You had my curiosity, but now you have my attention

This lesson was the most spectacular of all I've seen so far in electronics (and I've seen a lot, but it seems not enough). Sorin, you are a genius, man, keep it up.

Everything was done perfectly. Without advanced knowledge of electronics such a thing could not be done. It's great to be able to see something like that.

I did this recently with an old laptop power supply to power a 36" LCD TV. You should get yourself a Dremmel tool to cut the PCB. It's way easier.

I love this video. It has everything. Sorin, knowledge, dodgyness. I love that you show us all. Spliting the board in half without proper Tool. My patiece will be after few seconds. And next that troubleshooting. You Are amazing sir

Wow. Patience and persistence pays off. Can't tell you how much your methods help...and I apply them to many things in life.

Well, this is a clever and fast way to make a working power supply. Sorin you can find electronic load tester even on ebay very cheap. With that tool you can test and bechmark the DC power supply. Excellent video Sorin!

Thank you so much for showing us how great you are and for this great lesson of how creative you had to be in the older days when parts were not easy to get ... what a great lesson on how to make what you have work you are a great teacher and thank you for showing us.. your knowledge is very much appreciated ...

My hero is back! A true mentor for shares lessons they've learned and knowledge they've earned.

Amazing!!!! Thx for this video Master Sorin...when you plugged the music and it started playing....Woow...that feeling, just made me smile

Sorin is the "hero tonight" for sure! :-D

Thanks for this vid. I'd never thought of this way of fixing a switching power supply. Haha, next time, I bet you won't forget to test the amplifier part by injecting power from bench power supplies, like you always do. You would have found the shorted capacitor. And next time, just cut everything off the hi-voltage portion of the board. You'll have a nice surface to glue the donor board to and it's way faster than trying to break such board in a certain line. During testing, you actually had a ground. Your computer and the speaker both have earth leads. If not, it would have sounded way worse. Dodgy? - Yes: Those tiny red patch wires are not rated for 300V. They were sitting against the bare cooling plate. Insulation might rub through, due to speaker vibrations. Hot glue might melt if this amp is operated for a long time at high volume, outside, in this weather. But still not more dodgy than the average chinese ebay product. Keep up the good work.

i don't care about time when i am learning sir. thank you so much

The way he is able to think outside of the box is amazing 👏

You sir are a animal. You do not accept no for an answer. Bravo!

This guy is magic. Even his videos. I was watching this and wondering what he was going to show with his microscope. As he turned it on the adverts started on KZread. Magic Morris. Great videos. Thanks.

I apreciate when you said " With the knowlege freedoms comes" and i understand you , you are right Mr Sorin and on other side of the video you showed your knowlege in electronics and experiences , then you was free the define the stragery and you reached the goal

Amazing as always, every time i watch your videos learn more and more about electronics and repairs. SUCCESS, THANK YOU. BRAZIL

I can't believe what you did over there 😮 Realy you are hero 😎👍👌 I wish that I live near to you, and take all that knowledge from you master 💐

100 likes , Thank you so much , I hope from people who see to give you like for the effort you make for us and you giving us your best great experience of you .

thumbs up for not giving up and for dodgyness keep it up sorin

You are just a star Sorin . Keep it up

Great video again Sorin. A small fret saw is what you need. It has a round blade almost like a rough file and is deep. You would of been through that in a minute. £10 on ebay.

it is just great i love it.. very nice modification.. keep your good work sir..

I actually like this dodgy Sorin style. You gotta be savage sometimes 😎

Nice work. I love it.

Nice and helpful repair video

Bloody brilliant Sorin, conquering hurdle upon hurdle with style, confidence and wisdom. Thanks for sharing :)

it seems like Dr Frankenstein somebody needs to invest in a dremel.. lol 😂🤣

Great videos. Many thanks. Would be good to see the multimeter readings on screen when you are testing the voltages.

lol you transfer signal music in your hands x) super nice job

It is stated that we all have just seen a live post mortem. 😁 amazing video ❤️

lol Finally I know that I'm not the only person in the world who strips wires like that ;-)

A 6mm audio jack fits into those XLR hybrid ports....too funny when you tested amp by shorting inputs with your screwdriver!!!

Hello Sourin, how you do is very well, and thank you very much

Whilst I admire the ingenuity of the electronics knowledge that went into this fix and would do it for my own stuff, I'd personally be a little wary of letting this go out to a customer - you've just documented what you've done on a public domain, which, if the worst happened would highlight the method and what was inside - nice to share but make sure your business has its backside covered ;)

That was mad! Love it!

Great job!!! Foarte tare!!!

Extremely interesting video. Many likes.

You had me at "Frankenstein"

Biting the wires off when you have a soldering iron in your hands. Heat the end of the wire with the iron and then use your thumbnail and easily pull off the insulation at your desired length. Or use a lighter. It's a very fast way to do your ends.

Great job,Sorin.It will be so nice if you explain this method furthur in another video.

Brilliant piece of firefighting excellent job well done👍

watching your video in the morning and boom earthquake i had to flee in the moment ha ha ha greetings from mexico

Wow, awesome content!

Love your videos

Hi Sorin, I wish I could send you one of my small tools to do that board. Don't give up my good man.

The power supply chip is UC3845 and the KA2 SOT-23 smd maybe is 1N4148 diode.First clean all the fumes and then try to read the circuit and components value and in most cases the circuit is exactly the same with the datasheet of the power supply chip.

that was simply amazing

What microscope do you use sorin? These videos are my favourite thing I've found online. I've been fixing computers for 15 years but not at this level. You've really brightened my days!!

Hey buddy. From what I gathered from observation is that these audio sockets also just take the 1/4inch trs in the middle.

i think the video was great. i like learning ways to improvise. the supply may not always be easily available and this can save your behind. i would recommed using a dremel though to cut the board. haha

Sorin, did you go to school to learn this or are you mostly self taught? Your right.. Dodgy is when someone that is not really sure what he is doing, tries to cobble together something that is not only unsafe but probably won't work and he doesn't know why.. and a lot of time hurts himself in the process.. This was great! to watch you as you worked through each step was priceless. It is a good example of the critical thinking skills that is so badly needed in this world today.. thanks.. please carry on!

The beeg one is an XLR connector. It's a balanced connection. So what does that mean? Let's say you are setting up in a nightclub or concert environment. You may have a very long run with your wires and guess what there's probably a bunch of other equipment lines run all over the place too. This is an high electrical noise environment. Enter your balanced connector. 3 wires, a ground and then your audio signal and then a copy of that signal but out of phase. This is like noise cancellation headphones. Any noise on the lines that isn't your signal doesn't get amplified. They charge the shit out of people for this stuff and it's probably a few op amps and comparators. I saw one company asking for $300 to add XLR to your amp. You can get kits for under $10. So they are just taking advantage of people. If you aren't in a situation with crazy amounts of wires running everywhere and lots of electrical noise, you do NOT need balanced connections. Home users don't need this. Don't pay Monster Cable $300 for a 3ft chocolate HDMI cable either. Holy foolishness. This was an interesting video. A bit cringe but my dad who was a shipfitter in the Navy would totally approve. You make due with what you have. It's like being on an island, if you don't bring something with you it's not there.

This is not only a Frankenstein repair, I think you ARE Frankenstein, HAHAHA! (This gives a new dimension to the word 'dodgy' 🙂 )

Thank you!

U should open a case bro! Otherwise many people will be scammed

I thought the transformer had to be designed for a specific input and output. I guess the switching cycle takes care of that and the regulators on output make it work. But surely you cant mix and match all kinds of halves of smps. Great video.

Nice video

Cool fix.

many thanks, sir .

Nice air-gap between primary and secondary. Much safer now. The German TÜV approves.

Wow! The Old Man is back! We love your work. Sunny Greetings from Germany

Frankenstein method...Love it....

Awesome fix mate I have done something similar when 5v was missing and i used £2.99 standard wall charger lol

I'm sure the guy from Northbridge Fix would do exactly the same job but it would look better than factory :))

thank you sir

That isolation gap is now better than factory 😅

Good work true genius 🎉🎉🎉

dogy?.. i call it repaired and customer will be happy to have it back...never too long a vid when you learn things as you have shown...... lol..i stick at something till the last dog has died...well done

thank you

i saw this kind of technique before. When one side of psu card doesnt work, they break card apart and use sturdy side.

UC3845 is a classic current mode switching power supply controller IC. you probably just typo when you couldn't find it.

This is dodginess taken all the way up to eleven.

Why? Nice air-gap between primary and secondary. Much safer now in case of liquid damage, e.g. heavy rain during an open air concert or event outdoors..

thank you M.r

Few things to watch out for, you connected both half's with silicon, ... well, if the board heats up and the silicon melts then both parts would land at the metal chassis causing a bigger problem, or electrocution !... The wires connected between the transformer and the secondary board are not thick enough, they can heat and cause a problem if their insulation melts. I usually like all your videos Sorin, not too sure about this one.

@nricu3604

The wires are not thick enough... maybe you are right! For sure, I will use a thicker wire only to be sure but on another hand, the current on this wire are not high as I believe the speaker unit has maximum 25-30W. The voltage is aprox 300V, so the current will be aprox 100mA. My concern is for the Switching Transistor which has a big chance to overheat as it has a very small aluminum radiator attached too. All another voltage regulators and audio amplifier are connected to the big aluminum case....

@@nricu3604 Hi Nelu (Sorin?!) ... thank you for your reply. Well, when it comes to AC for speakers it's not just (W = V * I), you also need to factor in the 2-PI-R-C calculations, the reason is to do with using "frequencies" here, higher freqneicnes can give the effect as-if it's a much higher power travelling through. For instance; Audio (which can go up to 96K higher frequency than DC=1F) can change the impedance significantly, which may result in much higher current pushed on the same wire, this causes overhearing i.e. using 30W for DC is ok for 1-2ml wire thickness, but for AC (audio) would definitely require a lot thicker due to higher frequencies and lower impedance, ... Try to imagine or think about why passive speaker cables are about 4mm thick at least with a very small voltage across (I have my Dolby system connected using the Sony STR-DA5600ES receiver to all 9.1 speakers with a 4mm cable thickness as recommended by Sony when the voltage is less than 5v anyway! I hope I am making sense, happy to discuss more if you like, thank you again for your reply.

@@HeiderSati - Thanks for your reply but I am not Sorin.... I use to do repaire of electronics 20 years ago... was a hobby but also making small money during the school. I learned by my self since 7 years old... Even now, I still repaire and modify everything comes in my hands... but of course I can be wrong and I still can learna lot... still room for improvement😀. Anyhow, you are right regarding the the AC and Audio signals. In this particular case, the wires were used to connect the switching board to the transformer. The voltage here is about 350V (after the 220v rectifier & condensor). So the switching voltage is over 300V. This will require a very low current to produce 30W power(DC). Also, this curent is not permanently ON as it is switching on-off as required, so the heat production is not permanently even that the curent is getting higher (maybe double) for few milisecunde. Overall, the input power will be only slightly higher then the output power. Also, if we take in consideration that the Subuffer uses a Class D amplifier, the require power will be even less. What I want to say is that, most probably the wires will be thick enough (maybe 0.5mm diameter) to power this particular application but for sure, personally I will use much thicker wire for this job.

Hi sorin first i want to say thank you for this big lesson but how you cant see the aux in input !!!!

Sorin, we must be related. I am accused often of being dodgy, but current 'use once and get rid off if is broken' generation don't get that sometime something can be fixed. That include PEACE too. PS. You need a Dremel (I could not watch how you have been cutting that board with sharp tools) and a thermal camera. 👍👍👍👍👍👍

This is the best way to do it because you know that the primary is 100% ok and the secondary 100% as well. Nothing to modify thus 100% reliability.

hi sourin from syria with love

Im now looking for chain saws online as a new tool for my repair shop

Sorry but I Cannot Fix it but NO SIR Sorin CAN and WILL FIX IT why he is the MASTER REPAIRER on the Scene

Hi Sorin , Wether It's simple, dodgy Frankenstein electronics. Could be life or death on a sub if you got it wrong. Respect.

Sorin! May I suggest you use a rotary cutting wheel on a dremmel next time? :)

Great repair! Dodgy? Well probably the dodgyiest repair sice the Dodgy Borothers ran the dodgy repair shop in Dodge City but that is one of the reasons I come here! We don't see lewis repairing macbooks like this! :-)

nice to have....an Dremel Tool :-)

a m a z i n g.

@sorin i think the 2 amp fuse is ok. because from primary side of the transformer [ high voltage (240v) & low current (2A max)] and on the secondary side[ low voltage (42v) & high current (5A)]. It rectify high voltage(240v) ==> low voltage (42V) low current( 2A max) ==> high current( 5A max)
