Big Bro, you don't know how much I love this channel & other is no comparison on RU-vid, i am preparing my notes watching all this.

Thanks... i am not an Electronic tech, but with A/C and Refrigerators now are inverters i need to learn some basics... ❤ from the Philippines 🇵🇭👍👊

Thank you so much.Excellent tutorial. Very clear. Subscribed.

very easy to understand. thank you for this video. you earned a new sub❤️

I like your teaching style, thanks 😊

Thanks for this video you explained everything very well and thoroughly

Nice and Clear Explanation 🙂

Danku voor het videos 👍

Easy to learn that kind of tutorial nice video keep it up

I like how you are Describing 🙏

Well said

very useful! Thanks!

Thanks brother im learning from you and you made me cleared 😊

Good work thenks

Cool video shot, thanks for sharing it, keep it up, like it :)

Thanks king 👑 ❤️❤️

Very useful sir

You showed how to measure the type and if it’s good or bad, however do you also measure meaningful values to figure out a replacement of a broken transistor?

Thanks. :)

thanks sir

Outstanding! Now if I can learn to quickly tell 3-pin SOT Transistor from a LVO regulator or whatever else looks the same LOL. I suspect adjacent components give me clue?

How do you know if its a transistor or mosfet cause they in both of your trasistor and mosfet are see same components CONFUSING SERIUSLY....Would've been better if you started teaching us on how to spot the difference

Do you know a good website or online resource for obsolete transistors from 1980's to present replacements ? Thanks !

Best video

new subscriber !! so you can test transistors in circuit ? you do not need to remove ?

I’m busy with a centurion gate motor course you just need to diagnose the battery, controller, charger, motor then replace those parts

good

Hello sir .. Thanks you soo much .. I'm really interesting with you explaining... How can I test crystal oscillator with multimeter... Secod: what about voltage value on capacitors if I tested when connect board by electric I can get same values on capacitors... Thanks ..Ali ..khartoum

So I’m measuring one smd NPN transistor on board but I’m not getting any reading on dmm? I have connected base with red probe of dmm and emitter, collector with black probe… no reading on dmm shows… is it a bad transistor? Please help

Hi, I downloaded all your videos, they are the only ones I've seen done well, congratulations. I wanted to ask you for help if possible, I have a PCB of a 16V amplified car antenna, I have identified the 3-pin SOT-23 amplification transistor which bears the abbreviation RC5, it should be NPN, following your test video with the tester being tested diodes, the red probe on the base, the black probe on the collector gives me a reading, the red probe on the base, the black probe on the emitter gives me a reading, inversion of the probes and still gives me a reading..........; I tried with the Peak DCA75 which I also have and it gives me correct transistor values; I do not understand...........

Sir can you use Analog tester next to test smd transistor? So that we can see the defference between analog ang digital tester

This assumes you know which lead is which, not easy to do without a schematic.

How can measure darungon transistor.

Hello sir how to test digital transistor

Bro, I wonder how a transistor works when the base is not in the maddle.

Motherboard is not really repaired unless there’s visible component damage. We need to focus on things like testing switches, motors, batteries etc. A parts replacer

One help sir subtitles please sir

Getting annoyed, don't know what i'm doing wrong literally following what you're doing and get a reading on both sides when in diode mode and this isn't a bad motherboard, it fully works. Getting it on every transistor.

Why you have voice changer on

Never understand this shit
