Is Your Plumbing Camera Going Blue and No Signal? Here’s How to Stop

Intro

Sanyipace Plumbing cameras are essential tools for diagnosing underground pipeline problems, saving time, labor, and guesswork. But when that all-important screen suddenly turns blue and no signal, it’s more than just an inconvenience — it halts your entire inspection process. If you've encountered the dreaded blue screen of mystery on your sewer camera system, you’re not alone.

🔍 What Is a Blue Screen and No Signal on a Sewer Camera? Why Is My Plumbing Camera Showing a Blue Screen and No Signal ❓

In this blog, we’ll show the most common reasons for blue screens and no signal issues in plumbing cameras and, more importantly, share practical solutions to get your system back to work.

A Blue Screen and No Signal on a Sewer Camera, don't like the “Blue Screen of Death” in computers, a Blue Screen and No Signal on a plumbing camera usually indicate a disruption in the video signal. Instead of displaying live footage from the camera head, your monitor displays a blue screen and No Signal. In many cases, this points to a connectivity issue. As a result, it becomes impossible to monitor real-time visuals during an inspection. Eventually, without resolving this, the inspection process can be severely delayed. Therefore, identifying the root cause promptly is essential.

⭕Common Reason for Plumbing Camera Blue Screen Issues⭕

1. Loose or Damaged Accessory Connections

Plumbing camera systems rely on a sewer coil, connection cable, and camera port to transmit both power and video signals. When any of these components—especially the cable—is loose, frayed, or internally broken, it can instantly kill the signal and trigger a blue screen.

🛠️Check:

Inspect all accessory connections based on the provided pictures to ensure nothing is loose or damaged.

✅Solutions:

• Reconnect all accessories securely
• Replace any damaged parts 

2. Sewer Camera Head Issues

Operating under harsh conditions, such as exposure to water, mud, corrosion, and physical impact, the camera head is vulnerable to damage. This is a common cause of a blue screen and loss of signal.

🛠️Check: 

1. Examine the lens for cracks, dirt, or missing glass

2. Inspect the pin and waterproof ring for deformation or absence

3 . Confirm the spring isn’t suffering from poor contact

✅Solutions:

• Dry the camera head if moisture is present
• Replace the camera head if damage is confirmed

3. Plumbing Camera Coil Damage

The sewer coil is responsible for both power and signal transmission. During pipe inspections, it may be subjected to bending or impacts, which can result in internal damage.

🛠️Check: 

Look for visible kinks or breaks in the coil, and inspect the circuit board for signs of water ingress, wear, or loose connections

✅Solutions:

• Clean the coil’s circuit board with alcohol wipes and ensure it stays dry
• Replace the sewer coil or its circuit board if necessary

4. Faulty Meter Counter

The drain Camera with meter/foot counters helps accurately measure the cable length inside the pipe. If this feature malfunctions, it can interfere with the camera system’s feedback.

🛠️Check:

Check if the meter counter has fallen off and observe if it fails to measure cable length correctly when pulled.

✅Solutions:

• Replace a meter counter

5. Invisible internal circuit problem

The plumbing camera has no obviously damaged parts, and all accessories are new, but there is still a blue screen and no signal. What should I do?

🛠️Check:

Use a multimeter to test whether there is voltage inside the video cable, sewer coil, and meter counter (take the F5100DJKABTX sewer camera with a coil diameter of 0.28/7mm and a coil length of 40m/165ft as an example)

⭕Start by testing the video cable

⭕Test the sewer coil⭕

⭕Test the meter counter⭕

✅Solutions:

• If there is no voltage inside the video cable, please replace it with a new one
• In case the sewer coil shows no voltage, consider replacing it with a new coil
• Should the meter counter lack voltage as well, a replacement meter counter is recommended
