Canon 580EX II Flash Tube Replacement Service
A loud pop followed by a dead flash is the classic sign of a blown tube on the Canon Speedlite 580EX II. We replace the tube for a fixed €80 — even though Canon no longer services this unit.
Symptoms
- Loud pop during a shoot, then the flash stopped working
- Flash no longer fires in manual or TTL mode
- No flash output at any power setting
- Canon service refused the repair because the unit is too old
If your Speedlite made a loud pop and went dead, a Canon 580EX II flash tube replacement is almost certainly the fix. The blown tube is a well-known end-of-life failure on this flash, and it is fully repairable: we replace the tube at a fixed price of €80, with free diagnosis and a 6-month warranty.
The symptoms
The failure is usually unmistakable:
- A loud, audible "POP" during a shooting session.
- From that moment on, the flash refuses to fire — in manual, in TTL, at any power setting.
- No visible flash output, even though the unit otherwise appears to power up.
If this matches what happened to your flash, the tube has almost certainly blown.
What causes it
The loud pop is the classic sign that the flash tube itself has burnt out. A flash tube is a consumable component: after enough discharge cycles it fails, and when it does, it fails for good. No reset, battery change or firmware trick will bring it back — the tube has to be physically replaced.
There is an extra complication with this model: Canon has very strict service policies for older products. Once any Canon product has been out of production for 7 years, official Canon service centres no longer hold spare parts and will decline the repair. That is exactly what happened to the customer in the case below — Canon turned the flash away. As an independent workshop we are not bound by those policies, and we can still repair practically all Canon products (and other brands too).
Can you fix it yourself?
Realistically, no. It is worth checking the basics first — fresh batteries, correct contacts, the usual resets — but if the flash died with a pop, none of that will help. Replacing the tube requires opening the flash completely and desoldering components next to high-voltage circuitry: a flash capacitor can hold a dangerous charge long after the batteries are removed, so this is not a DIY job.
How we repair it
A customer sent us a Canon 580EX II that had produced a loud pop mid-shoot and stopped working. He had first sent it to the official Canon service centre, which refused the repair because of the unit's age. Our technicians disassembled the flash completely to reach the tube, desoldered the blown tube and soldered in the new one, taking care not to damage the electronic components close by. The flash was then reassembled and put through our full function check, included in the price.
The result: the flash fires perfectly again at all power levels, both in manual and with Canon's TTL system. We repair plenty of other Canon gear too — see our Canon repairs.

Frequently asked questions
What does a loud pop from a Canon 580EX II mean?
It is the classic symptom of the flash tube blowing. Once the tube has burnt out it cannot recover — it has to be replaced.
Will Canon still repair a 580EX II?
Usually not. Canon has strict service policies for older products — once a product has been out of production for 7 years, official service centres no longer stock spare parts and decline the repair. As an independent lab we can still fix it.
How much does a Canon 580EX II flash tube replacement cost?
We charge a fixed €80, including desoldering the old tube, fitting the new one, and testing the flash at all power levels in both manual and TTL. Diagnosis is free.
Is it worth repairing a 580EX II instead of buying a new flash?
In most cases yes. The 580EX II is a robust professional flash, and a €80 tube replacement is considerably cheaper than an equivalent new speedlite.
