When your sewer camera stops working, the problem is usually not as complex as it seems.
In most cases, the issue comes down to a few common causes such as power failure, loose connections, damaged cables, or component wear.
Instead of guessing or sending the system for repair right away, you can follow a simple step-by-step process to identify the problem.
This guide walks you through how to diagnose sewer camera problems step by step, so you can quickly find the issue and decide whether it can be fixed on-site or needs repair.

Not Sure If You Need Repair or Replacement?
What to Check First (Quick Diagnosis)
Before going step by step, start with these quick checks:
- Is the system turning on?
- Is there image on the screen?
- Are the lights working?
- Is the cable responding when pushed?
These answers will help you narrow down the issue faster.
Step 1: Check Power Supply
If your sewer camera is not turning on, start with the power source.
Check:
- Battery charge level
- Power adapter connection
- Charging cable condition
- Power switch functionality
Common issues:
- Dead or weak battery
- Loose charging connection
- Faulty power cable
👉 If there is no power at all, the issue is usually battery or power-related.
Step 2: Inspect All Connections
Loose or damaged connections are one of the most common causes of failure.
Check:
- Soft video cable to control station connection
- Soft video cable to reel connection
- Reel to cable connection
- Spring to cable connection: Ensure the waterproof rubber seal (O-ring) is properly in place and tighten the connection securely until fully sealed.
-
Camera head to spring connection: Ensure the waterproof rubber seal (O-ring) is properly in place and tighten the connection securely until fully sealed.
Look for:
- Bent pins
- Dirt or moisture
- Loose fittings
👉 A poor connection can cause no signal, flickering image, or intermittent failure.
Step 3: Test the Monitor & Controls
If the system turns on but there is no image, start by checking the monitor and controls.
Check:
- Is the screen black or blue?
- Are buttons or keyboard responding?
- Is brightness or contrast set too low?
Possible causes:
- Screen damage
- Internal display issue
- Control board malfunction
👉 If the screen is on but still not showing an image, the issue is likely coming from the camera head or cable, not the screen itself.
Step 4: Inspect the Cable

The push cable is critical for both movement and signal transmission.
Check:
- Kinks or sharp bends
- Cuts or worn areas
- Signal loss when moving the cable
- Cable connector condition
Common issues:
- Internal wire damage
- Signal interruption
- Reduced pushing performance
Connector warning:
Inspect the cable connector and spring pins carefully.
If the metal rings on the connector appear scratched or worn, it is often caused by damaged, stuck, or misaligned spring pins. This can lead to poor contact and signal issues.
👉 If the image cuts in and out when moving the cable, the cable is likely damaged internally.
Step 5: Check the Camera Head & LEDs
The camera head is one of the most exposed components and often fails due to wear or impact.
Check:
- Are the LED lights turning on?
- Is the image visible but dark?
- Is there water or debris on the lens?
Common issues:
- LED failure
- Dirty or scratched lens
- Water damage
👉 If the LEDs are off or weak, visibility will be affected even if the camera is working.
Step 6: Check Recording & Storage
If your system is working but not recording, the issue is usually storage-related.
Check:
- SD card or USB is properly inserted
- Storage capacity does not exceed 32GB
- Correct recording mode is selected
- Some systems have multiple video channels (Video 1 / Video 2). The correct recording mode is on Video 2.
- File format is supported by the system
Common issues:
- Corrupted SD card
- Incorrect formatting
- Faulty or loose USB/SD port
- Dirt or debris inside the port
👉 Try using a different SD card or USB drive, and format it if needed before assuming a system failure.
When Should You Repair or Replace Your Sewer Camera?
After diagnosing the issue, the next step is deciding what to do.
Repair is usually the best option when:
- The problem is isolated (kinked or worn cable, damaged connector, broken screen, or unresponsive keyboard)
- The system still powers on
- The cable or camera head can be replaced
👉 Most issues can be fixed by replacing a single component, thanks to the interchangeable design of the system.
Replacement may be needed when:
- Multiple components have failed
- The system has severe water damage
- Repair costs are close to the price of a new system
Important note: If the camera head is damaged or LEDs are not working, you usually only need to replace the camera head, not the full system
Frequently Asked Questions
1. Why is my sewer camera not working at all?
If your system does not turn on, the issue is usually related to the battery, power supply, or internal wiring. Start by checking the charger, battery level, and power connections.
2. Why is my sewer camera turning on but not showing an image?
This is typically caused by a loose connection, damaged cable, or faulty camera head. If the screen is on, the issue is usually not the monitor.
3. Why does the image cut in and out when I move the cable?
This usually indicates internal cable damage or a worn connector. Movement affects the signal, causing the image to flicker or disconnect.
4. Why is my sewer camera not recording?
Most recording issues are related to the SD card or USB device, including incorrect formatting, unsupported capacity, or a faulty port.
5. Can I fix my sewer camera myself?
Yes, many issues can be fixed on-site, such as:
- Replacing cables or camera heads
- Cleaning connections
- Changing SD cards
More complex issues may require professional service.
6. Do I need to replace the whole system if one part fails?
No. Most Forbest sewer camera systems use interchangeable components, so you can replace only the damaged part instead of the full system.
7. How do I know if my sewer camera cable is damaged?
Common signs include:
- Image cutting in and out
- No signal
- Visible kinks or wear
If the issue changes when moving the cable, it is likely damaged internally.
8. How long does a sewer camera system usually last?
With proper maintenance, a sewer camera system can last several years. Lifespan depends on usage, handling, and regular inspection of key components like cables and camera heads.
