Troubleshhoting logic board components

Thank you for the good info.

You have explained capacitors in a way that a person with very basic electrical knowledge (such as myself) can understand. I read your information from beginning to end. Thank you for sharing.

Thanks for the precise and easy to Understand information on Capacitors. Well done!

@joakimk that is a great idea. I will expand on this is the near future. Currently working on resistors, diodes and fuses.

Great reading and learning.

Thank you a million times AND Massively Big Hugs to you for saving me hundreds of dollars ... I have an Amana washer and one of the two capacitors was giving unusual readings as indicated in this "IFIXIT" manual, so I decided to re-solder the one that gave a strange reading and viola, it cured the problem immediately ... the thing that alerted me to a soldering issue was the dull colour of the solder on that one capacitor, whereas the other one had bright and shiny solder ... thank you a million times for all that you do to enlighten and educate the public and save us a few dollars ... Blessings be upon you and your kind heart ... 8)

Thank you great explanation

I must say this was the first web lecture I enjoyed learning ...

Nice keep it up

Very useful and simple explanation to understand and to save lot of money. Thank you

Thanks for the Information, Very useful and straight to the point, keep up the good work.

This is soo gooooooood!! Thank you! It`s so hard to find good learning material on this subject.

bravo sir i understand you make explan simple

Thanks for that explanation

Very helpful, thanks!

Very well explained info

thanks

Thanks for the simple explanation!

Thanks, for the very informative article!

This is a very explanatory write up... Very elementary and useful for all level of electronic understanding…thanks alot for this?.

Hello!

Thanks for your detail explanation. I also have some questions which i have CBB22 in my hand in this company write 355j 400v.

I want to check is this mentioned volts are DC or AC. and how I measure the volts??

You are the tutor I need because You made it possible for a hard head like myself understand, thank you.

Here is a very informative article about Electrical Bonding.. please follow it..

Why cannot I measure capacitors in circuit using a multimeter with a capacitor measurement mode? I only need to check whether the capacitor is dead or not, no need for the exact capacitance value.

Hi ihave a tv capacitor 450 volts 100uf.when tested it reads198uf would this be faulty? Would be greatfull if you could get back.

1000uf 50v electrolytic capacitor testing with esr reads 1940uf. This is a bad cap right? Thank you!

Thank you, i have learnt something from your wiki.

Thanks for your comprehensive article. It helped a great deal - my treadmill was moving erratically and after reading your article discovered that a large electrolytic capacitor was positively bulging at the top!

Great explanation. I have learned electronics only for Physics in Advanced Level education (2 years in school just before entry to the university in Sri Lanka). But I clearly understood everything you have written and that is very much useful. Thank you !

Thanks that's great

thanks, easy to understand

Very insightful and clear explanation, thank you very much.

Great general summary but I strongly disagree with the advice quoted below about using ‘higher capacitance values’. Replacement capacitors should ALWAYS be of the same nominal capacitance value as the original. Yes, there are cases where a circuit needs only a minimum capacitance to operate, so using a higher value would be ok. But there are many cases where a specific capacitance value is required for the circuit to operate correctly and safely. Don’t risk it. Use the same value, type (electrolytic, polar vs non-polar, etc.), and package size as the original.

It is acceptable to use a higher voltage rating or smaller tolerance value than the original if necessary. For SMD caps, using a higher class of dielectric can be acceptable (i.e., if original cap was ‘X7R’, a ‘C0G’ replacement should be acceptable).

When replacing a capacitor, it is of utmost importance to replace it with a capacitor of the same, or higher value. Never subsidize with a capacitor of lesser value.

Thank u very much

Awesome!

Great old dry stuff that never gets old.

And the pictures are the cherry on the circuit.

Your great work is much appreciated my friend
