Common Issues When Using Video Borescopes and How to Troubleshoot Them?

Q1: Why is the image blurry or out of focus?
A:
This can be caused by:
Incorrect focus distance: Ensure the probe tip is within the optimal focus range (usually 10mm–100mm depending on the lens). Dirty lens or protective cover: Gently clean the lens with a soft cloth or alcohol swab.Condensation or moisture: Allow the unit to dry or use anti-fog lens coatings.

Q2: My borescope won't power on. What should I check?
A:
Battery level: Make sure the battery is charged or properly installed.
Loose cables: Check the power cable connection between the monitor and the probe.
Damaged buttons or circuit board: Contact the manufacturer if the power button is unresponsive after confirming power supply.

Q3: Why is there no video signal or a black screen?
A:
Signal loss or poor connection: Ensure the video cable or HDMI/USB connection is secure.
Damaged probe or camera module: Inspect the probe for signs of physical damage.
Monitor settings: Confirm that the correct input source is selected on the monitor.

Q4: The LED light is not working. What could be wrong?
A:
Light intensity set to zero: Increase brightness via the control panel or app.
Worn-out LED module: The light source may need to be replaced after long-term use.
Cable failure: Inspect for any pinched or frayed cables connecting the light source.

Q5: The device gets hot quickly. Is that normal?
A:
Some heat is normal during extended use, especially with high-brightness LEDs.
If the unit becomes too hot to touch, ensure:
Proper ventilation is available.
You are not exceeding recommended operating time.
Internal fans (if applicable) are working correctly.

Q6: The probe tip is difficult to steer or doesn’t respond well.
A:
Mechanical wear: Steering cables may be stretched or broken.
Debris or oil inside the articulation mechanism: Clean and lubricate if allowed.
Exceeding bending limits: Avoid forcing the probe to bend beyond its rated articulation range.

Q7: Why is my recorded video missing or corrupted?
A:
Improper ejection of memory card: Always use the proper shutdown procedure.
Low-quality or incompatible memory card: Use manufacturer-recommended SD cards (e.g., Class 10 or UHS-I).
