This is the only channel that goes more indepth and physically shows you how the components work, i really enjoy your lectures, you simplify things to understand more easily,GREAT VIDEOS, thank you.
I've been trying to figure out why a few of my Eurorack modules don't work, but have a very basic understanding of all the components. You did a great job breaking down the ICs and traces so that I could get my brain wrapped around it. Thanks a lot, and great job.
Thanks bro..i understand your english..now i already repaired my PWM which damage..the VCC capacitor damage hence the ic need to change new one..now my ultrasonic function well..thanks bro
I appreciate for your good explanations kindly make a video to differentiate between a power ic and sound ic and how to track power supply and display on a woofer on a pcb
@electronicsrepairbasics_erb I followed all your instructions but my bios does not have 3.3v on pin no.8. The 3.3v is available on the board but does not get to the bios. I searched everywhere on the internet for the board schematic with no joy at all..lenovo s130-n4000-4g-5304831-2100-890
Thanks a lot, no one has ever explained in such detail i wish i knew you when i was in college. Can you also work with LED, PLASMA, LCD and other flat screen tv?
How about a video on actual voltage testing of ICs and other electronic parts showing readings or limits actually displaced on Multimeter which to expect for defects or good items. Plus a video on power lines of motherboard, how to find the start and end of various powers (19V, 5V, and 3v or 3.3V) when no schematic available. Thank you for your excellent videos very informative for us newbies.
Great video btw! One question. Why is the IC shorted but not the power capacitor? Would love to know.I tested all of them on both sides and their is only one ceramic capacitor that was beeping on one side.
20:18 Question: Why I thought that there would be two causes of this kind of short circuit one is a shorted ic and the other is a short within the capacitor itself, isn't that right ? Please explain this point. Thank you for your great explanations.
Hi there, You will Get exclusive content, unlimited upload of laptop schematics, and my contact number to help in real-time in computer repair if you become a mentorship experience member
Thank you so much for your kind words! I’m really glad to hear that you’re finding the explanation helpful. If you have any more questions or need further assistance, feel free to ask. I’m here to help! ❤️
@@electronicsrepairbasics_erb I have a dosing pump system for swimming pool chemical calibration but currently is not powering up. I tried the fuse but it is ok, what do you think I should do?
I have an Asus transformerbook model T100TA that got water damaged . I checked the motherboard and found a series of ceramic capacitor , around the power management IC , were shorted . The IC is not hot , I tried desoldering the chip to see if the short stopped , but I still have shorted ceramic capacitors . they are many around the IC , I don' want to remove them one by one to check every single of them
It sounds like you're dealing with a persistent short in the power management area. If the IC is not the culprit and the capacitors are still shorted, the short could be elsewhere in the circuit. Instead of removing each capacitor, you can try injecting a low voltage (around 1V) into the shorted power rail and use a thermal camera or an alcohol test to see which component heats up, indicating the source of the short. This method can save time and prevent unnecessary desoldering. Best of luck, and feel free to reach out if you need more tips
@@electronicsrepairbasics_erb by the way , excuse me Sir , I forgot to mention that there is a series of smd inductors too around the IC . they are squared and grey , but their terminals are underneath them (called smd molding inductors) , I can't reach them with my multimeter's probes . I can see some round circles on top of a few of them , these circles are very slightly pushed inward , I would say less than 0.2 mm deep . could the smd squared inductors be the cause of the short ?
Thank you for your detailed observation. Yes, SMD molding inductors can sometimes be involved in causing shorts, especially if there is an internal fault. The slightly pushed-in circles you mentioned might indicate some heat-related stress or mechanical wear, but they alone wouldn't confirm a short. To properly test those inductors, you can try using needle-tip multimeter probes or oscilloscope probes for better contact. If you’re still having trouble, desoldering one leg of the inductor and testing it off the board may help isolate the issue. Let me know if you need further guidance
I think you mistaken the pin 3 Vout as an output on U20 (22:32 - 22:50) and I don't think it is, is it not actually an input signal to tell the IC that an output (buck regulated) is created by Q27 and Q26? If that was the output why is it not a bolt line, but instead a signal line?
@@electronicsrepairbasics_erb Oh okay I see, sorry, I am a very slow learner, you will advance to step twenty while I still try to understand what you explained in step two!!!😂😂😂
I like video, but im a little scared why so simple capasitors are tested with multimeter, in caps could be some voltages, 25v or more... Caps are not friendly, its should be discharged... Is good to use multimeter on caps without discharging?
I'm sorry to tell you guys that I have a BIG MOUTH!!!! I can not keep a secret. So to every one and to all of you passing by, this guy is the BEST TEACHER in town he really wants you to learn all the secrets in Integrated Circuits so invite your friends and former teachers registration is still open. Question can we watch the videos in sequence?
I have an issue with LED diodes (7 of them) on a washing machine pcb. When I turn on the power diodes do not turn on. When I touch som of their SMD driver transistor's middle pin with my finger or with the multimeter's lead, I guess those are collectors, some or all diodes turn on, but do not stay on more than 10 seconds. Does anyone have an idea what could cause it.
I like your channel but if i have to give you a constructive criticism then that would be to improve on your accent. I know english isn't your first language but it can help you in growing your channel.

bunch of information available on your channel its privilage that i am the subscriber of your channel,thanks for video.
Welcome!
Very good! I am a beginner and your video was helpful in understanding the basics especially without a schematic. Great job, keep it up.
Glad it was helpful!
This is really a powerful way of teaching about complicated electronic circuits for understanding and speedy fault diagnosis. ❤

Yes you can discharge it if you want, but note that the capacitor discharges automatically when the power is removed

Could be bad solder joints, you may have to reflow the circuit board using a hot air station.
Wow master,,,
