smarsh599: The problem with this is undoubtedly batteries. I took possession of mine two days ago and was going to return it until a photographer friend told me to buy 4 x heavy duty rechargeable Duracell NiMH batteries and a high speed charger. Did that and put the batteries in and no further problems. Also to ensure that none of the charge leaks out of the batteries when they are left in the flashgun, even with it off, I cut a piece of thin card and put it between the batteries and the lid of the battery compartment to break the connection (just in case of a discharge). All works perfectly now.
Julian Spira: on my one the light stays green and after 20 seconds it shuts down saying power low, been tho they're freshly charged batteries that work fine on my other flashes
Pablo Guedes: this problem is caused by a cable that make the zoom on the head work, in may case the flash don't zoom and after a few clicks the red light turn green and don't work. i just put the cable in the right way and the flash work's again. the head of this flash rotate in infinite way and the cable goes out of the right way and thats the problem.
angelisone: had the same problem with my canon 600ex-rt.
Marcio Caus: I have the exact the same problem on my new yongnuo YN568EXII. Did you find the problem?
Aviectus G.: just bought it, when i installed the batteries one of them exploded ( brand new ) and liquid was leaking from the inside. Also the battery made a boiling sound. i tried with other batteries and it wont turn on, also you can hear loud noises like "puff" "puff" when i turn it on
Steven jean pierre: Yongnuo YN565EX for canon 40d auto function? is good
TheKkd123: freaking bullet piece of crap! Can't freaking believe it. I had it for less then 1 week with around 160flash fire . And now it's dead !!! UNBAfreakINGBELIEVEABLE
Giorgio Cesarini: 2 options;
1) your 565EX its for nikon E-TTL and not for canon , probably a mistake in shipping 2) the hotshoe resistor is not triggered right
Harry Sanderson: It's sounds like the flash tube has been broken or is non functional. You can buy a new one on eBay. :)
Thomas Cole: Mine does the same thing brand new right out of the box.
Daniel M (FunnyMusicGermany): Hey, i am a german, my Englisch is not so good, sorry.
The "Yongnuo YN565EX" - is for Nikon Cameras (i-ttl). Not for Canons :)
Martin Pištěk: I have same problem! What i should to do?
Frank Benjamin: I had the same problem and this fixed the issue. for yn560 its the faulty capacito. For the 565ex, its the faulty ignition coil.
nishchay kumar: its the shoe mount....there are replacements for it on ebay.
1841skipper: IKEA batteries????
malvinmalvin: This may be a little late, but I think it's the capacitor in the flash head. I had some problems with a 565EX aswell, but it turned out to be the ignition coil. When I first sent an email to yongnuo, they said it's mostly the capacitor when the unit doesn't fire at all.
The capacitor is a 630V 473K, i.e. 47nF.
If that doesn't fix it, consider replacing the ignition coil, they have a tendancy to short out because of bad insulation. ign.coil: 6kV TC-36 (ebay) google the rest
Marcel Klein: I think it is a Flash for the Nikon camaras!
takeonparis: In that case you just said the exact same thing I was saying... but in a different way. The components of any two Yongnuo flashes could be completely different (although you're arguing that the components could simply not be tested, I would say there's that... or they could not even be the same components at all.) Both solid theories. Unless they let us in the lab, we'll never know.
ZeroG84: Well, if quality control is not up to par, when compaired with the distant Canon cousins? 565EX and even the 560 (that I own) are actually powerful flashguns. If the manufacturer skimps out on checking and testing each of the components they buy in bulk, then a more powerful unit could be less reliable and more easily burned out. 460 and 462 I have are less powerful, but then again, you don't hear anything bad about them. Same amount of power going in and less light coming out = no burning.

Dwyte James: it's a very distilled version of the book... more is explained in the book and although slightly depressing a more believable ending is done Иннокентий Котов: Купил его пару часов назад, сейчас заряжается. В комплекте был usb кабель, наушники, гарантийный талон и инструкция по эксплуатации. Обошёлся мне он в 990 рублей. Надеюсь, прослужит долго. Abdullah Alzoubaidy: Tara reera tara reera aywaaaahh !
