I’m an Environmental Engineer who did electronics projects and repair as a hobby. After graduating I was struggling to find the right job. Videos like yours helped me a lot to learn electronics repair. Now I work as a Service Technician for environmental instruments and get paid like an engineer :) Cheers!

These videos are a wealth of knowledge that’s very rare. I started following you back when you had a few hundred subs and your channel has stood out.

I believe you have had formal electronics education (an engineering bachelor degree? or masters?) and industrial electronics technician career?. But most importantly you have a passion for actual electronics and learning!

There are plenty of electronics projects and electrical engineering channels but I’m not aware of many other channel that fixes a wide variety of electronics from laptops, GPUs, psus, etc on a troubleshooting and analytical level.

Just about every other repair channel either specialises only one type of device
Iike a phone or a laptop or MacBook alone or they are only soldering channels In the name of repair.

We always learn something new, who cares how long it takes . I’m just glad you show us the process.

[CTCTraining]

Very logical approach.. might have been interesting to see the behaviour of the circuit with prior to replacing the cap but the visual check was spot on. 👍😀

[pcwrangler]

Great content as usual. Love these! Thank you for all your effort.

[WoodDivisionSupp]

Great content. As the subjects taught by my electronic engineering degree fail to supply me with the knowlage to create and repair circuits this channel has been a great help in supplying me with the type of content I want to learn. Thank you for uploading and keep doing what your doing!

[hullinstruments]

Oh hell yeah! So glad to see another one of these. I haven’t been this excited for a video since Schindler‘s list.

Great video, normally those PCBs are covered in an inch carpet of dust lol. The machine has 2 goals which are monitored by opto sensors and has a solenoid to stop the puck when the time is up or the score limit is reached. It also uses a set of 7 segment LED displays each side for the players score. There is the coin input which will finish off the purpose of the opto couplers going to the 3 small black connectors. Other than that it plays an annoying tune and has speech when goals are scored. The air pump kicks in as soon as the coins deposited reach the price of play determined by the dip switches, and the puck is released then too. Intrigued to find out why there are 2 motor drive chips though but I would imagine that the capacitor may we'll have sorted it. But bear in mind that the PCB probably was wrapped in a quilt of dust/carpet fibre so it may we'll have been running very hot, the customer never tells you that bit 🤫. Hopefully you won't have to go to site as once you heard the annoying tune it will be with you forever 😂🤣😂

Great video, can't wait to hear the follow up on this one.

[Dutch_off_grid_homesteading]

Heya, great vlog again love to see differant pcb from all kinds of applainces learning a lot like this thanks

[KBUIF]

Hi Rich, That 5Volt reg you said you were going to replace, you said was giving out 5.6V but you measured 0.6 on the reference ground, so it is actually giving out 5V correctly above the 0.6V ref.

[surgingcircuits]

I just took on a similar project repair, so was very helpful. Thx!

[MrProtector]

thank you, we are very lucky for your time, regards. 😺

[Michskater]

Again… he bent the probe 😂
Perfect video, thank you for the good and very helpful explanation. I love your videos!

[felipehernandezhernandez]

Que buen video, en los años 96 al 2002 repare muchos air hockey arcades, buenos recuerdos, saludos desde MEXICO

[garypoplin]

22:11 - You may be right about that. Some of your videos show you probing pins on a small chip by bending the probe as far as you might pull back on a bow to shoot a deer from 300 yards. Thanks for sharing all your _other_ techniques, though.

[leandronavarro]

Where can I find the first chapter of this? I absolutely LOVE your videos and I gain a lot of knowledge thanks to you sir. Salute!

[coxyofnewp]

I've learnt so much in the last few weeks of watching your vids.. Great work.. And I look forward to going back to watch your other vids too, while waiting for your next ;) As for this - be nice to see a catch up vid to see if it was the Cap causing the probs etc..

[andymouse]

I think its fixed, nice bright LED's and a resounding click of a relay certainly now is a good time to plug it into the game and confidently blame the cap !....cheers.

Hey, great videos. I’ve been following your repair videos, trying to learn electronics repair to help me find the problem with a faulty board from a machine at work. The board is made by kuhnke, a controller for pressure beam on a sandpaper machine, and it uses CAN communication. I haven’t been able to find something’s faulty on the board but There are 6 such boards in the machine and one faulty one among them affects the function of all of them, but once you take it off, it’s fine, that makes me assume it’s a fault on the CAN control part of the board, but I have no idea how to proceed. I would love if I could get any form of info that could help.
