HOLITECH Product Lines We Repair
Our engineers are trained on the full HOLITECH product range. Below are the major product families we service.
HOLITECH LED Display Controllers
Industrial-grade LED display driver boards and control modules for process monitoring, production dashboards, and temperature displays. Common issues include LED segment failures, power supply failures in driver circuits, and display flicker due to refresh rate instability.
HOLITECH Thermal Management Modules
Precision temperature control boards and thermal interface electronics for furnaces, ovens, and process heating systems. Repair focuses on thermocouple interface failures, PID controller drift, and thermal sensor signal conditioning issues.
HOLITECH Industrial Relay & Switch Modules
Solid-state and electromechanical relay control boards for motor starting, load switching, and power management in Indian textile and packaging machinery. Failures include relay coil burnout, optocoupler degradation, and triac short-circuit faults.
HOLITECH Sensor Interface & Signal Conditioning
Precision analog signal conditioning boards for pressure transducers, flow sensors, and weight sensors used in pharmaceutical and chemical manufacturing. Common faults include amplifier saturation, filter capacitor drying, and sensor excitation supply failure.
HOLITECH Industrial UPS & Power Supply Modules
Compact uninterruptible power supplies and isolated DC converters for PLC backup and critical control systems. Repair targets include battery management failures, inverter topology faults, and output voltage regulation issues under transient load.
HOLITECH Industrial Ethernet & Communication Modules
Industrial Ethernet to serial gateway boards and fieldbus interface modules for legacy machinery integration in Indian plants. Common problems include PHY chip failure, magnetics transformer open circuit, and firmware corruption on embedded processors.

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 HOLITECH Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in HOLITECH equipment arriving at our workshop.
- ✓LED display segments completely dark or flickering — HOLITECH LED driver ICs (typically HT74HC595 or similar shift register equivalents) experience column/row decode failures, or the display multiplexing refresh clock is degraded due to crystal oscillator aging or timing capacitor drying in the display controller.
- ✓Temperature reading shows -50C or max-out error code — HOLITECH thermocouple input boards suffer from open thermocouple junctions, cold-junction compensation amplifier IC failure (often a precision Op-Amp like TL071), or a fractured component leg on the reference junction board.
- ✓Relay contacts stuck closed or fails to energize coil — HOLITECH relay driver modules experience coil pull-in transistor short-circuit, flywheel diode reverse leakage, or electromagnetic interference (EMI) coupling onto the control signal, common in Indian textile mills with heavy induction motors.
- ✓4-20mA sensor signal reads constant 3.8mA regardless of input — HOLITECH sensor conditioning boards have failed input buffer amplifiers (saturation in precision Op-Amp stages), or the excitation supply regulator has drifted due to reference resistor tolerance shift and aging feedback capacitors.
- ✓UPS battery not charging or inverter producing distorted output — HOLITECH UPS modules fail due to battery management IC timeout (charger supervisor watchdog resets), boost/buck converter MOSFET short, or inverter PWM timing skew from corrupted gate driver firmware on the embedded controller.
- ✓Ethernet module not linking or packet loss intermittent — HOLITECH industrial Ethernet boards suffer from PHY transceiver IC lockup, transformer primary-secondary coupling capacitor opens or shorts, or connector pin corrosion from humid industrial environments common in Indian coastal manufacturing zones.

Frequently Asked Questions — HOLITECH Repairs
Do you repair HOLITECH equipment anywhere in India?+
Yes. Synchronics repairs the full HOLITECH product range including LED display controllers, thermal management modules, relay drivers, sensor interfaces, UPS systems, and Ethernet gateways. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Surat, Indore, and all other cities. All repairs are completed at our main facility in Vadodara, Gujarat, with standard 7-10 day turnaround and same-day repair for critical boards.
Why do HOLITECH thermal sensor boards fail in Indian textile mills?+
Indian textile mills operate in humid, dust-laden environments with high vibration from machinery and frequent power fluctuations. HOLITECH precision thermocouple boards are sensitive to moisture ingress (causing corrosion of bond wires in input amplifiers), thermal cycling stress on solder joints, and EMI from mill machinery. Synchronics uses conformal coating and component-level rework to harden these boards for textile mill conditions.
Can you replace HOLITECH LED driver ICs if segments are dark?+
Absolutely. HOLITECH LED display boards often fail at the shift-register or BCD-decoder IC level. Synchronics performs comprehensive LED scanning to identify which driver chips are faulty, de-solder the failed ICs using precision equipment, and install exact replacements. We then run all display patterns to confirm proper segment illumination and proper refresh rate.
What is the cost and timeline for HOLITECH relay module repair?+
HOLITECH relay driver repairs typically cost INR 2,500-6,000 depending on component count and IC count. Standard turnaround is 5-7 working days from receipt at our Vadodara facility. Expedited repairs (24-48 hours) are available for critical production equipment at an additional charge. All repairs include parts replacement and 6-month warranty.
Do you stock HOLITECH replacement components?+
Yes. Synchronics maintains inventory of commonly replaced HOLITECH components — precision Op-Amp ICs, precision voltage references, power MOSFETs, gate drivers, relay coils, isolation transformers, and sensor connectors. For rare or unavailable parts, we source compatible industrial-grade equivalents and validate them against HOLITECH specifications before installation.
How do I send my HOLITECH 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 HOLITECH 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 HOLITECH 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 HOLITECH 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.
