430ex speedlite not working

Hi I have a Canon 430ex only about 7 months old, while using it, it made a loud bang (max flash sort of noise ) after which it would not work, the flash gun still makes a charging noise which continues, but will not reset / flash any more. And the batteries get very hot very quickly. Any idea whats wrong and what can I buy to fix it, It's not been dropped or got wet at any stage HELP please

Buy the 550EX, it's cheaper

Master /or Slave = 550
Slave = other

Make sure it is not set to manual 'M' on the display. To get it to shoot in ETTL (Through the lens) press the mode button and it should read ETTL in the top left corner. This then means that the light is metered thorugh the lens and you are not relying on the manual settings.

Hope that helps. I had the same problem when i first got my.
By the way a brilliant all round bit of kit. I have traveled the world to some fairly extreme temps and got it wet (Rain, humidity, sea spray to deserts and serious dust) All good.

Good luck

SOURCE: can't find the serial number on my 430EX

This is where I found mine:
It's a 6 digit number located on the top half of the flash (the bit that tilts backwards and forwards). On one side it says Speedlite 430EX II, on the other side there are a few symbols and underneath is the serial number engraved on the plastic.
I also found it printed on the warranty card that came inside the box.

  1. Make sure the trigger you are using is compatible with digital flashes.
  2. isolate the smaller contact so they do not "short out" on the trigger.
  3. make sure the trigger is working and will fire other flashes

SOURCE: speedlite 430ex, pilot light on,

Typically, it means your batteries are low but I am sure that you know that already.
The next cause is a mechanical failure. The flash has capacitors that **** up the battery power until they have a full charge and the trigger the ready light. Therefore, if your batteries are good then it is likely that the capacitors are disconnected or have failed. Eitherway, you will most likely have to send it out to a Canon service center. You can find service centers at www.canonusa.com.

I hope this helps. Good luck!

Check the contacts on both the camer and the lens. I usually clean mine with methylated spirits or isopropyl alcohol. I have to do this every 3 months or so as dirt or even oils from your hands can stop the contacts from working properly.

My canon speedlite 430ex does not charge up, batteries are new and rear screen works/lights up any ideas?


Sounds like an internal wiring circuit problem. It's strange that the screen lights up but the flash doesn't charge. You should probably get it checked by Canon.

Just got a Canon 7D. Attached my 430EX to the hot shoe and it won't fire. Tried new batteries and checked the contacts, and it still won't work. Put th 430EX back onto my Rebel XTI, where it has always...


Make sure you using flash grade batteries and not rechargables. try energiser ultra or litiums or duracelll plus but nothing else. if the charge light is not coming up then most likely batteries. I would take it to your local camera shot and test your 7d with one of thier 430 just to make sure the hotshoe didnt short out the flashgun

My 430 is making a buzzing noise then it flickers


the buzzing noise is normal for that model .. first it makes noise as it charges and maintains the capacitor then when it auto focuses ..
here is a discussion of your speedlite model and the buzzing it produces
