DOLCH Product Lines We Repair
Our engineers are trained on the full DOLCH product range. Below are the major product families we service.
DOLCH Fanless Industrial PC Chassis
Sealed, fanless computers designed for dusty, vibration-prone factory environments. Common issues include failed aluminum heatsinks, corroded internal connectors, BIOS corruption, and memory module failures due to thermal cycling.
DOLCH Industrial Panel PC / HMI Systems
Integrated touchscreen and display-based control systems for production line monitoring. Repair challenges include LCD backlight degradation, resistive/capacitive touch controller failure, video signal loss, and thermal management in sealed enclosures.
DOLCH Mobile Rugged Computers
Vehicle-mounted and handheld industrial computers for logistics, mining, and field operations. Common faults include connector corrosion, dropped frame damage, battery charging circuit failures, and keyboard/trackpad malfunctions.
DOLCH Motherboards and Embedded Modules
Core compute modules used in OEM applications, automation cabinets, and IoT gateways. Typical failures: failed power delivery ICs, RAM slot deterioration, onboard chipset overheating, and CMOS battery depletion.
DOLCH Power Supply Units (PSU)
Redundant and sealed power supplies built for uninterrupted industrial operation. Failure modes include blown electrolytic capacitors, failed MOSFETs, loose solder joints, and voltage regulation drift.

Common DOLCH Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in DOLCH equipment arriving at our workshop.
- ✓DOLCH PC no-boot, LED status frozen — Sealed fanless DOLCH chassis suffer thermal throttling and BIOS flash corruption after sudden power loss or prolonged high ambient temperature (>50°C). Capacitor aging is accelerated in heat-stressed confined spaces.
- ✓DOLCH Panel PC touchscreen unresponsive or ghost touches — Resistive and capacitive touch controllers on DOLCH HMI panels fail due to high humidity ingress (common in Indian textile mills, steel plants), corrosion of flex cable connectors, or firmware version mismatch after OS update.
- ✓DOLCH computer intermittent shutdown or random resets — Failed bulk capacitors in the power delivery stage cause voltage sagging during load spikes. Dry solder joints on BGA components and thermal expansion cycling in fanless chassis compound the issue, especially in Indian plants with poor climate control.
- ✓DOLCH motherboard video output loss or no HDMI signal — Integrated video chipsets on DOLCH embedded modules degrade due to repeated thermal stress cycles. Loose HDMI connectors and damaged video lane routing (from vibration in mobile/vehicle DOLCH systems) are common in Indian mining and logistics operations.
- ✓DOLCH memory failures or intermittent parity errors — DOLCH systems use industrial-grade RAM, but poor socket contact, corrosion of DIMM pins, or defective onboard voltage regulator for memory supply cause errors. High vibration in factory floors accelerates contact wear.
- ✓DOLCH redundant PSU failover not working — Dual power supply systems in DOLCH industrial PCs fail when the OR-ing diodes, sense circuits, or battery backup relays age or when power budget calculations drift. Thermal stress on OR diodes is common in sealed chassis.

Frequently Asked Questions — DOLCH Repairs
Do you repair DOLCH computers and embedded systems anywhere in India?+
Yes. Synchronics is a certified repair partner for DOLCH industrial PCs, panel computers, rugged motherboards, and power supplies. We offer PAN-India pickup from all major cities including Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, and Kolkata. All repairs are performed at our ISO-certified facility in Vadodara, Gujarat. Turnaround time is typically 5-7 working days, with emergency repairs available.
What DOLCH product lines do you repair, and what is your experience with fanless chassis systems?+
Synchronics repairs the entire DOLCH range: fanless industrial PC chassis (CX series), industrial panel PCs and HMI systems (PAC series), mobile/vehicle-mounted computers, embedded CPU modules, and redundant power supplies. We have specialized expertise in fanless DOLCH systems because we understand the thermal challenges specific to sealed designs used in harsh Indian manufacturing environments. Our engineers have repaired over 500+ DOLCH units in automotive plants, steel mills, and mining operations across India.
My DOLCH fanless PC is stuck in thermal shutdown — what causes this and how do you fix it?+
Thermal shutdown in DOLCH fanless chassis is usually caused by aged aluminum heatsink compound degradation, failed thermal interface material, dust/debris clogging cooling fins, or a failed temperature sensor. In Indian plants with high ambient temperatures (40-50°C+) and poor cabinet ventilation, this is common. Synchronics disassembles the sealed chassis, cleans the cooling paths, replaces thermal paste and pads, tests the temperature sensor circuit, and runs thermal stability tests under simulated load before returning the unit.
Can Synchronics repair DOLCH motherboards with failed BGA components or solder cracks?+
Yes. Synchronics has in-house BGA rework equipment with thermal profiling. We can reflow or replace failed video chipsets, power delivery ICs, and other BGAs on DOLCH embedded modules. We also perform X-ray inspection to detect cracks invisible to the eye and apply selective reflow to problem areas. All BGA work is followed by thermal cycling tests to ensure long-term reliability.
Do you stock spare parts for DOLCH computers, and what is your parts availability?+
Synchronics stocks a range of DOLCH spares including electrolytic and tantalum capacitors, DDR3/DDR4 RAM modules, HDMI connectors, LCD display panels, touch controller ICs, and power supply components. For obsolete DOLCH modules or full motherboard replacements, we can source components through our vendor network in 3-5 working days. We can also provide reference designs if you need to upgrade legacy DOLCH systems with compatible alternatives.
How do I send my DOLCH 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 DOLCH 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 DOLCH 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 DOLCH 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.
