If you have the camera on continuous then it may be that the charging is not keeping up with the shutter. Check the recycle time on the flash and compare with the burst speed on the camera. The burst speed on the 5D is fairly rapid.

Load 4AA with Energizer Lithium Batteries.
Set 580EX II's function to 12-0 and 05-0.
Make sure 5D's is not set to HSS.
No white dome parked on flash.
No bounce.
Set camera to "M" with max sync if you like, but 60 is fine.
Set F-Stop no greater than F5.6
Set ASA/ISO no lower than 200 but not over 1000.

If you need more assistance, contact Alzo Digital, CT, USA.
Asks for service & repair from ATG.

The capacitor (neck) is no longer hold a charge or charging circuit is going out on a extended breaks.

Save your money and buy ATG's Godox TT685c.
If you buys two, then you got ATG wireless radio ETTL II flashes.
It would cost over $1,000.00+ USD to buy two Canon 600EX II-RT just to do the same with two ATG's.

Hi John,
If your problem has not been fixed or a solution not found yet then you may consider this. Flash units are built with many tiny parts; thus, when a single component malfunction, it will render the whole unit useless. You mentioned the pilot light is not working - that indicates that power is not flowing through the unit.
Check the filament of the unit - if you notice some brownish stain on either end of the tube, it indicates the filament has burned out. Changing the type of batteries won't make any difference.
the only option you have now is to service the flash unit

Are you sure those are not pre-flashes being sent out?
What mode are you in, Master, if so it is sending pre-flash to other flash.

Just a guess work.
This may be caused by a mechanical fault. A dislodgement of an electronic component that is hanging loose. When the unit sits up-right position, the part may probably slips down, breaking contact with the circuitry but it can maintain contact with the circuitry in every other position.You could open up the unit and check to see if anything is loose.

A good possibility is the zoom head is causing the clicking sound. As we zoom the flash, the inside of the head moves to the back and forward. Gently tap it a few times see if that helps. My guess is it needs servicing.

This will come on if you manually activated it on the back of the flash. It's for the times when you want to manually provide wide or tele coverage.

be careful. examine the flash for physical damages. if it appear to be intact, you could try turning it on and see if you can fire with the test button. remember, this flash is high-voltage. do not attempt to fix it yourself. if it's not working, you have to service it.

does it have the pilot light on? does it make any noise? it sounds that you have to repair. I dropped my 580EX II once and the flash head partially came off. still works, but i need to get it repaired :)

red light (pilot light) means ready to fire, unless you referring to something else.

Canon SPEEDLITE... | Answered on Mar 04, 2015


first thing to try is fresh batteries. i'd recommend trying both rechargeable and alkaline.

The manuals for the 580EX and the 430EX say the following under "Reverting to nnnEX Default Settings": "When nnnEX is attached to an EOS camera equipped with a button, you can press it to revert the xxxEX's settings (except custom settings) to the default.

Hello,
When you manually zoom does it make the sound, or on the camera? One thing to try is change out the batteries, maybe there is not enough juice to work as needed. If doing that does not help, then I would contact Canon; the flash may need repair.

Don't. Dangerous charges remain in capacitors and can kill you.

Canon SPEEDLITE... | Answered on Sep 07, 2014


If resetting the camera to factory default settings WHILE the flash is mounted on the hot shoe and turned on doesn't help, you may have physical damage/failure with the flash and it will need to go in for repair. This sounds likely if you've had an ongoing problem since you got the flash.

You could also try checking the ETTL sensor to make sure it's not damaged or blocked by lint, check the flash on another camera to see if the problem persists, and check the hot shot mount on the camera and the flash to make sure they're not damaged and solid.
