Canon 430EX II flash... batteries A-OK. But flash doesn't fire... tried pilot... doesn't work

Possibly the sync speed set the camera on 1/80 sec and retry

Try mounting the flash on your camera, turn both on and reset your camera to factory default settings in your camera menu settings.

Return it as faulty goods to the retailer

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

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.

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

The conceting piece of the Flash has cracked when i dropped it, is there any thing i can do to repair or exchange it?

I have a 430ex and S5, I don't think the zoom head will move without being mounted on a camera.

If the flash test fires ok, then it should be fine.
