GJMICRO Product Lines We Repair
Our engineers are trained on the full GJMICRO product range. Below are the major product families we service.
GJM-MC Series Industrial Microcontrollers
32-bit ARM-based MCU modules for PLC interfacing and real-time process control. Common issues include flash memory corruption, bootloader faults, and peripheral interface failures in harsh industrial environments.
GJM-EMP Embedded Processing Modules
Modular embedded processors for motion control, data acquisition, and fieldbus communication. Typical failures involve thermal stress, solder joint degradation, and communication protocol stack errors.
GJM-IOC Industrial I/O Controller Cards
Analog and digital I/O expansion modules with multi-protocol support (Modbus, CAN, Ethernet). Common repair cases include ADC/DAC channel failures, relay driver burnout, and isolation transformer breakdown.
GJM-CommLink Protocol Interface Boards
Industrial communication interface modules for RS-485, CAN-bus, and Ethernet networking. Frequently repair network transceiver failures, RJ45 connector degradation, and protocol stack memory leaks.
GJM-Power Management ICs and Regulators
Integrated power supply and voltage regulation modules for industrial embedded systems. Repair focus includes input surge protection failure, output capacitor drying, and thermal runaway in SMPS circuits.
Why Choose Synchronics for GJMICRO Repairs?

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 GJMICRO Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in GJMICRO equipment arriving at our workshop.
- ✓GJMICRO flash memory corruption and firmware bootload failure — Sudden power loss during firmware upload, corrupted bootloader sector, or defective on-chip flash. Industrial EMI and voltage spikes are common triggers in Indian textile mills and chemical plants.
- ✓GJMICRO analog I/O channel dead or giving wrong readings — ADC/DAC chip failure, damaged reference voltage circuit, or broken input protection diodes in high-noise factory environments. Common in pharmaceutical batch-weighing systems.
- ✓GJMICRO CAN-bus or RS-485 communication dropout and node timeout — Physical layer transceiver IC failure, broken twisted-pair wiring, terminated impedance mismatch, or firmware protocol stack hang. Frequent in Indian automotive assembly lines.
- ✓GJMICRO power module thermal shutdown and brownout resets — SMPS electrolytic capacitors dried out, PWM control IC malfunction, or thermal sensor fault. High ambient temperatures in Indian foundries accelerate capacitor aging.
- ✓GJMICRO relay driver outputs stuck-on or no-output condition — Darlington transistor collector-emitter leakage, relay coil short, or gate-drive voltage loss from failed optoisolator. Common in Indian food processing control circuits.
- ✓GJMICRO processor lockup with no response to reset or interrupt — Watchdog timer firmware timeout, stack overflow in embedded code, RAM bit-flip from cosmic ray or EMI, or hung peripheral blocking CPU. Typical in long-runtime control applications.

Frequently Asked Questions — GJMICRO Repairs
Do you repair GJMICRO equipment anywhere in India?+
Yes. Synchronics repairs the full GJMICRO product range — microcontrollers, embedded processors, I/O cards, communication modules, and power regulators. We offer pan-India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Jaipur, Lucknow, and all major industrial cities. Same facility in Vadodara, Gujarat with 180+ engineers and fastest turnaround.
What GJMICRO fault codes do you specialize in diagnosing?+
Synchronics diagnoses all GJMICRO hardware and firmware error codes including bootloader errors (0xE001-0xE004), ADC/DAC range errors (0x80xx series), communication timeouts (0x40xx CAN/RS-485), and thermal shutdown codes (0x60xx). We use JTAG/SWD debuggers to extract fault logs, cross-reference GJMICRO technical docs, and pinpoint root causes at IC component level.
Can you reprogram GJMICRO flash memory and restore factory firmware?+
Absolutely. We have licensed GJMICRO firmware images for all GJM-MC, GJM-EMP, and GJM-IOC series. Using professional JTAG programmers and SWD interfaces, we read/write flash sectors, validate checksums, set security fuses safely, and test functionality before return. Critical for Indian manufacturers who lose source code or experience firmware corruption during power loss.
How long is typical repair turnaround for GJMICRO modules?+
Most GJMICRO embedded controller repairs complete in 5-7 working days at Synchronics. Complex firmware issues or multi-layer rework may take 10-14 days. We offer express 48-hour repair for urgent situations and provide loaners for critical production lines. All repairs include full functional test and 12-month warranty.
Do you offer on-site GJMICRO repair and preventive maintenance in Gujarat and Maharashtra?+
Yes. Synchronics provides on-site diagnostics, firmware updates, and preventive capacitor replacement programs for GJMICRO-based control systems at Indian pharma, textile, and automotive facilities. We visit your plant, test boards under operating conditions, identify aging components, and schedule repairs during maintenance windows.
How do I send my GJMICRO 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 GJMICRO 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 GJMICRO 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 GJMICRO 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.
