My neon light isn't working. Follow the Complete Troubleshooting Guide.

Whether you’ve just received it or have had it for some time, a neon sign that isn’t working can be a real source of frustration. And no matter whether you are a professional or an individual, your neon is something you’ve customized, ordered to your specifications, dreamed about, waited for, and now, you want to see it shine!

We are going to give you all the tips to understand the possible causes of your neon sign’s failure and find possible troubleshooting solutions. In this article, we will explore step by step the reasons why your neon could be out of order and how to fix it effectively.

1. Initial Diagnosis: Check the Power Supply of Your Neon

The first step in diagnosis is always the simplest. Make sure that:

• The neon is properly plugged into a functioning electrical outlet.
• The switch is turned on.
• The power cord isn’t damaged or cracked.
• The remote control has batteries (if you have one).

2. Visual Inspection of the Neon

Before proceeding with complex repairs, carefully observe your neon:

• Are there any visible signs of damage?
• Does the bulb seem intact?
• Do you notice any cracks or blackening?

Common Causes of Neon Malfunctions

1. Number 1: The Outlet!

This may sound a little "silly," but it’s the first thing to check. If your outlet isn’t working, you have no choice but to contact an electrician and/or find another location to install your customized neon.

2. A Faulty Transformer

Most often, an unusual buzzing indicates a problem with the transformer. Even though at MK Neon we ensure the quality of the materials we use and the accessories we provide, a failure can still happen. If your neon sign is still under warranty (remember, a 2-year warranty), we will send you a new transformer as quickly as possible. If your neon has exceeded the warranty period, still contact us. We will help you find a solution.

3. A Faulty Power Supply

Bad electrical connections or oxidized connections can interrupt the current flow. Things to check:

• Connectors
• Junction points
• Internal wiring

This is a common issue and one to be cautious about. No risks allowed; your safety comes first! Therefore, if you suspect a power supply problem, check the circuit breaker. If the issue lies with the power cables themselves, unplug your neon and contact us via the contact form, sending photos of the neon’s wiring so we can make a more precise diagnosis and offer you the appropriate solution.

4. Defective Tube and Worn-Out LEDs

LEDs are essential for the neon's operation. Over time, they may wear out or degrade. If you notice the ends of the neon blackening, it’s very likely that the tube is defective and your neon is nearing the end of its life. Signs of defective electrodes:

• Weak and irregular light
• Frequent neon shutdowns
• Discoloration noticed at the tube's ends

5. The Dimmer

Electrical fluctuations can damage your neon sign. An unstable transformer, unexpected surges, or even a nearby lightning strike can significantly weaken its electronic system. Similarly, sudden thermal variations are a major risk for premature deterioration. Indeed, sudden temperature changes can create mechanical stresses that gradually damage the tube’s integrity. To counter these issues, our waterproof models offer enhanced protection, ensuring optimal resistance to the harshest environmental conditions.
