driver IC burnout, and resolver interface card degradation in EMI-heavy environments.
CK-IO Remote Input/Output Modules
Distributed I/O racks for decentralized control in multi-zone production facilities. Common faults include relay contact pitting, analog input isolation barrier breakdown, communication interface card failure, and terminal block corrosion from chemical vapors.
CK-Power Supply Units
24VDC and 48VDC regulated supplies for control system backbone. Repair focus includes capacitor ESR rise and drying, transformer short circuits, rectifier diode failures, and voltage regulation IC faults from thermal stress cycling.
CK-Comm Gateway Network Interface Cards
Ethernet and Profibus DP interface modules enabling plant-wide integration. Issues include RJ45 connector corrosion, transformer isolation core saturation, microcontroller firmware bugs, and clock oscillator phase drift in temperature extremes.

Common CONTROL KING Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in CONTROL KING equipment arriving at our workshop.
- ✓CK-3000 CPU module no boot-up, no LED indication — Control King CK-3000 CPUs are susceptible to onboard 3.3V regulator failure in high-temperature mill conditions exceeding 50C. Thermal cycling causes SMD capacitor ESR rise and regulator IC thermal runaway. Battery-backed SRAM corruption also prevents cold boot.
- ✓CK-Flex HMI touchscreen dead display, backlight on — Control King CK-Flex terminals suffer LCD LVDS cable intermittent contact in vibration-prone environments (printing presses, looms). Connector corrosion and PCB flex micro-cracks interrupt video signal, creating blank gray or black screen. Backlight LED supply remains functional.
- ✓CK-Drive servo module ERROR CODE E2 or E3 repeated fault — Control King CK-Drive IGBT power bridges degrade due to high-frequency PWM switching stress and inadequate heatsink coupling common in cramped electrical enclosures. Gate driver optocoupler aging also causes switching timing skew, triggering software watchdog E2/E3 faults.
- ✓CK-IO module loses half of input signals after power cycling — Control King CK-IO remote terminals experience relay contact stiction and welding in chemical plants with corrosive gas exposure. Analog isolation transformer insulation breakdown between primary and secondary windings causes intermittent input dropout on opto-isolated channels.
- ✓CK-PSU 24VDC output voltage sags to 18V under light load — Control King CK-PSU units suffer progressive voltage regulator IC performance degradation from repeated inrush current stress and thermal cycling in pharmaceutical GMP environments. Compensation network capacitor drying causes feedback loop instability.
- ✓CK-Comm Ethernet gateway card intermittent connectivity, packet loss — Control King CK-Comm-ETH cards suffer RJ45 connector pin corrosion and solder joint micro-cracks at the connector PCB interface, especially in food processing plants with high humidity and washdown environments. Crystal oscillator aging also causes frequency drift, degrading Ethernet timing margins.

Call our technical hotline to confirm availability and pre-arrange loaner delivery coordination.
How much does a Control King CK-Flex touchscreen repair typically cost?+
Control King CK-Flex repair costs depend on fault type and model size. LCD backlight replacement alone runs 8,000-15,000 INR. Full resistive touch panel replacement with LCD reseating costs 18,000-25,000 INR. LVDS connector rework is 6,000-10,000 INR. Synchronics provides free initial fault diagnosis and written quotation before any work begins. We offer one-year warranty on all CK-Flex repairs covering the same fault.
Can Synchronics repair Control King CK-Drive servo modules with burned IGBT chips?+
Yes, absolutely. IGBT and gate driver module burnout is one of the most common Control King CK-Drive failures we encounter. Synchronics performs full gate driver optocoupler replacement, installs matched IGBT modules rated to original current capacity, reworks thermal interface material, and performs dynamic brake-load testing to 110 percent rated current before release. We warranty all CK-Drive power stage repairs for 12 months.
