Industrial machine vision cameras and sensors are the core of modern factory automation — quality control, robot guidance, 3D measurement, weld inspection, product sorting. A new inspection camera costs between 3,000 and 85,000 PLN depending on the manufacturer and model. Acore from Knurow, Poland specializes in the diagnostics and repair of these devices, accepting equipment from all over Poland, Germany, Czech Republic, Slovakia and the rest of Europe.
Repaired Device in Our Workshop — ifm O3D361 3D Vision Sensor
The photographs show an ifm electronic O3D361 — an industrial 3D Time-of-Flight (ToF) sensor rated IP67/IP69K, 20.4-28.8 V DC, 1.6 A avg / 2.4 A peak, Made in Germany. The unit arrived at Acore with symptoms of no object detection and a solid red status LED instead of green. Diagnosis: blown VCSEL (Vertical-Cavity Surface-Emitting Laser) diode driver in the IR illuminator module and a failed capacitor C12 in the DSP power supply section.
Common Machine Vision Camera Faults
No Image — Camera Not Detected
Camera connected via GigE Vision / USB3 but not found by the configuration software. Root causes: blown GigE PHY (Marvell 88E1111, Micrel KSZ9031), failed polymer fuse on 3.3V rail, blown USB3 controller (Cypress CYUSB3014), corrupted SPI NOR flash firmware, Camera Link trace break. Repair cost: 400-1,500 PLN.
Red Status LED / Detection Error
Device powers on but LED is solid red or blinks in error pattern. Typical on ifm O3D3xx, SICK Visionary-T, Leuze LSIS. Root causes: blown VCSEL driver IC MAX4295, failed 850 nm VCSEL laser diode, FPGA configuration error (Xilinx Spartan-6 DONE pin low), oxidized M12 connector pin, faulty NTC temperature sensor. Repair: 600-2,200 PLN.
Blurry Image, Noise, Vertical Stripes
Camera operational but image quality unacceptable. Causes: damaged CMOS sensor (dead pixels, dead columns from ESD or overexposure), loose lens module, failed AFE (Analog Front End) amplifier, condensation on protective glass, damaged IR-cut filter. Repair: 1,200-4,500 PLN.
GigE Communication Errors / Packet Loss
Camera detected on network but image stream drops or high latency. Causes: blown EMI filter on RJ45, desoldered bypass capacitor on 3.3V GigE PCB, failed SoC processor (i.MX6, Zynq-7000), FPGA thermal throttling without TIM. Repair: 400-1,800 PLN.
Built-in LED Ring / Laser Line Not Working
Camera operates normally but integrated illumination does not activate. Causes: blown LED driver IC (TI TPS61187, LM3466), failed MOSFET (IRLML6344), broken flex cable to LED board, faulty NTC on LED PCB blocking power. Repair: 350-900 PLN.

FAQ
- Does repairing a machine vision camera erase the inspection program?
- No. Inspection programs are stored in flash memory or on a microSD card which we do not touch during electrical repair. In the rare case of flash replacement, we perform a full backup via the service port or Ethernet beforehand.
- ifm O3D361 solid red LED and no object detection — is this repairable?
- Yes. Solid red LED most commonly indicates a blown VCSEL driver circuit or failed IR diodes. Diagnosis takes 1 day, repair 1-2 days. 12-month warranty on all repaired components.
- Do you repair line scan cameras for printing and film inspection?
- Yes - Basler racer, Teledyne DALSA Linea/Piranha, JAI LQ-400CL. Most common faults: Camera Link HS PHY failure, damaged LVDS outputs, EXSYNC synchronization loss.
- Can you repair a Cognex In-Sight 7000 without losing the license?
- Yes. The In-Sight license is tied to the hardware serial number, not to the main PCB. Replacing a faulty component (PHY, capacitor, MOSFET) does not change the serial number.
- What is the shipping cost from Germany?
- Flat rate 80 PLN (approx. 18 EUR) for shipping both ways, insured up to 50,000 PLN. Express courier pickup at our cost for repairs above 3,000 PLN.
- How long does repair take?
- Standard: 2-5 business days from receipt. Express 24h service available for contract customers. Cameras with damaged FPGA or CMOS may require up to 7 business days for specialist component sourcing.
