LG Equipment We Repair — By Category
LG Product Lines We Repair
Our engineers are trained on the full LG product range. Below are the major product families we service.
LG Industrial LCD/LED Displays
LG's commercial-grade display solutions for retail, automotive dashboards, and industrial monitoring. Common faults include backlight failures, panel dead zones, driver IC degradation, and power supply module breakdown affecting image quality and operational reliability.
LG Inverter Compressor Controllers
Advanced BLDC controllers for LG refrigeration and air conditioning systems. Frequent issues include thermal runaway, capacitor failure, PWM driver chip breakdown, and commutation errors leading to compressor lockup or inefficient cooling cycles.
LG Power Conditioning Units
Industrial power factor correction and voltage stabilization modules. Repair requirements include IGBT failures, snubber capacitor explosions, harmonic filter degradation, and protection relay malfunction preventing proper power management.
LG Automotive Display Systems
Cluster and infotainment displays for commercial vehicles and heavy-duty transportation. Common defects are CAN bus communication failures, pixel dropout, cold-solder joint failures, and EEPROM corruption affecting vehicle diagnostics display.
LG Smart Building HVAC Controllers
IoT-enabled air handling and thermal management systems for commercial complexes. Typical failures include Ethernet port corrosion, firmware corruption, humidity sensor drift, and relay contact pitting causing temperature regulation failure.
Why Choose Synchronics for LG Repairs?

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 LG 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 LG Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in LG equipment arriving at our workshop.
- ✓LG LCD panel backlight complete failure — WLED driver IC overheating due to inadequate thermal management in high-temperature industrial environments. Electrolytic capacitor drying causes voltage regulation collapse in the backlight power supply.
- ✓LG inverter compressor thermal protection trip — Overload on BLDC phase legs caused by bearing wear, junction temperature sensor malfunction, or software firmware bug in the current-limiting algorithm. Desert and coastal humidity accelerate component corrosion.
- ✓LG display CAN-BUS communication dropout — Cold solder joints on CAN transceiver pins, termination resistor network failure, or shielding cable corrosion in automotive environments expose the differential bus to EMI and signal reflections.
- ✓LG power factor correction capacitor bank swelling — Ripple current overstress from unbalanced three-phase loads and inadequate pre-charge circuit design. Humid Indian manufacturing floors and power surges trigger internal pressure buildup and electrolyte degradation.
- ✓LG HVAC controller Ethernet port non-responsive — Corrosion of RJ45 connector pins from moisture ingress in high-humidity areas. Network transformer saturation and PHY IC thermal stress disable communication without power loss.
- ✓LG automotive cluster display pixel rows missing — LVDS interface timing margin violation from dried capacitors on the LCD controller board. Temperature cycling and vibration loosen solder balls under BGA memory ICs and display connectors.

Frequently Asked Questions — LG Repairs
Do you repair LG equipment anywhere in India?+
Yes. Synchronics repairs the full LG product range - industrial displays, HVAC controllers, power conditioning units, and automotive systems. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, and all other cities. All repairs are processed at our ISO 9001 facility in Vadodara, Gujarat, with 5-7 day standard turnaround.
Why do LG inverter compressor controllers fail in Indian summer conditions?+
LG controllers are rated to 55°C ambient, but Indian industrial facilities often exceed this during peak summer. Combined with 60%+ humidity in coastal areas, thermal stress on electrolytic capacitors accelerates degradation. Synchronics uses conformal coating and upgraded thermal interface materials to rebuild these units for 60°C+ operation reliably.
Can Synchronics repair LG display CAN-BUS faults in commercial vehicles?+
Absolutely. Automotive displays face extreme vibration and EMI from engine harnesses. Synchronics performs full CAN termination re-qualification, replaces connector seals, and validates communication under vehicle-speed simulation. We maintain a test bench mimicking heavy-duty truck electrical environments found across Indian highways.
What is the warranty on repaired LG equipment from Synchronics?+
All LG repairs carry 12 months functional warranty and 6 months on replaced components. Critical industrial displays and HVAC controllers qualify for extended 24-month warranties. We provide genuine LG spares where available and ISO-certified alternatives where LG components are EOL - all documented with full traceability.
Do you offer preventive maintenance contracts for LG HVAC and display systems?+
Yes. Synchronics offers quarterly preventive maintenance for LG smart building controllers and industrial displays deployed in data centers, pharma cold storage, and retail chains. We include capacitor health scoring, firmware updates, and thermographic inspection - reducing unplanned downtime by 70% across Indian customer installations.
How do I send my LG 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 LG 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 LG 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 LG 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.
