Expert Chunghwa LED driver and power module repair — board-level diagnostics and firmware restoration.
CHUNGHWA Product Lines We Repair
Our engineers are trained on the full CHUNGHWA product range. Below are the major product families we service.
Chunghwa LED Driver Modules
Constant-current LED control boards integrated into Indian LED packaging and display equipment. Common issues include capacitor failures, PWM signal loss, and thermal management degradation in high-humidity plant environments.
CPT Industrial Power Supply Units
Compact switched-mode power supplies (100W-500W) embedded in textile machinery and packaging automation. Failure modes include electrolytic capacitor leakage, transformer saturation, and optocoupler decay leading to voltage regulation faults.
Chunghwa Automation Control Cards
Single-board industrial controllers with relay outputs used in Indian beverage filling, pharmaceutical blister, and textile inspection systems. Repairs involve EEPROM programming, relay contact restoration, and crystal oscillator replacement.
CPT Embedded Optoelectronic Sensors
Photo-interrupter and optical isolation modules used in Indian packaging machinery and textile looms for speed detection and synchronization. Common faults include phototransistor degradation and LED aperture contamination.
Chunghwa Temperature and Process Controllers
Programmable control modules for industrial ovens, curing presses, and thermal processing equipment. Repair involves NTC thermistor characterization, relay calibration, and display segment restoration.

Common CHUNGHWA Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in CHUNGHWA equipment arriving at our workshop.
- ✓LED driver PWM output loss or dimming — Chunghwa LED driver modules suffer capacitor leakage in the feedback network, causing PWM signal instability. Indian plant environments with high humidity and 45°C ambient temperatures accelerate electrolytic capacitor ESR drift, particularly on CPT-LD series boards.
- ✓Power supply voltage regulation failure or shutdown — Chunghwa PSU modules fail when the optocoupler feedback loop degrades, causing the regulator IC to lose control authority. In Indian textile mills with voltage spikes (175-280V input swings), transformer core saturation compounds the issue, triggering protection foldback.
- ✓Automation control card input/output relay failure — Chunghwa ACC relay contacts oxidize and stick in Indian industrial environments, particularly in beverage and pharma filling lines where moisture and CO2 levels fluctuate. Inductive load spikes from solenoid switching accelerate contact erosion.
- ✓Temperature controller display segment loss or no display — Chunghwa TCC modules develop LCD segment faults when the DC bias voltage drifts due to capacitor aging in the display driver circuit. Indian semiconductor assembly cleanrooms with low humidity accelerate dielectric stress on display interface capacitors.
- ✓Sensor phototransistor response slow or no detection — Chunghwa optoelectronic sensor modules (CPT-PS series) degrade when LED apertures accumulate dust from Indian textile fibers or food packaging line contaminants. Phototransistor junction leakage increases with age, reducing sensitivity on high-speed detection circuits.
- ✓EEPROM corruption or program loss in control cards — Chunghwa ACC boards experience EEPROM data loss during power brownouts, particularly in Indian plants with unstable grid supply. Firmware CRC failures cascade when the battery-backed write-protection circuit fails.

Frequently Asked Questions — CHUNGHWA Repairs
Do you repair Chunghwa equipment across India?+
Yes. Synchronics has repaired Chunghwa LED drivers, power supplies, and control cards for textile mills in Tiruppur, beverage plants in Gujarat and Maharashtra, and pharma packaging lines across Tamil Nadu and Telangana. We offer free PAN-India door pickup and return courier service. Submit equipment via our Vadodara facility.
What Chunghwa product families does Synchronics repair?+
We repair all major Chunghwa industrial electronics: LED driver modules (CPT-LD series), embedded power supplies (CPT-PSU), automation control cards (CPT-ACC), optoelectronic sensors (CPT-PS), and temperature controllers (CPT-TCC). Board-level repair includes component-level diagnostics, firmware recovery, and full functional test per OEM specifications.
How long does Chunghwa equipment repair typically take?+
Standard Chunghwa board repair (capacitor replacement, relay cleaning, firmware reprogramming) takes 5-7 working days from receipt. Complex failures requiring custom test jigs or component procurement extend to 10-12 days. We provide daily progress updates and expedited turnaround (3-5 days) for critical production line equipment with rush fees.
Do you stock Chunghwa replacement components?+
Synchronics maintains stock of common Chunghwa capacitors, optocouplers, relays, and phototransistors used in CPT-LD and CPT-PSU modules. For proprietary Chunghwa chips and custom LCD modules, we procure from Asian electronics distributors with 3-5 day lead times. We can often repair without waiting for components through cross-reference analysis and functional substitution.
Can you repair Chunghwa equipment if I do not have the original documentation?+
Yes. Synchronics engineers reverse-engineer Chunghwa boards through PCB photography, component tracing, and signal analysis. We maintain an internal library of CPT schematics and firmware signatures from 20+ years of industrial repair. Even undocumented custom Chunghwa control cards can be diagnosed and repaired through functional testing and comparative analysis with known good units.
How do I send my CHUNGHWA 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 CHUNGHWA 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 CHUNGHWA 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 CHUNGHWA 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.
