Can Neon Signs Be Repaired?

We explain the process behind repairing an LED Neon light, should any repairs or adjustments be required.

Yes, our custom LED neon signs can absolutely be repaired — it all just depends on the issue.

Unlike the traditional glass and gas neon that can be time-consuming and provide heart-stopping repair costs, our signs are typically much simpler to repair, and considerably cost-effective — or free if under warranty!

If you’re enquiring about repairing a traditional gas neon, we unfortunately no longer offer this service. However, we’d be more than happy to make you a new, friendlier LED neon sign!

Some typical issues with LED neon lights that require repairs include short-circuiting, loose connections and faulty transformers. All of these issues are covered by the 2-year electrical warranty included on all of our custom signs.

Repairing a short-circuit

Repairing neon light short-circuits is fairly straightforward.

We first identify this issue by powering on the sign. If the transformer’s status light is flashing, this generally tells us there is a short in the sign. Occasionally, this could have been caused by an electrical surge while the customer had the sign connected, which is outside of our control.

To repair the neon sign, we’ll systematically begin removing cables in the sign to isolate the short-circuit. When found, we will simply re-cut a new letter (or section) of Super Rad LED Neon, remove the faulty LED neon, and replace it with a brand new section.

This short video here focuses on the repair of a defective part of the Je t’aime sign.

Repairing loose connections

Occasionally some parts of the LED neon sign or the entire sign will no longer illuminate unless the cable or wire going into the section or sign is moved or jiggled.

This is due to either rough treatment during courier, vandalism of the sign, or insufficient quality control prior to dispatch.

What we typically do is remove the loose cable, widen the ports it needs to fit into, replace the cable or wire, and place it deeper into the port than before and use a sufficient amount of fast sealing glue to hold it safely in position.

After repairing the neon light, we will then keep the sign illuminated for 2 - 3 days to ensure the issue is fully fixed before handing the sign back to the customer.

Replacing faulty transformers

Sometimes, transformers we get from our certified supplier do not last as long as expected. We replace these rather than repairing them like we do with the neon signs.

On occasion transformers can last 10 - 20 seconds from the first time they are powered, and seemingly refuse to power again. Also, if a sign transformer is powered perpetually with no switch-off periods, it can overheat and die. This can typically happen after 1-year of endless use.

To diagnose this, we check the status light situated on the transformer. If it is not illuminated, then the transformer has perished.

In this case, depending on the warranty, we’re more than happy to send you out a new one. Our neon light warranties are there for you, even when repairing isn’t an option.

Alternatively, they are also available for purchase from your Radikal representative if the issue is deemed to have happened through misuse. Get in touch via and we’ll see what we can do for you.

No neon sign issue is ever something we can’t repair or replace!
