p.1 #1 · 430 II flash head blown


I was setting up for a portrait session today when the flash head on my 430II blew. It was on a Yongnuo ETTL trigger on top a light stand and had a fresh set of eneloops in it.

I wasn't firing the flash or testing it at all. It was just sitting there when I heard a loud pop. I went over to the flash, noticed the smell of smoke, and immediately turned it off. When I removed the batteries, they were hot to the touch, but nothing else seemed to be amiss. The flash would actually turn back on, but the head would not charge. The indicator light stayed off and would not show green or red.

After I got home tonight I tested the batteries and all seemed to be putting out normal "fully charged" voltage. There was nothing to indicate they had overcharged.


Any idea what happened here? Any idea what Canon will charge me to fix the flash?

That's unusual, especially considering you weren't actually firing the flash at the time, from your description it sounds like you hadn't been firing the flash rapidly in the lead-up to failure.

It's odd that the batteries were hot, that indicates high current through the batteries, perhaps there was a short-circuit within the flash (either before or after failure).

A flash failure can be caused by a high trigger voltage, but you weren't actually triggering the flash at the time (I assume you've used the Yongnuo triggers before without issue)

I expect that repair may be uneconomical, but you can always ask

Sorry I can't be more help

The triggers have been used many times before with no issues. It could have been a short circuit of some sort, but there was no debris or moisture inside the battery compartment. Maybe the flash malfunctioned internally?

Once the smoke escapes...it's all over...most of that smoke is, (was), stored in the charging circuit...

For me, Canon replaced the entire Auto Reflector Array for about the cost of a "level 2" labour + parts

All up approximately 2X the cost of a Sensor Clean

Sounds like a failed capacitor in the unit. If the capacitor becomes internally shorted, the batteries will continue to try to charge it and will get hot.

That sounds logical, I like that explanation

Just as an update on this, it turned out to be a corroded power supply... weird. Canon charged me a standard out of warranty labor ($89), plus shipping. With a CPS gold discount, it came to $62.30.

Well, $62.30 isn't too painful-sounding; much better than having to buy another 430 either new or used.

Any idea what would/could have caused this corrosion?

No idea... I bought the flash used so there is really no telling what caused it.

Just not like spending money on Canon.
But honestly speaking, they are good quality ones.
