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.
takeonparis: Don't worry... I'm not thin skinned. I'm also right. Tamron has nothing to do with anything. The Yongnuo flashes are consistent in their inconsistency. You can order a couple new from Amazon right now. Maybe they'll. Work. Order two more. Maybe one won't. Check out the customer reviews. Mine is a dream. There's only one explanation if two identical products don't function the same. They're NOT identicle. Unless you have another explanation...

jrhodes1029: Bro its jason tood the 2nd robin tim drake is the 3rd ZedZedskiGaming: I find better temperature results if the intake is in front and the exhaust are on the back and top case (on the top water cooling radiators with push airflow). Maren: Kann sie überhaupt noch atmen,essen und so? SAVAGE 4LIFE: I know its a little late to comment but I just got one today and taking the cord out of the drone and the red cord got striped down to the wire Daniela Libon: Hi, have a question for you. so, do you see any difference in the maneuverability of the b-agile regular and the b-agile 4 ?
