Emphasizing the correct way the capacitor needs to be placed was great. Your video was thorough and easy to follow your work. Thank you for covering this topic. Extremely helpful.
Good job. Flux helps but also when ever you start soldering clean your solder iron tip and then add a little fresh solder to the tip. (This is called wetting the tip). And when you put it away same thing, clean it and wet the tip for storage.
Just cut the old capacitor off the leads and solder the new one to the old leads. That eliminates the risk of messing up the pad and is simpler to do. You could even use a crimp splicer if you don't want to solder (if it will fit)
Thanks for the video
I think the capacitor being compact with the transformer is building heat so if they're separate a little bit would increase its life span
I have the same exact light and the same exact problem. Now I know the solution. Thanks a lot.
I've got a HYTEKGRO 225 led with a 30w led "controller". I call it PSU. Anyway, it's got the same basic components, and my largeer cap seems to show bulging. Really glad to find your video. Also the cap source. Thank you.
Thank you for showing this video. Now I go to fix my light.
Now if only I could FIND someone near me that can repair my LED fixture that just went out. I really hate this disposable society we live in.
Not to mention many places started charging for throwing away so that they can earn more money. I love to do this kind of job but I think I'm living in wrong place. The other day I literally picked a wall clock from the bin and after fixing it's showing me perfect time.
you could always try to repair it yourself, i can’t trust someone other than myself to repair stuff lol
@@tecc9999 I'm a total klutz and have very little patience with myself.
@@nriqueog understandable
Thanks very much for the video, that's amazing works
good job, i have one doing the same, now will take a look
Awesome vid, thanks. I have some string led floods that 2 flashed. I will try to repair them now.
Also, I have an led flood light. Work style with handle. It just stopped turning on all together. The checked the switch and it functions. Checked each led bulb and they all light up. What else do I need to check to see why its not powering on?
Could be a fuse, bad connection or wire, but most probably its the power supply or also called LED driver. Check the input voltage to the driver and output voltage, if its plugged into the wall you should have 110v AC power on the input and depending on the led something between 3v-30v DC on the output. If its battery then the input should be whatever the voltage of the battery is. Also look for damaged capacitors and burn marks in the power supply.
Thank you 😎👍
ive noticed on the regular lamp led bulbs that this has been the same point of failure across 4 brands including GE and Sylvania as well as offshore brands. all but one of a a couple dozen of these were a blown capacitor, seems to be an obvious deliberate point of failure.
Thank you! You are the best!
Great! Thank you for your sharing.
Thank you for kind advice..
My pleasure!
Have you ever repaired a ring video spot light that has the same issue of the spot lights flickering? I’ve seen a number of videos showing where they cut out the spot light drive and replace the lights. Just wondering if the driver can be replaced and where would I get one from. Thanks in advance.
amazing , thanks
i became overjoyed when i saw your -tubba-flux . i have a similar one here myself, although it is a very small metal gravy boat , like a stainless steel one for a very small family of wee folks . this METAL construction enables me to run a heat gun or embossing tool and run the flux into liquid to allow it to resettle nice for easy pickinz and sooth my OCDs . i have been soldering (poorly) since i was 15 . i am 54 now and at this point, proud of my lead slingin skills . i solder often and happliy as long as i have my oateys boat . On a great day in the 90s a boozy plumber name of WILLIE showed me how he used Harveys brand plumbers flux and suggested i do the same when we were drinking beer at his apartment . i was amazed at how well a tiny amount of flux applied served to join two different types of wires together . After the day drinking with willie i never stopped using flux , although harveys is no longer around . i got a kentucky fried chicken bucket size of OATEYS paste flux for around 8 dollars and i am down to only one third left ! i often mention use of flux to people whose builds do not come up , and they ALWAYS say the same thing ... "my soddur alreddy has flux innit" horses - water . i always remove the flux using solvents like iso alcohol , i also clean my stripboards and pcbs with a wire brush and recut all the solder points after applying more , i rub down the dry board with it after using wet sand paper to cut oxidization off and i proudly display gut shots featuring the solder runs in a mirror like high gloss finish , my shit comes up like the morning sun , but boy oh boy have i taken flak from pros techs and experts about "doing it wrong" .suposedly the use of this flux releases mini black holes which consume your private parts .
Hi I have been looking at the drivers of similar lights that are 4 inches in diameter and I have noticed that some have a varistor in the circuit board and some don’t. What could be the purpose and is it better to have a varistor ?
Hi. I have many LEDs like this Flickering. However, I changed 400v Cap but still not solve the problem! what other things make LED Flickering?
@Joachim Shekelberg I replaced the ic Cap no luck. This is the PCB board that I have ibb.co/XJhWhv0
@Joachim Shekelberg I try another Cap to replace cap near IC. it works now
@@Akeshma was the other cap a ceramic one??
Nice video
Excellent
In your video there 2 cap in the driver, how you know which 1 to replace?
Nice job. I have a defiant led 180 security light that is strobing. The converter has printed on it ecla-ccd-120-a-030-0450-00 and it is a sealed unit, can it be replaced? repaired?
The number means nothing. You have to take it apart and replace the electrolyte capacitors BUT you should not tinker with ANY mains connected device unless you absolutely know what you’re doing, how and why.
so what is the point? old cap is bad or something?
Older/used capacitors get weak with passage of time and use and don't give pure dc current. It partly includes ac ripple which causes this flashing.
Thanks for making this vid! I have a lot of these exact fixtures and LED drivers and it seems like the drivers were made to fail. In five years, I've replaced all 30 of mine at least TWICE! Have you found the capacitor to be a long term fix? Do you also have the impression that the fail rate is abnormally high?
EDIT: I just noticed you answered my questions on another comment. Thanks again!
I have updated the link list in the video description with 2 alternative vendors for the capacitors that I used as they seem to be out of stock. I haven't had issues with them for almost 2 years now with the new capacitors
@@JankyShack Thanks so much for the reply! Upon rewatch, I see that you've got the smaller version of what I have installed. I'll probably need to disassemble one of mine to confirm the exact specs on the capacitor.
I'm certain that since 2015, I have replaced at least 60 of these ballasts. They have a lot of different vendors but all look pretty much the same on the outside and are nearly identical on the inside...and they are all junk!
But I'm in too deep! 30 holes with a 9.5" diameter would cost a fortune to do a total replacement with something else that'll fit. PLUS the low clearance that these lights offers allowed me to lay them out right under my trusses (I'm a sucker for symmetry!) so a traditional can and bulb just won't work.
You may have made my day!
Welcome to See-Jen-Pinga (Xi JinPing)'s Chinese product.
U can always use a capacitor with higher voltage but not lower
And be carful with the uF have to be the same and If u didn’t find
U can Use like 6.8uf Replace it with 10uF it will work just fine
You say the uf has to be the same then you immediately says it's ok if they are different. Yeah, that makes sense...
Hi
I noticed that you are not responding to queries
It would be appropriate if you could teach the checking of the different components
Because flickering may be due to other components failing
Yes, you are right. Because I have lots of LED drivers make leds Flickering and changing CAP didn't solve the problem
Sr how abot the slow light how to repair.
Good job
this guy is a danger to everyone with this connection to AC power
Good 👍
I try this with my 70w growlight.
Am how wait is this
I just installed a 16 ft string of stick-on under (kitchen) cabinet lights. In the center of the cabs there's a microwave over the stove, so not wanting to run the lights under the microwave I cut the lights and soldered a length of lamp cord to "bridge" the last 8 ft (up through the cabinets and down). Those last 8 ft of led's are now dimmer and flicker. Obviously, the problem was caused by bridging the strip, but is there a solution to this problem without using a 2nd transformer? BTW, the transformer is rated at 14 watts. Thanks in advance for any help you can give.
Did you try lighting the whole 16' before you cut it? If the second strip is dimmer it seems like a bad connection, but it could also be too small of a power supply. Different strips have different power requirements per foot based on density and size of the leds so I couldn't really tell you without knowing which strip you have.
it could just be the drip from the wire connecting the 2 strips.
Even after changing capacitor i am getting flickering can u please help
It's hard to hear you.
I have the same problem but the capisator is not puffy ,, do you think there are capisators get malfunctiones without getting puffy?
yes. they don't always physically blow.
I love your video but I think you can improve it with few simple things:
1) Learn a little about some basic video editing which is adding pictures and text and cutting videos. Then, with that knowledge, cut the video and insert the picture between.
2) You can put your hand behind the component or circuit but it does nothing. Components are small and a camera needs time to focus on them and your hands need to stay stable during that time. So, in your video, you should have taken a picture of a circuit and a capacitor and anything else that you want us to see better, and then insert that picture between the video where you want it to show (that's why I talked about inserting pictures in the video skill). This way we will see clearly what you are showing.
3) if you need to, use a magnifier and shoot a picture through it so we can see the component clearly
I liked the video and learned a lot, but with these small improvements you can make it a better one.
Cheers!
Are you volunteering to be my editor?
@@JankyShack If it's a paid job, of course. Otherwise no.
@@adorjanc3076 I don't get paid either so that's why I'm not doing all that shit
@@JankyShack Damn! They should pay you for doing it because you are good at it! Anyway, keep on Youtubing
Hi is your fix still working without the flickering issue again?
Yes, the light works great after I replaced the capacitor. I have 10 of these lights and over time I have replaced all of the cheap capacitors with good quality ones and have no more issues.
Janky Shack Same here I have turn off these recessed lights in my garage and all of them are starting to flicker
Will this work for a Toyota?
what basic course can I take to learn how to solder small electric parts? Do you know?
Just buy a cheap soldering iron and watch some youtube videos amzn.to/3toGN0g
Hey community - I have a Gladle LED floor lamp and out of the box the led bulbs are not turning on. There is power reaching at least the power button since it does light up once plugged in but when you push the power button, the lamp doesn't turn on. I'm not sure if it's the power button that's not working or the bulb itself that might be malfunctioning - any thoughts?
I'd start with checking the connection points, from the youtube video i just watched on that light there is a power connection from the pole to the light inside of a screw connection. make sure that isn't pushed into the pole too far or damaged
@@JankyShack I just loosened the screw to free up the cord but it's still not turning on. Any other ideas? It doesn't seem like there is any other easy way to open up the bulb area.
@@omarchaudhry195 impossible to say without a meter
Should the new one have the same number of capacitance and voltage?
Yes
Buy one with a high temperature rating from a quality manufacture.
Janky Shack Many thanks!
Hard working
Wow
I replaced the capacitor on a small led grow light. As soon as I plugged it in. It exploded and caught fire. Any idea why?
You reversed the - and +
6:00 NO!
Installed the same led in my living room, and after 4 months of working fine now 2 of them stay on after they are turned off. What can I do to fix that???
sounds like you either have a bad switch or something else on that circuit with the same neutral is pulling a lot of power and somehow back feeding those lights.
Puffed up = Bulgy
😄
I have flickering with brand new LED bulbs in my door inside entry ceiling light, but no flickering with traditional filament bulbs. It's frustrating.
Do you have that light on a dimmer switch?
@@JankyShack No, it's on a simple ON/OFF switch. That was the first thing I checked.
That is a Mu F, Mu being the Greek symbol we use for micro…
Dear voice is very low.cant hear what you are saying... This could be very useful video but voice issue ruined it.
turn the volume up FFS
Veriy supra boss
Volume of sound is too low, can not really hear you.
Yeah my light is completely different lol no clue what to do
When a LED light bulb is flickering does that mean the switch is leaking current?
No, if the switch is on then the circuit is fully connected. The reason they flicker is because they use a buck converter to lower the voltage. Its a modern way to lower voltage without a transformer or plain resistors. Part of the buck converter is the capacitor and when they go bad the light flickers.
@@JankyShack is it buck converter or flyback converter? I have ic controller HT2538 and OB2538
video problematic by low sound
nah, Just throw away the circuit and put a 1uF ceramic cap in series with the led
So complicated, Lots of equipment and soldering, they have classes to learn this stuff. I’d be afraid to start pulling out electrical wires in my house. Nice, but too hard for me.
Your voice also flickers and difficult to listen. :(
It will still be flickering, thats useless
I've done this to 6 of them and it fixed all of them.
