The neon signs have an almost universal appeal, and many have been rescued from their working lives to serve as pieces of art in homes and establishments around the world. The neon signs can be delicate, and vintage neon signs, in particular, often have at least some damage in need for restoration. The neon signs are high voltage, running at between 5,000 and 12,000 volts of electricity. With this in mind, repairs should only be attempted by someone comfortable working with the electrical wiring. With the popularity of new and old neon signs, spare parts are available with a little research for your specific sign.
- Determine if any of your neon tubes are broken or broken by gently swinging the tube. If there are cracks or breaks, remove that section of the pipe by unwinding the mounting wires with your fingers or needle-nose pliers. Replace the part with a new tube section ordered to match the old one.
- Test the transformer unit to see if the power is flowing through the transformer, and it is reaching the pipeline, or if it has failed. Disconnect the wire transformer leads from the mounting tube by removing the outer rubber cover, and gently unwind the wires that are stranded together to make the connection. Engage the transformer until a piece of pipe that is secure is not damaged. If it does not turn on, then a transformer is not the most likely cause, and a replacement will have to be ordered.
- Check the cable for any signs of wear, wear, or damage. It may have to be replaced, and many are available at neon supply companies. In the field of neon, it is an economical repair to do, providing a new cable is designed to carry the voltage that your sign requires.
- Illuminate the neon sign by having a cut repair shop, then refill the neon tube with fresh neon gas, and then reseal the tube. This is sometimes better, or not expensive, the solution of throwing an attenuated signal or a hose.
Tips and warnings
- The repair process can lead to differences in lighting because most of the tube has low phosphorus levels. In this case, it could be better to replace the entire tube.
