Neon signs have been used in eye-catching displays for over a century. With their retro charm and mesmerizing glow, neon displays have become an iconic symbol of a city’s bustling nightlife and entertainment. The use of neon in signage has fluctuated in popularity since its debut in 1910. With the increased availability of alternatives, such as fluorescent and LED lighting, the widespread use of neon signs began declining in the 1960s, surging again in the 1980s. Today, it’s safe to say that neon is coming back to life, with many consumers finding themselves attracted to the warm glow of a classic neon sign.
There’s no doubt that vintage neon signs are making a comeback. Today’s neon lights have protective features to prevent damage and breakage, making them more durable than ever. However, the passage of time and exposure to the elements can still take a toll on these luminous beacons. Understanding the intricacies of neon light repair can help preserve their brilliance and allow them to stand the test of time.
Neon sign repair involves diagnosing and fixing issues like broken tubes, connections, or transformers, often requiring specialized skills to restore the sign’s functionality and appearance. Professional services can replace damaged tubes, repair high-voltage problems, and ensure the sign glows brightly once more.
Let’s take a look at neon sign repair in a little more detail.
1. Inspection
The first step in restoring a neon sign is to identify the issue. First, inspect the sign for any visible cracks or breakage of the glass tubes or electrical components. Cracks or leaks in the neon tubing can compromise the sign’s ability to glow. Broken or damaged wires or connections can prevent the sign from receiving power. Problems with the transformer, which supplies the high voltage required for neon signs, can result in flickering or dimming. Thoroughly assess the condition of your sign or seek professional assistance if you’re unable to diagnose the issue yourself.
2. Safety Precautions
Due to potential hazards such as high voltage and broken glass, it’s essential to prioritize your safety. Before undertaking any repairs, adhere to the following safety precautions:
- Turn off and unplug the sign to prevent electrical shock.
- Wear protective gloves and eyewear to protect against sharp glass or electrical hazards.
- Use insulated tools when working with wiring or transformers to avoid accidental electrical contact.
- Avoid skin contact with neon gas.
- Consider hiring a professional electrician or neon sign technician, especially for complex repairs.
3. Repairing the Damage
Once the complexity of the damage has been evaluated and all necessary safety precautions have been taken, you can begin to repair your neon sign. Here are a few common repairs:
- Tube Repairs – Begin your repair by carefully removing the old neon tube from its supports, using pliers or a tube cutter, and detach it from the electrodes. Clean the ends of the remaining glass tubing and the electrodes thoroughly to remove any residue or debris. Insert the new neon tube into the electrode, using a welding torch to heat the tube and electrode until they fuse together. Ensure the new tube is correctly connected to the power supply or transformer. Twist the wires securely and slide the electrical boot over the connections. You may need to refill your tubing with the correct gas blend before resealing the tubes.
- Electrical Connections – Replacing or repairing damaged wires is essential for restoring power flow to your sign. To repair electrical connections, start by cutting out the damaged section of wire using wire cutters. Next, strip the insulation from the ends of the wires using wire strippers. Twist the wire ends together, then solder them securely using a soldering iron. Slide heat shrink tubing over the soldered joint and heat it to secure the connection.
- Transformer Replacement – A neon sign transformer is used to power neon signs by increasing the standard household voltage to the high voltage required for the neon gas to glow safely and reliably. If a transformer is damaged or faulty, it’s generally more cost-effective and efficient to replace it with a new one. Replacing a transformer on a neon sign can be very dangerous, due to the high voltage involved, potentially leading to electrocution, burns, and even death. Only trained and experienced professionals should handle neon sign transformers.
With the correct tools and knowledge, you may be able to make simple repairs on your neon sign yourself. However, please consider the complexity of the damage before attempting a DIY project. Most neon sign repairs require specialized skills, careful handling, and safety precautions. In particular, older neon signs can present unique challenges, requiring a delicate touch and specialized knowledge to restore.
