HCI Product Lines We Repair
Our engineers are trained on the full HCI product range. Below are the major product families we service.
HCI Industrial Power Supplies
Robust 24VDC, 48VDC, and custom voltage regulated supplies for PLC, HMI, and field instrument power distribution. Common faults include capacitor failures, voltage regulation drift, and thermal management issues in high-ambient environments typical of Indian foundries and textile mills.
HCI Programmable Logic Controllers (PLC)
Compact and modular PLCs designed for machine automation and process control in oil, gas, and manufacturing sectors. Frequent repair needs include input/output module failures, battery backup depletion, and communication port corruption from electrical noise.
HCI Servo Drive Systems
AC servo and brushless DC motor drives for precision positioning and motion control in printing, converting, and assembly equipment. Common issues: firmware corruption, MOSFET gate driver failures, encoder signal loss, and thermal overload trips under sustained load.
HCI Human-Machine Interface (HMI) Terminals
Industrial touchscreen panels and operator interfaces with built-in communication gateways for Modbus, Ethernet, and legacy serial protocols. Typical faults: touchscreen sensor degradation, communication module failures, and corrupted display firmware from power transients.
HCI Custom Automation Modules
Application-specific control boards for temperature management, motor soft-start, pump speed regulation, and data acquisition. Repair challenges include specialized component obsolescence and lack of third-party documentation in Indian market.
Why Choose Synchronics for HCI Repairs?
PCB-Level Expertise
We repair down to the component level — not just swap boards. Our engineers identify root causes, replace failed IGBTs, capacitors, processors, and gate drivers on HCI equipment.
Fast Turnaround
Standard 7–10 working days. Express 3–5 days available for critical breakdowns. Emergency same-day/next-day service for unplanned downtime.
6-Month Warranty
Every repaired unit ships with a 6-month comprehensive warranty on parts and labour. Our repair success rate is over 94% across all brands.
All-India Service
Couriered repairs accepted from any city in India. Doorstep pickup available in Vadodara, Mumbai, Pune, Ahmedabad, Surat, Chennai, and more.
Common HCI Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in HCI equipment arriving at our workshop.
- ✓HCI power supply voltage regulation failure — Electrolytic capacitor degradation in primary filter stage or feedback circuit error amplifier IC failure. Typical in humid Indian climates where condensation accelerates capacitor aging.
- ✓HCI PLC communication port dead or intermittent — ESD damage to RS-485 or Ethernet PHY transceiver IC, often from inadequate shielding in noisy Indian factory environments with ungrounded cable trays and frequent lightning transients.
- ✓HCI servo drive no enable or fault code locked — MOSFET gate driver IC malfunction, shorted bootstrap capacitor, or corrupted drive firmware preventing proper phase-leg switching. Common after thermal cycling in furnace-adjacent installations.
- ✓HCI HMI touchscreen unresponsive or partial touch — Resistive or capacitive touch sensor layer short-circuit, controller IC reset failure, or display data bus parity error from EMI coupling in plants with high-frequency induction heating.
- ✓HCI encoder feedback signal loss or glitch — Incremental or absolute encoder interface IC failure, corrupted decoder firmware, or cable shield grounding issue causing differential signal noise in environments with variable-frequency drives.
- ✓HCI module firmware corruption or code upload failure — Power interruption during programming, flash memory bit-flip from electrical transient, or bootloader IC defect preventing re-flash sequence entry.

Frequently Asked Questions — HCI Repairs
Do you repair HCI equipment anywhere in India?+
Yes. Synchronics repairs the complete HCI product range — power supplies, PLCs, servo drives, HMIs, and custom automation modules. We operate PAN India courier pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Bangalore, Ahmedabad, Kolkata, and 50+ other cities. All repairs are performed at our Vadodara, Gujarat facility by certified engineers with genuine HCI component stock.
What is your typical turnaround time for HCI servo drive repairs?+
Most HCI servo drives are diagnosed and repaired within 5-7 working days. Rush turnaround of 2-3 days is available for critical production line stoppages. We provide real-time email updates and digital images of faults found. All drives are load-tested at rated voltage and frequency before dispatch.
Do you repair obsolete HCI modules and legacy controllers?+
Yes. Synchronics maintains extensive inventory of legacy HCI components dating back 15+ years. Even if an HCI module is out of production, we can often source equivalent ICs, reprogram firmware backups, or design compatible daughter-card retrofits. We have successfully repaired HCI equipment from 1990s installations in Indian sugar mills and spinning plants.
Can you provide on-site troubleshooting for HCI control system failures?+
Absolutely. Our field service team can visit your plant in Gujarat, Maharashtra, Karnataka, Tamil Nadu, Telangana, and Rajasthan for in-situ diagnostics of HCI PLC, HMI, and drive-based automation systems. We bring portable oscilloscopes, multimeters, and HCI test loads to isolate faults before removal. Estimated on-site support: INR 8,000-15,000 per day plus travel.
Do you repair HCI equipment with partial or cosmetic damage?+
Yes. Even if your HCI power supply or PLC has corroded connectors, burned terminal blocks, or dented enclosures, Synchronics can restore full functionality. We clean corrosion using specialized solvents, replace connectors and contact pins, recalibrate potentiometers, and test all I/O points. Cosmetic restoration is available upon request.
How do I send my HCI 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 HCI 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 HCI 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 HCI 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.
