Never wouldve expected someone who plays a banjo and goes by the title "Peepaw" would be one of the best teachers of not only electronics but also shares some great wisdom about life from time to time as well. Thanks peepaw, I really appreciate your time and insight!
I have watched a lot of videos with fancy equipment but haven't had it explained so easily. I have some computers to fix and this really helps without me having to spend any money on tech I don't need.
Thanks for this tips on finding the shorted circuit IC. I learned and found the damaged IC of the dishwasher and replaced it with success. This will be very useful for my continuing exploration of the electronic world. I am not trained in this field but just learn the knowledge through the TH-cam videos such as yours. Thanks again.
Thank you for your down to earth, easily understandable videos. They're helping me immensely in my electronic repair hobby. Hope all is well with you and yours during this chaotic time!
Hello Sir, I am always happy to see other folks that are interested in electronics. That is great that You and your Grandson are learning about this craft. It's a life long learning process. I thank you very much for stopping by. And I hope you are having a good day.
As a basic ground floor hobbyist I'm forever releasing the magic smoke! LM386's being the usual suspects so knowing how to confirm suspected disaster is really useful..love the hobby, love the mistakes b/c I learn from them more than anything else. Big respect to all the guys who put these videos out, thank you Peepaw
Thank you so much for making this video. It is exactly what i am looking for to test the ic in my alarm clock. All of the sudden, the buzz dropped so low, it doesnt wake me up anymore. Peepaw, you are the best😁😁😁😁😁😁😁
My granddad gave me the HIOKI DT4282 multimeter. And uncle gave me the CEM DT-9889 multimeter. I believed yours (0.00) and mine are all good. But I aimed more using the CEM DT-9889 to troubleshoot faster by using the ATG thermal imaging camera. My little daughter loves playing the CEM.
Hey there, I’m terribly inexperienced with electronics (I’m 17) but I’m trying to learn, so hopefully you’ll see this and have some advice. I tried this with a random circuit board I had with a few ICs. I tried to replicate what you did as best as possible. I put my red probe on the chassis (which was bonded to the IC ground) and put the black probe on all the pins. My voltage drop readings were bizarre... Most of the readings were around .7, but some were as low as .4 volts and some were as high as 1.666 volts... What?! In fact, numerous pins just read infinity (1. ) on the meter, which I didn’t understand. One of the ICs on the radio board tested shorted on an entire side of the IC. (The radio was unable to tune anything, I wonder if that IC was the cause?)
Thx for the lesson i'm trying to fix a Roland TR-606 drum machine and learning about the TC4011B Quad 2 input NAND Gate cause i know that has been causing me problems. Question wht type of multimeter should i buy cause i been learning to repair other small Drum Machines learning more about Ohm and Diodes.
Nyor is right, Peepaw says "put the red lead on ground [pin 10] then go around the other pins with the black lead. I'm a noob too, so I could be wrong but it seems to me like, one should put the black lead on the ground and go around testing the other pins, with the red lead. Correct me if I'm wrong - please give an explanation
heres a really late reply haha, from the datasheet, the diode's positive pin is at the ground pin of the IC. If you test the diode with the multimeter, you must connect the positive side of the multimeter to the positive pin of the diode, in this case, it is the ground pin.
Hay Peepaw since you are so good at this I havd a question. I need to find out how to figure out if a eprom or a small memory chip is bad. Can you help with this please? Currently looking at B&K 575. But too expensive. Is there any cheaper way but I not looking to get some cheap tester. I need reliability. I understand the concept of when in doubt, replace. But the chip has been out of production and discontinued. my only source is also not reliable' eBay or Chinese made.
my multimeter on some pins shows voltage drop around 0.1V while others(good ones i think) are around 0.6V or 0.4V... is this IC shorted or i'm just getting wrong reading?
Only one. I wish I could salvage an integrated circuit with just one output or input shorted. But the circuit boards that they are attached to want a completely functional integrated circuit. Thank you so very much for watching one of my videos. I hope that you and your family are doing well.
I have a question. Would someone be able to use this same test on a TL071 IC that doesn't have a specified ground pin? If not, would you have any knowledge of a test to use to check if the TL071 (or others without a gnd pin) is faulty? Thanks for the lesson thus far!
That is a very good question. Please give me a day or two, and I will perform the experiment. Then I will post a video for us to watch of the results. Thank you very much for watching my video. I hope that you have a good day:)
Hello Mr. Warfield. I hope you are having a good day. Yes you can use this method of hunting for short circuits while the IC is on the board. Here is one of my videos doing just that very bit of work. Click on the link and enjoy. th-cam.com/video/Dx1emYj-rcY/w-d-xo.html
Hi Peepaw MacDonald, thanks for this video it is very useful. I have a question and that is. I have got a gamepad which doesn't work properly anymore. Actually when I plug it into power through USB it gives a sign of power but the pc said that the device isn't recognized and it won't work. So that, I have started the PCB troubleshooting and following your instructions I tested the IC which is a very small 32 pins one and with my multimeter I found out five points where I assume is a short, respectively D+ and four digital I/O. With short I mean that the multimeter doesn't show me anything on display. Moreover the IC shows a small brownie spot on the surface pretty close where the short were found. Now I would like to ask you a confirmation of what I told you and if you think I am on the right way or not? Thank you very much in advance!
Maybe you can assist on this.. Do you know how to get, make or mod a high gain/high reception antenna on 2.4GHz camera's transmitter? The TTL transmitter or TTL receiver operated on 2.4GHz. When I opened the cover up I sees a Zig Zag Circuit & I think that's the antenna. I do not see the Ground for that antenna. While many 2.4GHz Antennas have center (hot) & ground (negative). Where would I solder the ground from the antenna to? And how long do I make the antenna for maximum receptions? I would love the WiFi to be up to 500 meters.
How do you locate a short on a circuit when let's say a 3-volt line that is feeding to the different parts of the circuit is shorted? Most circuits I encounter doesn't allow me to just break the circuit or isolate the 3-volt line.
Hello, I hope you are having a good day. I hate 3Vdc circuits. I worked on one that I had measured 1.5ohms from Vcc to Gnd with my Fluke DMM. Now ask me how you find a short when it normally measures that low. I had another board that was booting up good. And it the good board measured 1.5ohms from Vcc to Gnd. That is insane.
I powered up the non booting board. And felt around with my finger and found an TTL IC that was extremely hot as compared to the other IC's. It was so hot that I could not keep my finger on it longer than a half second.
Another thing that may help. Electrolytic Capacitors and Tantalum Capacitors fail. And when they do, they can cause short circuits. I hope this helps you troubleshoot your circuit.
You know what would be neat. If I could inject one electron into the faulty circuit. And it would report back to me the exact location of the short circuit. Oh well... maybe someday... Until that lucky day, it is you and me to find the fault.
Hi. Im wondering if you could help me. I have a tms3450nl IC. I also have the data sheet. I want to test it but nowhere on the data sheet do i see a ground pin. Can you help? The volume went low on this (alarm clock).
Yes absolutely. You can perform this test on the board. I do this test all the time on the circuit board. Let me know if you are successful. Thank you for watching one of my videos :)
question: bought 2 new Philips UAA 1250 IC chips. It will not test as you have shown and I can not find any data sheet on this chip. It is used in a dome light assemble for a car 1992. Any ideas where I can get this data sheet and why will not test as you describe ?
I also tried and failed to find a datasheet, so that I could answer your question. But you can find ground of the IC if you can find perhaps an electrolytic capacitor that filters the 12Vdc onto the board. I am assuming 12Vdc because you are speaking of a car. Usually the ground side of the filter electrolytic capacitor will be ground of IC's on the board.
By the way, why do you think the UAA1250 is bad. Is there a hole in the middle of the IC? Do the dome lamps no longer work. I am curious for other peoples troubleshooting stories.
One more thing. It appears that this is a custom IC manufactured by Philips for Mercedes-Benz. That would explain the lack of datasheet. Thank you very much for stopping by and watching one of my videos. I hope you and your family are having a great day :)
@@PeepawMcDonald Yes on both accounts.. there appears to be a hole where or close by the mfg hole. Also, I believe this chip controls the lights when the doors are opened or unlocked then it is suppose to fade out. the dome/map light its self works fined off the two switches above the mirror. when you set the one rocker switch on the left to the left position the lights are suppose to come on when the door opens or is unlocked but does not. However if you set the left rocker switch to the right position both lights come on if you set the right rocker switch to the left position just the left dome/map light comes on if set that switch to the right position the right dome/map light comes on . This is for a 92 500sl mbz it is not big deal but I just want things to work as they were designed to do But at this point I think there is more down side to me fixing this then up side. I did buy 2 new UAA 1250 philips chips and I wanted to test them like you have shown but with out the data sheet / pin out I can not figure the dam thing out your instructions were so clear but i think the ground is in a diff location I got frustrated trying to find that data sheet as this IC is obsolete and I just gave up. That was a great video you made and very well narrated step by step instruction. I would really like to test these new chips I am still searching for some info Thanks for your help and video
Hello, and thank you for watching my video. Yes this does work when the IC is soldered onto the circuit board. I have repaired numerous circuit boards with this method of tracking down shorted integrated circuits:) Caution though, on some circuit boards... Sometimes with many IC's soldered to a board, the Vcc to Gnd will appear very low in diode drop. But other than that, yes this works. Thank you very much for watching:)
Oh, one more thing. Don't be fooled by logic inputs that are physically connected to ground. They will appear as shorted to ground with your digital multi-meter. But are intentionally connected to that ground. In this case, look for a trace connection to ground.
Yes I see what you mean. With your digital multi-meter in diode test mode...Place the red lead of your digital multi-meter on the ground pin of the integrated circuit. And place the black lead on all other pins of the integrated circuit. You should see a good diode drop. Or you will see a short circuit on the pin of the integrated circuit.
Peepaw McDonald, this test maybe good. But the real world, my men/women replace the whole circuit board. Working on cameras, cars to electron microscopes, we CAN NOT afford a call back or upset clients.
Hello Sir, I work on electronics that have been assembled from 70 years ago to yesterday. I wish I could get replacement boards all the time. I would if I could. I work on things that have no replacement. They are one of a kind. That is my world. And I do not have men and women. There is only me. If I ever quit this job, I hope that you could hire me. Then I could climb out from underneath what is killing me. HaHa.
Hate to say this but your video need to be really improved. Why didn't you zoom the camera in real close? At the same time, if I catch my staff troubleshooting like that I would fire that person. Client will NEVER pay you even if you save them on the part & charging them $2,500 or more on labor.
Please if you could fire me. I have been repairing electronic circuits for near 60 years. I am tired. I want to go home. But I have 53.2 years more to go before I am free.
@Peepaw McDonald, never claimed that you didn't know how to troubleshoot. Just that you know very little about camera, video & camera angle. Take for example 5:35 (you could have zoomed it in on the chip, if you were a teaching people or showing the viewer), because if you don't many have no ideal what you are doing. So again, the chip respect to the viewing screen. VERY, VERY SMALL. Ask your wife or someone learning, they can't learn because you DID NOT presented the video well.
No worries, someday I will figure out how to get that camera pointed in the right direction. Electronic circuits keep getting smaller and smaller. HaHa. Thank you for stopping by and watching my videos.
In my old age, I wish I could go back to tube circuits. They made much more sense in my time. Or at least, the circuits were large enough for old eyes. HaHa.
Never wouldve expected someone who plays a banjo and goes by the title "Peepaw" would be one of the best teachers of not only electronics but also shares some great wisdom about life from time to time as well.

This is so excellent and helpful! (haven't had the occasion to need to try it but when I do I will come back to this video...)
Fantastic explanation. This works well on old Nintendo cartridge ICs. Especially the ones that won’t save
This is awesome. Thank you. Why would the red lead go to ground on the chip if black is the ground lead?
A short does not care which pin is positive and which pin is ground.
Awesome! Very clear and precise! God bless you!
The most wholesome account on TH-cam I am glad I found this thanks peepaw
Thank you very much for your kind words. I hope that all is going well for you and your family. Thank you for stopping by.
Thanks always wondered how to check these please do more very good explanation tnx
THANK-YOU VERY MUCH SIR, YOU HAVE MADE MY UNDERSTANDING OF IC,S MORE , THE BEST IN GOOD HEALTH TO YOU !!
Thanks @Peepaw MacDonald
Very helpful. Thanks a lot !👍
This is great stuff . But what about troubleshooting an IC in circuit - is it possible to get an accurate reading that way ??
My granddad gave me the HIOKI DT4282 multimeter. And uncle gave me the CEM DT-9889 multimeter.
I believed yours (0.00) and mine are all good.
But I aimed more using the CEM DT-9889 to troubleshoot faster by using the ATG thermal imaging camera.

Excellent video. Could you tell me if you could also do a continuity test between gnd and those pins to determine a short to ground on that chip?
Thanks for teaching us a lot. May you give us a video of all electronic testings?
Can I test the IC soldered on the PCB? Or I need to remove it in order to test it?
why the red is on the GND ? why not black ? sorry for the question ..im just a beginner.

what was the harm in giving colour sign to ground pin by manufacturer
my multimeter on some pins shows voltage drop around 0.1V while others(good ones i think) are around 0.6V or 0.4V... is this IC shorted or i'm just getting wrong reading?
Excellent! I'm going to subscribe.How many pins have to be bad before you consider the IC bad?

Difficult to watch because your camera is set to show everything upside down
Peepaw McDonald i have a question. How do you know the value on each pin in diode mode that we saw on multimeter ?
About .5 to .7 would be ok reading for an if like this.
How do I turn a relay on with the output of photo cell sensor?
Help me?
nice video
God bless!
Nice!
I want a video related to vfd PID control system
I can not see you as you are testing the ic is not clear you have a dark place they
Yes I see what you mean. With your digital multi-meter in diode test mode...Place the red lead of your digital multi-meter on the ground pin of the integrated circuit. And place the black lead on all other pins of the integrated circuit. You should see a good diode drop. Or you will see a short circuit on the pin of the integrated circuit.

i was here 😂
Peepaw McDonald, this test maybe good. But the real world, my men/women replace the whole circuit board.
Working on cameras, cars to electron microscopes, we CAN NOT afford a call back or upset clients.
Hello Sir, I work on electronics that have been assembled from 70 years ago to yesterday. I wish I could get replacement boards all the time. I would if I could. I work on things that have no replacement. They are one of a kind. That is my world. And I do not have men and women. There is only me. If I ever quit this job, I hope that you could hire me. Then I could climb out from underneath what is killing me. HaHa.
Now let us step into the sunset and have a beer. And play a good violin tune. And hope we get up for another day.
Oh, one more thing... never worry about your clients... If you are good... your are good.
Oh, and one very last thing... never ever... ever... ever... forget about those men and women who work for you...I have been forgotten...
And if one thing will ever set you against your men and women. That is being forgotten...
Very useful sir

Hate to say this but your video need to be really improved. Why didn't you zoom the camera in real close?
At the same time, if I catch my staff troubleshooting like that I would fire that person.
Client will NEVER pay you even if you save them on the part & charging them $2,500 or more on labor.
Please if you could fire me. I have been repairing electronic circuits for near 60 years. I am tired. I want to go home. But I have 53.2 years more to go before I am free.
@Peepaw McDonald, never claimed that you didn't know how to troubleshoot.
Just that you know very little about camera, video & camera angle.
Take for example 5:35 (you could have zoomed it in on the chip, if you were a teaching people or showing the viewer), because if you don't many have no ideal what you are doing.
So again, the chip respect to the viewing screen. VERY, VERY SMALL.
Ask your wife or someone learning, they can't learn because you DID NOT presented the video well.
No worries, someday I will figure out how to get that camera pointed in the right direction. Electronic circuits keep getting smaller and smaller. HaHa. Thank you for stopping by and watching my videos.
In my old age, I wish I could go back to tube circuits. They made much more sense in my time. Or at least, the circuits were large enough for old eyes. HaHa.
Still, half a century from now there abouts, I will be free.
