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...
ZeroG84: No harm no faul. Fact of the matter is that even Yongnuo makes flashes that look like other stuff, they are actually very respectable when it comes to the new wave of electronics coming from China, and they were in PhotoKina 2012. check it out: ww.hkyongnuo. com Tamron gets their stuff assembled in China too.. etc. So it doesn't automaticly meen that the parts are out of some bin in some backalley. Don't live in the past my friend.
takeonparis: Meh... Also seems like you're kindof a pickle... But I'm not holding it against you. It's Youtube comments... so what anybody expect? Anyway, as I said IN THE POST YOU COMMENTED ON... I know it's Chinese. I own the damned thing and I bought it from China. That was the hint. Just accidentally wrote Japanese. But the fact that it IS Chinese means that... just because the thing has the same name and the same box... does NOT mean they are identical. Take any two Chinese knockoffs of anything apart...
ZeroG84: Well it seems you don't know anything about flashguns, or electricity in general. Firstly, YN is a brand from China. Not Japan. Canon is from Japan. Nikon is also from Japan. Second, if you have two identical flashguns and the otherone gives an error-signal, it is not the batterys that are at fault. This test was very well done and isolates the problem very clearly to the hardware or the software of the second 565EX.
Hope you got a new one in warrenty.
Kamal jun: Hello, are you familiar with "Photo SFXart Tricks" (google it)? There you can watch a nice free video showing how to make impressive photos. This helped Joe to create pictures that leave you with a jaw-dropping-effect whenever you take a look at them. Hopefully it will work for you as well...
wgsam82: Same thing happened to me. even the testing button not working. what a crap.
Please don't buy. waste of money.
canturgan: Try it in slave mode and see if it works and clean the hot shoe contacts.
deadoverlord: It must be some capacitor or transistor that burned down, if you know how to test these eletronic components you can do the repair yourself!
takeonparis: Yeah I know that actually. I have no idea why I wrote Japanese. Think I must've had a japanese lover at the time or something and that was on my mind hahahahhaa.
RMACMEDIAPRODUCTIONS: actually youngnuo isn't japanese, it's a company straight out of hong kong CHINA.
Tuan Mohd Mas'ain Tuan Mohd Azmi: OFF THE CAMERA FIRST BEFORE INSTALLING SPEEDLITE!
lameron smith: i got a god damn same problem. even the beep beep beep beeeeeeeeeeeeeeeeep sound..
its not the batteries problem i can tell u that,, cuz i test 10 of difference brands of batteries, it still doesnt work. when i press the pilot bottom to test the flash, nothing happen just like the vid above. i got it couple weeks ago and now it blew it.. WTF
did anybody know how to fix it. ton of thanx...
Canosa Fotooprema: It can be repaired and enhanced with new quality components in our service in Croatia. Also it is possible to send the defective flash from other countries to our service, and delivery back repaired flash
Jimmy Chen: im having the same problem, the flash only goes off once every now and then. like 1 out of 20 times. using 1.2v energizers, tried 1.5 alkaline batteries, same thing happens. anyway to fix it?
rodrigo morales: If u wanna use the flash like a professional dont use it in ETTL, use it in manual mode and learn to use it. I only use the ETTL when i get the flash of the camera and use it wireless but using always the flash in ETTL is like using ur camera always in auto mode just noobie
rodrigo morales: Even the canon would die if u fire it continious @ 1/1 or 1/2, i always use it @ a maximum of 1/4 but i really try not to, preffer to go on a 2000 iso using a 2.8 lens and going around 1/16, no flash will last if u use it @ maximum power in burst or continius shooting
Zion Brown: its porous to be an Ettl flash so if the camera needs full charge or half charge flash firing ,it should give it . its for what the made or not?!. so that the flash survive you need to rouven you pictures?
rodrigo morales: Ive been using it for like 10 months, works awsome and i do wedding photojournalism. Ive got two 580 exii and the YN performs as good as the canon, no complain about it
rodrigo morales: lol the canon flashes are made in china too lol
rodrigo morales: I cant disagree with u more, ive got one for almost a year and i havent had any problems with it, it works better than the canon 580ex ii, its a really awsome flash. You just gotta try not to use it @ max output continuosly because when u do so u overheat it, even with the canon original one
rodrigo morales: First of all ill recomend u to turn of the flash sound on the custom functions of it. Have you been fireing the flash at max output like 1/1 or 1/2 o even 1/4 too often, when this happens the flash overheats and eventually if u keep overheating it it dies.
peter kor: thanks a lot guy for the comments and the review - now i know i WONT BUY IT ! it looks like real chinas junk with problems !
Bernard Fernandez: Just only yesterday after i purchased it last july 2 it doesn't work now all the same situation my camera can communicate with the speedlite but it doesn't flash i even bought a rechargeable battery. I bought this in philippines by any chance is there any service center in dubai who can repair this
Zion Brown: What did you expect from a Chinese flash no QA 2 from 10 not working in all made in china stuff
Goertosing: You should buy it localy, from autorized seller with waranty. Price is more expensive than prices on ebay, but you will be sure that it will works good and have a waranty and service provided.
Ebay Yongnuo flashes are coming directly from factory and they are not tested before. They have a QC (Quallity Control) mark, but there is no quallity control with that models.
Goertosing: That is reason why Eneloop XX provide you to make more than 300 shoots without re-chargning, about 150 shoots with Duracel and about 50-60 shoots with no-name batteries. Eneloop have 1.3 V when they are full charged, and 1.2 till end of capacity, falls to 1.1 only when you discharge battery till end. Other batteries have 1.3V in begining, and falls to 1.1V at the half of capacity
Goertosing: Non sense!
If you can not see different batteries in video above, it doesn't mean that we were not test them all. Tested batteries: Sanyo Eneloop, Sanyo Eneloop XX, Duracel, Ansmann, Panasonic, no-name and other batteries. All new and recharged.
Voltage of new recharged AA battery is about 1.3V (not 1.2 as declared). When voltage falls to 1.1V - in that case flash will not works.
Goertosing: There is no matter if it is producted in January 2012 or in some another time. That are only phrases, non sense! We have 5pcs YN565EX for repair. Two were producted in 10.2011., one in 09.2011., one in 01.2012. and one in 03.2012.
You have YN565EX about 2 months of using and you tells that your example is good one? I will ask you after few months, or one or more years.
Goertosing: Flash bulb of YN565EX is very good, it will never blow.
Problem with Chinesse YN565EX is main transistor, capacitor, and ignition coil. Electronic components are undersized. Therefore, can not last long.
Sometimes, when the transistor burns out, it can burn out and the main processor. It can not be repaired because the processor is sealed with rubber.
In models that trade resellers in the EU, the transistors are built stronger to tolerate 6 times higher voltages and two times more electricity.
customlumina: was the flash bulb just blown?
saiduzzamanful1: Hi, are you familiar with "MagicSFXphoto" (just search on Google for it ...)? There you can watch a good free video showing the way to create brilliant pictures. It made it easier for Matt to take pictures that leave you with that jaw-dropping-effect after you take a look at them. I hope it works for you as well.
Matt Butt: OOOPS!!!!! i was looking at the wrong side, I found it , built dec, 2011
Matt Butt: Thanks, there's only one sticker with the serial number, CE mark 6v and made in china. I'm wondering now if I have an older one. Only had it a couple of days so I'll give it a good test. At least I got it from Amazon so I may have some comeback if it fails.
Thanks for your reply.
takeonparis: Twist the top of the flash. There should be a sticker on it with the month and the year.
Matt Butt: Hi, I've just bought one of these from Amazon but I can't find the build date on it, where does it say it on yours?
takeonparis: Forgot to add: Thanks for putting this video together.
takeonparis: I recommend this Flash. Build Date: ALL the flashes that were purchased in January 2012 had problems (see my other comment). Look on Amazon... look everywhere. All the bad reviews are from flashes purchased in January 2012. The initial batch from 2011 worked fine. Mine has a build date of 3-2012 and works fine. As for recommendations... If you have the money to get a 580 EX II, then just do that. But you can get two of these for the price of one 430 EX you'll always have a backup if repairing 1
takeonparis: Believe it or not I think it's the batteries. The problem is that you used the same set of batteries each time you tested. That's not a real test. This isn't a Canon product. It's a Japanese knock-off. That means that the internal parts probably aren't always the same. In fact, it could be the only similarities between those two flashes are their external appearance. I tested it with my own YN-565 and with my first set of batteries... it wouldn't even turn on. Tried with a set of Vartas.. worked
snapfhish: I don't recommend this flash at all!!! I had two and they both blew. The first one in the same day I received it and the second with in a few uses...
snapfhish: I would like to say this is not an individual problem. I had bought two of the yn565ex flash units back in january 2012 upon receiving the flash units one had stopped working after the third use . I had bought this on ebay and to make it worse the seller was non responsive long story short it took over 65 days to get a refund. they never replaced the unit . now three days after them refunding the $ my second flash has failed . I DON"T RECOMMEND THIS FLASH !!!
zack c: ""Just confirm with our technical department, this is an individual issue,"
...well, I had two of them, and they were both lemons!
Most people that own a camera are hobbiests.. If you put these flashes to work (at least a couple hundred pops every week for a few months), I highly doubt they will last 6 months. Now if you rarely shoot, they may last a lifetime! My vivitar 285hv's are almost 30 years old, extremely reliable, and they still work like brand new!
Eddie Meco: what was it
