Question about Canon Cameras
Posted by Anonymous on
Stop using the flash immediately and don't open it. The capacitor in camera flash can store enough energy to kill you if you make contact with it!
You have a defective flash and it needs to go into Canon for repair. There's not anything you can do to repair it yourself.

Thanks for offering the help.
I fixed it by just sitting down and going through every setting through trial and error.
A huge pain in the rear end. I got lucky and figured it out.

It is very dangerous though... [referring to Alexander's solution]... I've been shocked more times than I care to really admit, and that cap can cause some serious damage. Be careful!

I just got the 580 and had trouble with it blinking all the time, the bounce card was out about a mm and I did not realize it, once that was pushed all the way back--voila.

Most likely that Capacitor has "Gassed" as we say. It is now destroyed, however usually too the Driver Semiconductors "Blow" as well. I have seen this before, it is not uncommon. An enormous amount of energy is stored in this capacitor and circuit, and they often fail in an explosive manner.
What you need to do, is find a Canon authorised servicing center, contact your local or head office of Canon, and inquire as to a local repair center.
Now when you take the Flash in for repair, please ask for a 'Quote" before allowing any repair work to commence, this then will allow you to make an informed decision as to repair or replace.
It is hard to give an exact cost but I would expect, that around $80.00 to $125.00 for the basic repair, would be about right for a repair. BUT depending on what exactly was wrong, it could very quickly escalate.
I think you may find, that the cost of repair, may even approach, the cost of a new unit? This is also why getting a "Quote" is beneficial.
However if you can desolder and solder, could obtain the EXACT Rating and Value Capacitor and Semiconductors, (read ALL damaged bits) and were prepared to do a little work, it is entirely possible to repair this unit oneself. but be very careful when doing so, as flash guns can give a very very nasty "Bite" (speaking from experience :) lol)
