Pure Electronics Repair. Learn Methodical Fault Finding Techniques / Methods To Fix Almost Anything

😍Have a good day , awesome video 😍 Love from Pakistan Subscribe + Share + Like ~

Thank you
!

Excellent work , all the best and keep it up...

Just beautiful 👍🏻👍🏻👍🏻

A mate of mine is a gas fitter & he says it breakd his heart judy throwing boards away because his firm just send him in with replacement boards and he told me how much they cost even for just refurbished PCBs.
After I picked myself up off the floor he rummaged in the van & I've now got a box full of faulty PCBs.
So I'm after learning. Step by step is ideal for me (Asperger's lends itself to methodicalness) snd I've just discovered your channel.
To say "I'm all ears!" would be a massive understatement.
😀☮️
Edit: Loved it! Absolutely blindin' mate! That Peak Atlas would pay for itself on day one.
I was looking at a cheaper one but the Atlas didn't invent 2 resistors. That sort of thing could throw you off at the start.
Ok, off to watch another. Subbed with a head full of ideas! Nice one! 😜

S,v

Does anyone know how to find a self employed electronic repair person? Many factories would be interested in this skill and the service would be extremely useful!

Eager to learn. Very basic level. Thank you for all you do for us. Subscribed.

Hi I wonder if you can help me i have a electric fire with a lcd display the display of various flames etc. it is generated from a sd card the picture pixelates / stops / starts etc the pcb's consist of a power supply / a main card and a smaller card and the card for i assume the back light. I have tried a couple of places to get it fixed but no joy. the parts are no longer available the display is good in the sense that the flames are from videos of real flames, Modern fires are all flickering lights only (not good). is it possible for me to send you the main pcb and see if you can fix it the fire was my sons who passed away last month from pancreatic cancer and i would love to hold on to the fire, pcb approx size 4" x 5". some one lent me their pcb and that is the problem. I live in Aviemore Scotland Thanks Robert Paterson

It took me 20 min to get used to his accent. Nice video though.

Pigeon 💩 lol. Great content have been doing electronic repair in industrial machines for a while and was glued to the video

Guy is all over the place in this video

❤❤❤

Thank you for a great tutorial. Much appreciated.

I can't believe this is my second time watching this one. It's actually very interesting how easy Richard makes it look.

What a lesson! Graduating as a mechanical engineer, now close to retirement have found the world of circuits and electronic components which is plenty of fun.

Thank you

Machine in Italian is spelled, macchina, no macina!

I think your "rant" about how to be intelligent operating an electronics repair business and targeting industrial equipment was very valuable and not a rant at all. :) Thank you for all you do!

Hi there, I have basic electronics knowledge, and I spent my afternoon and evening trying to figure out the broken part of a device and I have some general questions (no, it's not a GPU :D it's an "Omron M400" blood pressure monitor made in Japan).

The device is 6V DC input but it was connected to a Laptop charger that supplies probably about 19V. My question #1 would be, what do you think blows first if you supply too much voltage to a device? It probably wouldn't be a resistor or anything, would the CPU get fried most likely, or? The connector doesn't seem to have a fuse, as it does supply power to the circuit board with all the button inputs yet, as well as the main board, but nothing turns on anymore (i. e. main display or LED indicators). I was told everything had turned on with the wrong supply, but the display and LED were displaying erradically and then it was disconnected from the power.

My other question would be, I saw you hunting for a short circuit by measuring resistance. My Multimeter doesn't have a beep to check for a connection, so I used measuring for resistance. No signal, no connection. Signal, yes connection, but at some resistance at least. I'm guessing a short circuit where one shouldn't be, shows by having low to no resistance, is that correct?

In either case, thank you very much for your videos, I've always been highly fascinated by electronics repairs. I haven't seen any visual faults on any of the boards, and I'm not ready to give up on it yet.

What about the burnt spot on the terminals? That’s okay to leave as it is? You would not bother cleaning it at least?

Are these video made to waist our time. I lost interest in the first 3 minutes with all the waffling on😢

Pompa is for pump - sometimes they stick (the pump that is )

please less background, more fixing.

Great video tutorial ❤ thank you for sharing your knowledge and experience 🇵🇭🫡

Macina in this case means grinder (it's a coffee machine)

It's Italian not Spanish

First time watching your channel. i will be watching some more, nice job, great vid. Time to learn some more. Thanks

Thanks a lot! As a mobility aid repair tech trained up in the field, but having no background in electronics, this is very useful getting my head around the deduction process in fault finding...
I think I'll have a snoop around your channel to find more of these gems...

Macina is Italian for Grinder.
Nice video btw, as a newcomer to electronics repair im going to subscribe and probably watch all your vids so thank for the lesson sir!!!

Where's the Analog Devices evaluation board from the thumbnail?

thank god for captions...lol. great lesson though. 😆👍

Thanks for sharing!
By any chance do you remember if the heating element was actually shorted when you returned the PCB back to them?

You are master! I repair my Keyless Entry Receiver in my Jeep thank your clip! Electronics is black magic to me. but according to the methodical fault finding I checked the paths from the connector through the board one by one and found breaks! I soldered the corroded elements and it worked!

I was left uneasy about what seemed to be an ignored metal layer near the 1/4 inch tabs. My reaction would be that it is quite conductive film frozen from the vaporized metal during something arcing. So, what was the arc? Wast one or another connector loose? Based on that, I would be suspicious about the wiring outside of the board in this area.

thank you, what an excellent teacher you are, thanks for sharing your knowledge with us 🙏🙏

Thank you, this video was very helpful to me in understanding electronics repair. I have a Mac classic I've been working on, and it will only boot if the voltage rails are lower than their correct voltage. This has helped me understand the troubleshooting process a lot better.

So A puzzle for someone- item that always fails after 6-12 months,but we keep buying them because the knock-offs are even worse- Apple lightning to digital av adapter- a simple dongle that enables user to connect iPhone via hdmi to TV and mirror almost everything-fantastic for cord cutting penny pinchers- BUT!!!!!! Check the reviews, worked great and then failed-it’s ridiculous! Are the tiny wires failing is it melting inside? I’ve purchased 5 over 8 years- they are $40-50, but when working Fantastic! Streaming movies etc from the phone to the big screen! All you need is unlimited data and a strong cellphone connection! Until….. it fails- everybody has the same damn story eventually! WHY OH WISE ONE WHYYYYYYYY??????

Oh this is easy you can see dark roast parts on this board😅

you in worksop or retford? or there abouts? its the accent.

So sorry to hear that I lost my dad two yrs ago to cancer but the system in the UK is wrong I know what you wanted to say someone can pay into system all the life then if they go in a home or need 24h care they have to pay for or sell there house so there kids get nothing, But those certain people just come into country and get everything paid for rent money to live off, paid nothing into system about time government got it sorted now, sorry but that's just my opinion,

I can't understand what he's saying.

question for long watching of this video may i ask what is the setting of tester

hard to follow for a non skilled person. For me (not the smartest), I need to understand when you use a meter what your connecting with each lead and explain the meter reading. Perhaps I'm not the audience here, but if you say something is shorted or not shorted then what helps is if you step through an explanation of why you're declaring it as such.
Again, my ignorance is a problem here, but when you have a pcb with silver tracks, larger copper/gold areas beneath/surrounding and then the green of the plastic board it's hard to understand how you're tracing component connections. Thanks for the video in anycase.

I'd connect the PCB to low V @ 1.0 and use a thermal imaging camera to detect overheating components (a short).
As well as a DMM. In the HVAC industry $300 PCB is thrown out daily.

Aqui lo qie toca primero es verficar el buen estado de los componentes 2 ver si hay decoloracionen la plac por sobre calentamiento verificar los componentes de salida lineas de alimentacion y fuente B+ en cualquier placa pero lo mas importante es cobrar

Thank you very much, Uncle Rick for your explanation on how to look for fault on Catering/other Business Repairable Machines... Utility Machines..

Good sir, thank you do much for your wisdom and knowledge. Being many years junior to you, i really appreciate your expertise in the field. As an EE, you definetly made me decide on starting electronics repair as a side job. All the good to you from Kazakhstan.
