5 years ago I used this video as inspiration to replace the caps on the power board inside my TV. It still works to this day. 10 bucks in replacement caps.
+phuturephunk Yay! Glad I could help.
This is the best comment to any post ever. I am grateful that you shared this.
@@powerhour4602 okay, take it down a notch.... lol
Now , five years later it's still useful ♥️
im about to do the same for TV i found next to the dumpster of my apartement. bulging capacitors. so ill replace them and hopefully it will work.
You were so ahead of your time in the TH-cam educational sphere. Kudos
Indeed, that was 2008... Today, with 50Hz rectifiers replaced with SMPS's almost everywhere, we also need to care about the ripple currents at 100 kHz plus, - but the basics like C and Vmax still stand.
12 years later. I for the first time I'm my life successfully worked on a PCB and swaped a 8.4uF 400v cap with a scavenged 10uF 400 v cap on my led room 30W light. Thanks for the heads-up about the polarity or I would have surely messed it up. 12 yeas and still helping people to this day. To the point shot and crisp information. Thanks a lot.
This video is a life saver man, thank you for giving a capacitor replacement tutorial that isnt an hour and a half of rambling, short and to the point, I learned more in this two and a half minutes than most videos. Broke out the soldering iron and fixed a Sega Genesis.
A thing I would add to the end of the video: When you face a high voltage capacitor, you will get shocked if you touch positive and negative pins. In order to avoid electric shock, just take a screwdriver and make short circuit between positive and negative pins before removing the capacitor. Just with insulated gloves, lift up the board and make short circuit ( put screwdriver between pins in order to short circuit the capacitor, so it will be discharged and you will not get eletric shock ). You will be able to handle it with no fear. btw nice tutorial! Once I learnt about capacitors, I had in mind this and you prove it to me that it works like a charm!
I kept looking for a video that would explain the voltage rating. Yours was the only one I found that explained the voltage rating of a capacitor. The video is more than 14 years old but still so informative. Old is gold. 🙂
I can't really imagine watching a video that's uploaded 14 years ago and that impressively helpful
That's the way you do a tutorial, good clear audio and video to the point with explosions. Great!
That was a perfect tutorial. Short and to the point and informative. Why can't every tutorial be like this.
@ravengious V=IR meaning that for a fixed resistance (such as your body) more volts means more amps, meaning more danger. And yeah it doesn't take much current to kill you. 50 volts is enough to cause pain. Discharging a 100V cap through your skin will leave a nice burn mark. Anyone who tells you otherwise is a twit who is confusing static electricity charges (high voltage but low stored energy) with low impedance voltage sources. This includes many high school physics teachers.
yay i learned how to explode a capacitor!
Thankfully, these days we pre-score the lid so it goes off less violently. Back in the day, they were mini pipe bombs.
You must be muslim.
No one has ever explained this so freaking easily.....Awsome. Subbed.
I replaced 5 bad capacitors on my Xbox today. I bought it new way back in the early 2000's, and when it stopped powering on a couple years ago, l noticed some bulging caps. I swapped in some new ones today and it powers on.
That's exactly why I am watching this video to replace caps on my Xbox hahah
I may be wrong but doesnt the original Xbox if thats what it is on have a common bulging capacitor problem?
Glad I found this before I tried replacing my capacitors. Thanks man.
Your tutorials are EXCELLENT! I wish I had a teacher like when I was a youth!
Love the style all of this video, brilliant. Also reminded of why it's fine to replace a blown cap with one with a higher voltage rating. Thanks very much.
Looks like I finally found the right keywords to search! This video was awesome and It's not some boring Indian guy that can barely speak English with wires plugged directly into the outlets behind him like 90% of my other searches.
Accurate user name is accurate. (I feel you though lol)
a very clear explanation
This is awesome. Using this advice and others, I picked an LG 42" LCD from the dump (paid £20 for it), replaced four capacitors in the power supply, and I have a working HDTV for about £25! I used Rubycon YXF to ensure the repair would last... has done so for about 2 months.
Finally a TH-cam video with excellent audio - thank you!! Also thanks for your clear explanations. :)
I just replaced a blown 400uf 300v capacitor without having any idea about it aside from the given data here. After watching videos about capacitor, I'm just glad I didn't had an accident while I was poking the damaged one with a screwdriver.
once i was working with a power supply and i was fairly new to electronics, there was a 240v capacitor that was charged and i placed my hand under the circuit board where all the solder joints were, and after that i was shaking fir a good ten muinits
F E L E P you should have used fake hands to change that capacitor like they use on Fallon. Just look up on TH-cam .......Fake Hands Jimmy Fallon. Your welcome
hahahaha, I have
but that was before I knew he existed
excellent video, all information needed in a short amount of time. 10/10
One of the best, most concise vids I've ever seen on YT. Excellent job! I learned a lot! TY
it's very useful
@@neetirg why
Very well done. One note of importance-it should be made known in your final warning that the capacitor might have that 200 volt charge even if the equipment has been shut off or unplugged. Harry
Well explained sir. I was moving in TH-cam about capacitor. You've cleared my doubt absolutely 100%. Thank you so much.
thanks .. your videos are awesome. I learned alot from it.
You didn't just tell us how to make an amplifier you also explained how it works,why the components were putted together... You taught us how to build one ourselves.. Thats what I love about your videos.. thanks alot..
Thanks for this video! Well explained, good editing! Funny too!
This is a pretty smooth video. Fark, Engineering degree in 2 min
SIMPLY THE BEST, without any other fancy pancy words. Great tutorial!
I love this video. It's incredibly helpful yet fun to watch.
informative and funny as hell
Funny and informative presentation! Just one question: how do you know if a capacitor is charged?
Enjoyed the short, informative video. I've been replacing caps in some HP monitors for a couple of years and I've learned a little something. Thanks.
Thanks for the very direct and precise tutorial. This just answered all my questions altogether. Thumbs up!!
You could mention how to discharge big caps
The best way is to use a resistor to short the leads of the cap.
i always just use a screwdriver, works fine, i dont give a shit about damaging the capacitor since it's probably broken if i'm replacing it
can you do it with any resistor?
What should be the value of the resistor?
Just use screw driver and short it and done
wow looking back now i think i thew away a plasma tv that probably only had a blown capacitor.
Just started to research on how to replace capacitors and this is the first video I clicked on. Great video and explanation in layman's terms. Thanks for the post.
Thank you very much for your work and your time - priceless!
Cat? Subscribed!
when I haven't done it for a while I always forget which one I can go up on, the V or the mF. so thank you for keeping this up here!
What about temp? Mine says: 105°C8 What does this mean?
I'm sure it's max heat before malfunction
Best Capacitor Class Ever!!! Thx man you solved all my doubts about it!!
Simple and fantastic, all videos should be like this. Thanks!
The last secs killed me lmfao
HA HA HA! The suicide visual did it for me!
Direct, concise and effective explanation of what a capacitor for the ingnoramuses llike me to take the plunge and try and change one of these suckers from a faulty LED TV set. Many thanks!
Master teacher.I like how simple you teach.Good job.
@0:58
i once touched a 400v cap which was charged xD it hurts like hell
+TheIdiotPlays Awwwww, dont want to happen....so.....for everyone.....how do you safely discharge a capacitor? Noob need answer.
Stick an insulated screwdriver between its pins.
what is the name tools for replace the Electrolytic Capacitor.?
Thank you for such a simple and easy explanation of capacitors.
Your sense of humor is perfect. Great vid.
Thanks for going by a class 101 approach, excellent and to the point. This is how to get subscribers.
Gotta love when the first video answers the question you don’t know how to word, thank you for the voltage rating info section!!
Dude, this is so awesome! This is a great way for people to learn about this stuff! (I didn't know what else to say) I've just learnt a little more today! I have a huge collection of old animatronic battery operated stuffed animals that run on this type of capacity. Even though I'm a young teen, I've learnt a little bit of this already myself before I saw this video.
Short, informative and engaging. Thank you so much.
I'm learning this stuff as I go along on youtube and this video is the best that I have found.
wonderful, this is exactly the tool I was looking for for changing faulty capacitor on a Dell mother boardThank you very very much
Wow, what a SUPER GREAT video. Thanks for the short and sweet explanation of Capacitors.
Great tutorials you make. Just what a newbie as I am needs. Thanks very much.
This video just saved me lots of time and probably some money too. Thanks!
hi Dude, thanks for the tutorials you explained well....
Thank you very much for taking the time to post this video. My vintage Revox A77 Needs some "TLC" Your vid is a great help. Thank you,
Awesome video. Clear and concise.
LOL awesome video! thanks for posting. im about to venture into stereo repair and this video is a great intro for those of us who know nothing about replacing caps,soldering, etc etc etc thanks again! :)
Perfect. This is exactly what I was looking for!
Exactly the information I needed in exactly the amount of time I have. subscribed!
Thank you so much for simply explaining something simple and not mixing it with the usual electronics Voodo mumbojumbo.
Great video, this is exactly what I was taught in electronics class.
i just gotta say that everything you say and the way you explained?
amazing thanks
This video is the highlight of my morning so far
Short concise ,informative excellent................
Excellent video. Humorous and educational!
This was the best video ever. Now I can replace my power board capacitors with no problems. Thank you
Thanks for the advice, i'm just trying to replace some caps in my old DVD recorder, so this vid has come in very handy.
Concise and to the point. Thank you!
Thank you for this video. Great sense of humour also! Cheers.
Wow! It's been forever since I've been on your channel or seen one of your videos! This video was a huge help in figuring out how to order a new capacitor for a dead computer monitor. All I can hope for now is that this swollen capacitor is the reason the monitor no longer powers on and that replacing it will fix it up good as new.
Very well explained! thanks compadre!
Fast clean, simply a good tutorial
Very useful and clear explanation! Thank you!
I just had to subscribe just because of the comic relief visuals and voice humour. It is great.
Fantastic I have been searching for this exact thing. Thanks Afrotechmods!!!
Solid! Straight to the point. Thank you.
tq.. really appreciate all your video because it suit to people who know little electricity or electronic. i still can follow all your video. i am going to watch them all..
You are really a big help for understand this electrical stuff. Thanks
They way you explain is very use full thanks.
Thank you. You are a very good teacher. God bless you !
Thanks for making electronics fun!
your so good! giving a clear and vivid elaboration.... wish ur my teacher!!!!
I love how capacitors explode.BTW,these tutorials are the best.
Great video.. Witty, informative and concise
ALL I CAN SAY IS, YOU ARE A WORLD CLASS !!!
Best explanation. thank you 🙏
Just brilliant quick and simple.
excellent job ....short ,sweet, informative.
It was really fun learning about the capacitor. Thanks :)
Very clear explanation. Your voice sounds crisp. Keep up the good work! Thank you!!
@l28power Agreed. Whenever possible, purchase capacitors with low ESR.
excellent video a 10 out of 10 perfect narration precise concise and to the point
