430 flash bulb burnt out: HELP!

I was using my flash. Then nothing. Red light is on. I hit it and i can hear capacitors trying to discharge but no light. I did hear a louder then normal POP when the flash went of last. The annoying this is the flash is only a little of a year old or so. Pretty sure it is the bulb that is burnt out. I have seen stuff hinting that this can be replace DIY but I can't seem to find a thread or anything online that shows how to do this.

Please help with any info to fix this. It is being run on standard AA bateries. not battery pack or anything. thanks

Hopefully someone answers this and it's an easy fix. I posted about bulb life on a different forum and no one knew much.

Good luck,
dan

I would think that replacing a bulb is possible and probably fairly easy but I have never done so myself, so I am subscribing to see what comes up.

Here's the for replacing the tube on the 580EX for some ideas...

Great tutorial and looks very doable.

Make sure to heed the warning in the post. Even a partially charged cap can give a significant zap. If its clear which leads come from the cap, it can be slowly discharged with a high value resistor.

Quote from link....
"Disclaimer: Just a word of warning. The capacitors in the flash can hold its charge for a LONG time. And you can get a HUGE shock from it. You should google how to discharge them. I left the flash empty for 2 weeks, and I still got 2 tiny discharge which I felt."

I just oredered the bulb from canon for 33 dollars. almost 1/4 the cost of the flash. ohh well. Just really annoyed that the bulb went out that quickly (only owned the flash for a year and a half or so. It does have about 5-8k pops or so on the flash. What is the best way to discharge the cap? I know when i did car audio system installes and we would discharge caps, well i did not do that, but i watched another guy use a hanger and short out the cap to discharge them. LARGE SPARK. does that hurt the capacitor to discharge them like that? is that doable with the 430?

Not really. We use to discharge color tv tubes like that before working on them. As someone said earlier, these guys can hold a charge for quite some time.

I use this to bleed caps in vacuum tube guitar amps and have used it for flash heads. Simply a resistor that drains the charge slowly. The one I used is about 47kΩ 1/2w. Could be higher in value, just would take longer to drain the cap. The wires at the very ends of the flashtube should be the leads from the cap, unless Canon did something funky. The smaller wires fire the tube. Be absolutely careful not to accidently contact something else on the circuit board while attempting to drain it.

I would advise not to directly short the cap, unless you're used to having something like a small firecracker go off at your fingertips

I Have the part for the flash. Well what canon sent me does not look like the part that was in teh 530 ex fix. now i know this is a smaller flash. but.... what i got looks like a flash bulbe with a bunch of wires coming off ot if. It looks like i have to solder the wires on which should not be a problem, i hope, i have soldered stuff before.

I have figoured out how to take the top part of the flash apart (where the bulb is) i have the case off the top i mean. I can not figure out how to removed the flash from the white part that holds the flash assmeble in. i have removed all the screws and can't figoure out how to get the flahs part out???????????? who has done this before. Also i can't figure out how to get the the capacitor to discharge it safely?

I found a post online that was supposed to show and exploded view of 430ex. but link is dead, anybody else have this?
