Wow, this was a really good video, and I'm sure you've helped a LOT of people. To anyone else who just watched this, there are other ways a capacitor can go bad that won't bulge the top. Often this can be detected with an inexpensive " ESR meter" Regardless, this vid is a GREAT start!

This is a really fantastic explanation. You've done a great job here. This is awesome. I'm just getting started on this. I have 6 capacitors on my board that are bulging and have heard brown rust on. Thanks again, this is great video.

Thanks for the video. Question - is there a temperature to set the solder gun at for this type of work? Hope to do a vintage turntable re-cap and wish to be careful.

Thank you super great video🎉❗️

can I replace a high-voltage ceramic capacitor 100pk/1kv that is not original for a TV ?

Thanks for the video, explains so much about the run of bad caps during this era; monitors, appliances and auto... personally, I like using a solder sucker. my next re-cap of all places is the FICM - fuel injector control module in my duramax. There is a cottage industry charging upto 2k to "reman" these out-of-production "FICMs" 5 caps ($20). The caps on this Bosch board blow hard and down and invariably take out the pcb. Shame on Bosch for not mounting the caps horizontally, as on the board in your vid, so when they blow the cap vents without destroying the board.

I would highly recommend discharging them before any desoldering, electrical charge maybe present (internally) even after a long time of no usage, to do this simply touch both leads with an insulated pair of needle nose pliers to discharge any remaining current, then you can desolder the pads and remove them

I want to experiment with 12v ride on car circuit board. What soldering kit should I start with

I get paranoid. So I might replace one at a time. What do you use for cleaning the tip

no desoldering tool?

I am mechanic but I am looking for a job

exactly what I needed to get the confidence to reinstall windows using dual boot to keep my old install as a temporary backup.

what do you recommend I use to hold an xbox 360 mother board? I am getting ready to do this on blown capacitors on a xbox 360 motherboard and I am looking for the right thing to hold it, like you have in this video. Thanks.

Rocking the capacitor back and forth must be done carefully without putting any downward pressure on the lead which has been partially extracted. Otherwise, the solder pad can detach from the board. I prefer to use a solder sucker to remove the solder from the joint before trying to lift the capacitor as it will often fall out by itself if this is done. If not, just heating the joint will often free the lead. Applying flux to the joint makes the process go much more smoothly and prevents overheating the board if solder does not melt as soon as the iron is applied. I agree that only suspect capacitors should be replaced. After visual inspection, the ESR (equivalent series resistance) of each electrolytic capacitor should be checked as capacitors often fail when they look normal but the electrolyte has dried out. I have an old HP distortion analyzer from the late 1960's that has not needed a single electrolytic capacitor replaced. Back then, electrolytics were made to last, often with epoxy seals instead of rubber.

Repairing power supply, analogue boards are O.K. If U need to replace capacitors of a PC monther board, the holes are too small , function as designed to throw away if caps are bad.

Great video! I would like to add that bad capacitors began to flood the market in the 90’s. My Panasonic Omnivideo VHS camcorder is a prime example of this.

Nice video. I was told Capacitors work in a series, so even good ones must be replaced, is this true?

Thank you very much, I really appreciate this video. 👍👍👍

Excellent work.

💡If you get a black screen after choosing the operating system, reimage from within Windows 10. Do not click "Fix Windows Boot Problems." You still will be on C:\ and have a second OS partition with another drive letter. Open the Command Prompt or Powershell with Administrator privileges. Type bcdboot G:\Windows replacing "G" with whatever drive letter Windows has assigned your new partition. You should now get the Windows boot manager when you startup and be able to boot into both Windows.

@Luca_TbS said: "not working, black screen after choosing operating system" 💡Reimage from within Windows 10. Do not click "Fix Windows Boot Problems." You still will be on C:\ and have a second OS partition with another drive letter. You can see this from Windows Explorer or from Macrium from within Windows 10. At this point, if you reboot, nothing should be changed. You will boot up to your original Windows 10 as you always did, back to the place you were after you created your new second image. Test this out. If this is the case, do the following: Note the new drive letter of the new partition image, and open the Command Prompt or Powershell with Administrator privileges. Type bcdboot G:\Windows replacing "G" with whatever drive letter Windows has assigned your new partition. I also added the commands, /addlast, and /d, when I did it, but I don't think they matter. They only determine the order in the bootmanager. So I typed: bcdboot G:\Windows /addlast /d That's it. Reboot, and you see a blue screen bootmanager window, which allows you to choose either version of Windows. Everything should boot up on either. Here's the catch, and probably why it wasn't working for you. Windows apparently can only run from a drive marked "C:\" because everything in the registry points to C:\. So when you load up the new second partition image, it will change its drive letter to C:\. It will furthermore, assign your previous C:\ drive a new drive letter. "D:\" perhaps. When you boot up the original partition image, D:\ will be C:\ again, and C:\ will be G:\ again. When I imaged from a Macrium PE disk, my new partition image was suddenly marked C:\, and the original C:\ was suddenly marked D:\ immediately after my reimage ran (as it does in this case on the 2nd partition image). This made things problematic, possibly for Macrium "Fix Windows Boot Problems," and for myself, as I tried to fix the BCD. As bcdboot writes the data to the bootmanager from the drive you specify. Read the following to clarify what I've said, about the BCDBoot Command: learn.microsoft.com/en-us/windows-hardware/manufacture/desktop/bcdboot-command-line-options-techref-di?view=windows-11 learn.microsoft.com/en-us/windows-hardware/manufacture/desktop/repair-the-boot-menu-on-a-dual-boot-pc?view=windows-11 Anyway, to get more involved, you may run the following command beforehand, to view your BCD, from the Command Prompt or Powershell: bcdedit this should initially show only your one original partition entry, but after you've typed bcdboot G:\Windows , it should show two. See: learn.microsoft.com/en-us/windows-hardware/manufacture/desktop/bcdedit-command-line-options?view=windows-11 You can see your partitions beforehand from the Command Prompt or Powershell, by typing: DISKPART LIST DISK SELECT DISK # (designate "0" or designate correct disk "#") LIST VOLUME LIST PARTITION EXIT See: learn.microsoft.com/en-us/windows-server/administration/windows-commands/diskpart (or see your partitions in Macrium possibly by clicking "Refresh") If you run bcdedit and DISKPART after booting up each new image, you can see they will return different drive letters. Anyway to get more involved, if you care for the reasons why we got the black screen with the cursor, it may get kind of complicated, but may concern somewhat what he's talking about from 20:21-21:08. And because everything in the Registry is pointing to C:\. It is discussed further at: www.aomeitech.com/forum/discussion/2905/backup-c-partition-then-restore-to-f-partition-causes- screen-flicker-when-booting-to-f and here: www.goodells.net/multiboot/partsigs.shtml Note: All of my advice above, is for GPT EFI (ESP) drives [which are more generally PCIe, NVME]. Not sure about MBR Bios drives [which are more generally SSD, or HDD].

what do you clean the tip with just run it across a wet sponge?

I've only ever soldered a few speaker wires together in the past, and never done any PCB work before. My 60" TV wouldn't turn on and I narrowed it down to a bad capacitor on the board. This video gave me the confidence to give the repair a try, and for just a $5 capacitor and an hour of my time the TV is now back up and running when a week ago I thought I might have to junk it. Thank you!!

Awsome help thanku sir😊😊

what is a cold solder joint? thanks

Nice video, keep it up, thank you for sharing it :)

Thank you! I was initially completely baffled about how to remove capacitors and for some reason assumed that I was supposed to use solder wick but of course, through-hole components are different. You just saved me money and a lot of time because I would have resorted to buying/waiting for a replacement logic board from China for my Dell E2310Hc. Two cheap replacement capacitors later (as per C. David Graves's repair video) and my monitor is as good as new again. I even managed to do it without a clamp/stand, by just "pinching" the cap with my fingers and the board resting on my mat - switching pinching/soldering iron hands also helped with the angles. :)

Awesome and informative video.

Great video! Useful info for something I am about to do!

That's a nice looking vise and you do a great job at explaining nuances of this work

Harder than it looks. Especially if the pins have been bent over.

Made that look easy. Great video

Nice video , did you shoot that with a drone ?

this is waaay harder than it looks. Trying to replace 5 caps on my original 2001 Xbox but the solder just wont melt. Ended up pulling the caps with pliers cold then drilling out the holes. I got caps of same uf and v on ebay. Yageo is the brand. hope they are ok, they are a bit smaller than originals. Now im having trouble getting the solder to stick the legs to the board. Will have to try tinning the legs maybe. Have i killed my Xbox? I dont know what to do. If I buy another one it could have same issue.

Thank you very much for great info

Fantastic video! The animations are superb and help understand a somewhat confusing and complicated topic!

Superb!

I fixed the same monitor about a year ago had one cap that had bulged in the same area. Replaced the cap and now the kids are using this monitor with their pc

Hey Dan. Great video. Where can we get a vise like that? What is the brand name? Thank you.

Thank you so much. I was able to repair my mother board. You procedure for replacing caps is perfect!

Thanks from kochi

Helpful thanks

A lot of thin soldier connections seen on the video

Thank you Dan. This video was just what I needed. I followed your instructions and everything worked out great.

The other element to replacement capacitors is ### Tolerance ### to minimize "Capacitance Drift" particularly with computers and highly accurate electronics such as Class AA & A Amplifiers where it can impact the quality of the audio (bandwidth - high/low-pass filtering, frequency response, Capacitance drift The capacitance of electrolytic capacitors drifts from the nominal value as time passes, and they have large tolerances, typically 20%. This means an aluminum electrolytic capacitor with a nominal capacitance of 47µF is expected to have a measured value of anywhere between 37.6µF and 56.4µF. (This is to reduce manufacturing cost.) Tantalum electrolytic capacitors can be made with tighter tolerances, but their maximum operating voltage is lower so they cannot be always used as a direct replacement. The voltage may also be expressed as an alpha character. Letter - Voltage e 2.5 G 4 J 6.3 A 10 C 16 D 20 E 25 V 35 H 50 Other issues. 1. Capacitors are like a fine wine - don't end up with vinegar. Capacitors do age and aged capacitors' performance degrades. 2. Authentic Supply Channel - don't end up with someone else's rejects. 3. Check the polarity of the currently installed capacitor before removing it and go by that as polarity markings on boards have been known to be erroneous. 4. For reliability's sake and saving of time, it is best to replace the capacitors of a whole "module" at a time. As per point 1 - the degradation of capacitors (up the line) can impact capacitors (and other components) further down the line. Not everything fails at once yet may be on it's way to failing. Components in the process of failing can cause other components reliant on them to fail first.

Hero level video! Clear, concise and to the point. So much info crammed in this video. Perfection!

Do I have to discharge the capacitor first? Just wondering. Going to try to replace two on a Hisense television

I need a cap job. My hands are too shaky to do it. I can send you the PCB (4 box caps and 2 axial caps) and you don't have to disassemble or assemble anything. Do you have a website for your place of business? thanks

..thank you..
