OPTREX Equipment We Repair — By Category
OPTREX Product Lines We Repair
Our engineers are trained on the full OPTREX product range. Below are the major product families we service.
Optrex LCM Series (Character & Graphic LCDs)
Monochrome and small-format LCD modules for industrial instrumentation, process meters, and embedded applications. Common failures include CCFL backlight degradation, segment loss, and controller IC burnout from voltage transients in manufacturing environments.
Optrex Industrial Monitor Series
Ruggedized LCD monitors (5.7-inch to 15-inch) for factory floor operator panels and automated machinery control. Prone to thermal stress failures, liquid crystal degradation in high-humidity environments, and power supply board capacitor aging in continuous-duty applications.
Optrex Monochrome LCD Panels (STN / FSTN)
Passive matrix and active matrix displays for automotive dashboards, test equipment, and legacy industrial control systems. Failures manifest as scan line loss, dead pixel clusters, and LCD ghosting due to improper storage or electrostatic discharge.
Optrex Colour LCD Modules (TFT)
TFT colour display units for advanced HMI panels, real-time process visualization, and operator interface systems in modern Indian manufacturing plants. Susceptible to backlight inverter failures, colour shift after thermal cycling, and timing controller IC defects.
Optrex OLED Micro-Display Technology
High-contrast, low-power OLED microdisplays for precision measurement instruments and inspection equipment. Rare but critical failures include pixel degradation, brightness loss due to organic material aging, and power management circuit failures.

Common OPTREX Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in OPTREX equipment arriving at our workshop.
- ✓CCFL backlight complete failure or dimming — Optrex LCM and Industrial Monitor series use Cold Cathode Fluorescent Lamp backlights that degrade after 30,000-50,000 hours of continuous operation. Inverter circuit aging, worn electrode coatings, and mercury depletion cause brightness loss or total blackout without affecting the LCD panel itself.
- ✓Pixel segment loss or dead pixel clusters — Optrex LCD panels suffer pixel defects when exposed to electrostatic discharge, thermal stress from rapid temperature swings in Indian industrial environments, or defective LCD driver ICs from manufacturing defects. Character/graphic displays show missing segments; TFT panels show dark pixel groups.
- ✓Colour shift or incorrect colour display on TFT panels — Optrex TFT colour modules suffer colour drift due to aged colour filter arrays, failing colour management ICs, or improper backlight inverter voltage regulation. High-temperature storage or thermal cycling in Indian summer conditions accelerates organic dye degradation.
- ✓No display response to input signals (dead panel) — Optrex LCM and HMI displays fail to respond when the timing controller IC, interface driver, or power management circuit experiences permanent damage from power surges, reverse polarity, or prolonged electrostatic exposure common in Indian manufacturing plants without proper ESD controls.
- ✓LCD ghosting or slow response time — Optrex STN and FSTN passive matrix displays exhibit ghosting (trailing image) when the liquid crystal alignment degrades or voltage drivers deliver inconsistent signal timing. Mechanical stress from thermal cycling or improper mounting can shift optical alignment.
- ✓Touch panel intermittent or non-responsive (Optrex Touch-Enabled HMI) — Optrex integrated touch panels fail when the resistive or capacitive touch controller IC develops dry solder joints, the touch sensor layer delaminates due to moisture ingress, or the interface cable develops intermittent connections from vibration and thermal stress in factory environments.

Frequently Asked Questions — OPTREX Repairs
Do you repair Optrex equipment anywhere in India?+
Yes. Synchronics repairs the complete Optrex product range — LCM character displays, industrial monitors, TFT colour panels, and HMI units. We offer PAN India door pickup and delivery from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Nagpur, and all tier-2 cities. All repairs are performed in our Vadodara, Gujarat facility with 30+ years of display electronics expertise.
What is the turnaround time for Optrex LCD module repair?+
Standard repairs take 3-5 working days after diagnosis. Backlight replacement, controller IC repair, and touch panel fixes are completed within this window. Urgent expedited service (24-48 hours) is available for critical production line equipment. We provide daily status updates and advance notification before pickup.
Can Synchronics repair legacy Optrex monochrome LCD panels that are no longer in production?+
Yes. Synchronics specializes in legacy Optrex STN, FSTN, and character LCD repair. Even if your model is 10-15 years old, we can source compatible replacement components, repair driver ICs, and restore functionality. We maintain stock of common Optrex LCD controller ICs, CCFL tubes, and inverter modules for rapid repair turnaround on discontinued models.
What warranty do you offer on repaired Optrex displays?+
All Optrex repairs carry a 12-month parts warranty and 6-month labour warranty covering the repaired component or circuit. Extended 24-month warranties are available on high-criticality HMI panels and industrial monitors. Warranty covers defects arising from our repair work, excluding normal wear, mishandling, or continued environmental stress.
How much does Optrex LCD repair typically cost compared to buying new?+
Synchronics repair costs 40-60% of new panel prices for most Optrex displays. Backlight and controller IC repairs average Rs. 3,000-8,000. Industrial monitors cost Rs. 8,000-15,000. We provide written quotes after free diagnosis. For high-value HMI panels, repair ROI is typically 6-12 months, making refurbishment economical for most Indian manufacturers managing equipment lifecycles.
How do I send my OPTREX 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.
What is the cost of repairing a OPTREX 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 OPTREX 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 OPTREX 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.
