Problem with Yongnuo YN565EX - not working

- There are two YN565EX flashes. One Canon 500D. Four bateries.
First I tried one YN565EX and it works. I used same bateries, and same camera, and tried another YN565EX - I can turn it on, but it won't flash. After it, I tried first YN565EX again with same bateries and it is ok.
What can be problem with this YN565EX?
It is new. I tested it after purchase and it was working for several shoots and just stop working suddenly. 
Авто/Мото
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
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
I had the same problem and this fixed the issue. for yn560 its the faulty capacito. For the 565ex, its the faulty ignition coil.
@ultralisk2005 thank you very much my friend! I also found the problem and it was exactly the same with yours. Will replace the coil when the electronics shop re-stocks it.
Thank you!
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
Forgot to add: Thanks for putting this video together.
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.
I returned one to my local dealer, like 1.5month old. No Flash Firing, sometimes rapid flash when try to shoot. I used it hard just before the moment it dies. 1/1 all the way and kaboom!
""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!
From the sales company:
"Just confirm with our technical department, this is an individual issue, we do not received similar or same feedback from our client before.
Currently, YN 565EX is one of our hottest flash in the market. At the same time, I will provide you one year warranty. Please rest assured use.

plus this:
"For our flash, we made a big progress and the quality was also better now."
Now quality good!!!!
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.
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.
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.
Yongnuo YN565EX for canon 40d auto function? is good
@markmaker3 whoever told you you need to turn the camera and flash off when removing it is lieing. The camera and flash are independently controlled. The point where they communicate is a simple electrial contact on the camera's hotshoe. Voltage only comes into play when using older flashes that have higher voltage outputs then the camera can handle. 99% of the flashes you pick up will not harm the camera.
I have same problem! What i should to do?
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
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?
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?
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.
same here. did you get it to work? its been 2 months since the video has been uploaded.
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
@ultralisk2005
Hello, I have the same problem, I saw the pictures on the blog.
Someone told me to replace the capacitor property located before the transformer and the resistance because it has overheated.
Do you know the values of resistance and capacitor that are before the transformer? The condenser is clearly SMD type, I can replace it with a normal capacitor?
What kind of transformer should I ask to electronics store for replace it?
Thanks in advance.
I have the same issue except mine got like this after the first day. I just got it today and the flash won't work anymore. Stays on and even the focus assist beam works. I'm going to get an exchange and if I have a problem on the second one, I will be returning this as a whole. Unfortunately, I ordered a second one that should be coming on Friday.
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
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.
Same problem here... kind of. If I press the 'pilot' for like ten times it fires a single shot then it stops responding.
Do you have any idea about this? I can send it back to China but shipping and custom duties will make it seen a lot expensive than it was intended at first...
Thank you all.
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?
Faulty unit? Anyway, try to screw it tighter and see how.
was the flash bulb just blown?
I have the same problem! Did you find a solution?
how did you do it?
had the same problem with my canon 600ex-rt.
its the shoe mount....there are replacements for it on ebay.
Yongnuo's PC Sync Socket will not fire my second flash that's connected to pc sync.
Are you guys & gals having the same thing?
Equipment is Canon EOS-1D X, Yongnuo YN-565EX, ATG Quantum QFlash (pc cable to Yongnuo's pc sync) with ATG Elite Gold Battery Pack
Got the same problem with 4 Canon 580EX II- won't fire. Canon replaced the trigger circuits & flashtubes.
Maybe that you have set your first flash to be a master to trigger the second flash, thats y when you put the second flash on thecamera it wont work. maybe
I have the same problem - taking it up with the Ebay seller - not happy about this though
Mine does the same thing brand new right out of the box.
Try it in slave mode and see if it works and clean the hot shoe contacts.
Twist the top of the flash. There should be a sticker on it with the month and the year.
Always turn the camera and flash off when removing or adding a flash unit to the camera.
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
Hey, i am a german, my Englisch is not so good, sorry.
The "Yongnuo YN565EX" - is for Nikon Cameras (i-ttl). Not for Canons :)
nonsense!
They have models for both!
what was it
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
Hello i got mine today and i have the same problem!! Did you solve it ???
+Antreas Ioannou me too 😭
did you fix it?
+abdullah omish yeap , don't use alkaline batteries!! Duracell took 5 shots and died. get some good rechargeable batteries.
+Antreas Ioannou I got a new batteries but the light stays green and the flash didn't work at all 😭
+abdullah omish listen am using it on a nikon ... I test it on a d750 and on d3300 and it is fine. I ve heard that a lot of canon users have problems with the 565ex. but try to put it on manual with the mode button and check it off camera . but mate I strongly believe is the batteries...
This sucks. I have the exact same problem. Unwrapped it, took a single picture, and then no more. Same sounds an everything - plus a rather odd smell from the bulb area.
don't complain that item if still in warranty!!!! u can return it
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
I have same problem. It was working OK for about 10 flashes and now just stopped... :/
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.
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.
It's sounds like the flash tube has been broken or is non functional. You can buy a new one on eBay. :)
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
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 !!!
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.
IKEA batteries????
actually youngnuo isn't japanese, it's a company straight out of hong kong CHINA.
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
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...
OOOPS!!!!! i was looking at the wrong side, I found it , built dec, 2011
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.
smarsh599 he has the exact same flash twice, so your point is not valid if the same batteries worked on the other one again and again.
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.
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.
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!
I bought two yongnuo. They both stopped working at the very same time with the same problem of yours. WTF!
OFF THE CAMERA FIRST BEFORE INSTALLING SPEEDLITE!
New flash fault
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
They have canon models. Look it up before giving false "facts".
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 !
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.
+Pablo Guedes Where is the cable, you are talkin about? My 565 works not propably. It does not turn from green to red. Even with new batteries...
The zoom of the head flash works. That cable ajustmant the zoom too. This cable is from the body flash ro head flash.
+Dschingels excuse me, nowadays Im having the same problem with my 565ex, did you find what the problem was?
Hey, how do you putt the cable in the right position again ?
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...
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...
lol the canon flashes are made in china too lol
Same thing happened to me. even the testing button not working. what a crap.
Please don't buy. waste of money.
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
What did you expect from a Chinese flash no QA 2 from 10 not working in all made in china stuff
