Send the flash back to canon for Service this is not something that can be fixed in this forum. Do not use the flash the burning smell indicated a potentially dangerous problem and fire hazard.

Canon 550 ex speedlight - flashes okay. Won't sink with 60d (tried different cameras at dealer - same problem) Camera is okay .


Bruce,
Try these steps:
1. Set camera to manual2. Set shutter to 1/60
3. Set aperture to F5.6
4. ASA/ISO 200
5. 550EX on hotshoe
6. Do not set on slave or master
7. Turn on flash


Display must shows, ETTL.
If that doesn't work, you have to use the flash on manual.
Some of this model will not work fully on ATG Canon EOS-1D C, ATG Canon EOS-1D X IR, Canon EOS-1D X/60D/T4i because this flash is over 20 years old.


Unless you would want it to be modified by me.
But that can be costly when you can get the 580EX II for less than $425.00 USD.

My canon 580 EX II stops firing even with new batteries


You must disable the 580EX II form using the 4AA.

4AA must be needed when using hv power pack.

Just let the 4AA use & display the LCD panel.

More help, repairs & troubleshooting send me an email.

I have been using my Canon 580ex ii with my Canon 5d mark ii. It will not fire at all now. I also tried my old 420 ex speedlite and it will not fire either. But, they both work on my Canon 40d.


You can actually set the external flash not to fire in the menu settings of your camera. Check there or try mounting the flash on your camera, turn both on and reset your camera to factory default settings through your camera menu settings.

No. The rebel, or any digital canon camera requires the use of the EX or EX II series flashes.

Flash 550 lcd screen lighs up but will not fire the flash


$300. ? To REPAIR? Way out of line. Replace the unit with a similar flash or go for another brand. SUNPACK flash units are reasonably priced and the have models that work with Canon abd orher cameras.

Won't Work As Slave With Canon EOS 400D


Speedlites with the suffix "EZ" are never compatible with the digital EOS line-up. All models that do work are named "EX" (420, 430, 550, 580EX et al.)
