I have the exact same speaker with the exact same problem, watched this video, ordered a replacement diode (plus a few extras), then fixed my speaker in 15 minutes. I stored the extra diodes in an antistatic bag inside the speaker housing, in case it blows again. thank you so much, sorin!!

[@tenmillionvolts]

Your techniques are so much like mine Sorin. I have tried several Shottky diodes until I got power supply working and repaired flexi cables in the same way too. The people hating the videos don't understand that we have time and money constraints these days. You used to be able to order the correct part and wait for it to arrive ex Japan/ Europe at a high price, and the customer would accept that most of the time because the equipment was expensive and desirable. Now they will pay you nothing, want it fixed quickly and are happy to put it in the bin if you can't do that.

[@esspe2]

"Carry on”... Great advice! It is so tempting to give up at each fault, but that's what makes you win in the end.

[@leapy3377]

Long time supporter here, I am unsure if you will read this comment Sorin, But I have to say I know you might think it is a bit boring for us to see the same jobs over and over again but It helps us greatly and we like you as a person also!, Shop workflow is honestly something I super appreciate and would love more of as I am heading into this industry and its amazing to see the different types of jobs!, keep up the great work sorin.

[@kennymanchester]

IF I were to somehow find myself on a spaceship that encountered an electronic problem, I cannot think of a better person to have onboard than you! Nicely done, and especially on improvising the connector and ribbon cable repairs. Really well done.

[@deft3562]

Your passion for giving lesson remind me of my teacher at elementary school which was amazing and sincerely, so as student we always eager to learn. God bless you mister and family🤗

[@vasileiosmarinis2698]

You are the best sir !!!! the gloves the big words and the fantasy tools doesn’t makes any one a good technician..... The way that you explained the thinks is awesome... I’m doing for years this job and you have my respect some times I feel so jealous you are genius old man!!!!! Thank you god bless you!!!

[@Kreska0]

So many videos uploaded this week ! Thank you ! 😀

Sorin vs Sony 2 : 0 . Thank you for this video

[@davidbegin2239]

I greatly admired the calm you had when all those problems appeared one after the other, you might have cut your finger but you've solved this like a pro :) this job was really interesting to watch, Always a pleasure learning with you.

[@TheFlyingKiwiNZ]

Thanks so much for such an informative video! This must be a common issue as the same diode D1 was also shorted on my speaker. A quick trip to my local electronics shop for a new schottky and a bit of soldering and voila! the speaker is alive again! Saved me hours and hours of scratching my head.

[@02sector]

Foarte bun, se cunosc anii de experienta ! :), multumesc mult !

Great idea for the channel. Greetings from Poland.

[@computersrepaircotesaint-l7407]

We just love our master teacher

[@ecobob101]

I've watched the first Sony video 3 times as I've learnt a lot from that. I even watched it last night, which is why this has prob showed up in recommended videos this morning. Got coffee and cheese on toast to watch this, kids are out ...bliss

[@ecobob101]

UPDATE: Just finished and it didn't disappoint. Love the smile when it worked at the end! Now off to T-shoot a t-con board on a computer monitor. Regulator dc-to-dc IC getting hot but hoping it is a cap (or diode) or something else near.

[@nickhardiman2142]

I recently found this chanal. really like and appreciate all your videos. Please keep up the good work. All the best

[@oliverkorsten7744]

I would like to say thank you I am learning more and more every time I watch one of your videos keep on going 👍

[@geovani60624]

i once tried to remove the plastic from the flex cable using my soldering iron, it destroyed it, in the end i used a 400 grade sandpaper and it worked fine

[@invisiblebike99]

Between this channel and AvE's channel you can learn so much about how consumer electronics companies build things, and how to fix those same things. Almost everything you buy nowadays has electronics in it.

[@NeuronalAxon]

Louis Rossmann's good to watch too, I find - not just for fixing Macs, but his life/business videos are great watching IMO.

[@silviuguseila2552]

what is AvE's channel?

[@seckinseckin3919]

AVE channel ?

[@climberakis]

Learning so much from you, thenks teacher !!

[@onderol]

Thank you Sorin. Probably using your solutions who hating your solutions.

[@itsmekennyd]

Great video so history I started working on computers in 1990. Ended up switching to a electrical field. They I delt with only automotive computers and moudules. Due to heath issues I'm getting back into board repair services again. It all goes hand in hand. Electrical is electrical voltages range and design changes. I enjoy stuff like this but we are in a throw away generation and it makes it hard. On a good note people will give you stuff that don't work. Enjoy everyone and if you mess up just learn and go on. If your just starting work on your stuff so if you burn it up it's not as bad.

[@medonryngkatmarboh3484]

love your every video man, much love n respect

[@richarddurose7153]

I would also suggest a Dremel with a sanding or polishing attachment to clean the plastic on the ribbon cable is a lot safer on the fingers and easier on the ribbon. Really a Dremel is an indispensable tool, like hot snot glue, every bench should have one..

[@electronicdiy8544]

Your skills are really amazing sir😍😍

[@oswaldfraser4946]

You have made it very simple,thank you

[@Radek__]

37:29 I'm happy that you did it in the RIGHT way this time :) Now I can be proud of you. (I was the one of haters, on that older video :P )

[@DestaForsido]

wow you are Best teacher of electronics i like you . you stayle work every thing you are my best i follow you

[@greengrayradio1394]

To work correctly in a switching circuit, the diode's recovery time is very important. Compare this in the datasheets, it should be as low or lower than the one you are replacing

[@NeuronalAxon]

Do the common ones have a large range of timings?

[@msubtech84]

@@NeuronalAxon If I remember the voltage ratings on the Skotchey diode affects it's switching rate....maybe I need to look that up again I am just stabbing in the dark.

[@maryjaneevadiamond6359]

Just remember that shotky is fast. Switching power supplies can work on different frequencies. When you imagine a DC to DC converter, technically it's a DC to AC to DC converter and if the frequency used in that switching circuit cant be completely rectified by diode or bridge rectifier then the voltage will be LOWER because its going to miss some of the cycles. Hey, next time you put in parts from donor boards you CHECK parts first ok. 🙏 And good job by the way. Flat cable fix was amazing.

[@weerobot]

Awesome Video again...how can people dislike??...don't they understand the Work/Cost ratio...??

[@aszandek]

Wow, that was impressive. Thanks!

[@1b4dsrt]

I fixed a Lenovo laptop motherboard because of your teaching, thank you so much.

[@NeuronalAxon]

Eh, well done - what was the fault, and how did you fix it?

[@paulodagraca3469]

Great to see you are right! AGAIN 😀

[@1212windows]

Satisfation when it is done!!

[@johnoddvar1967]

You can measure the schottsky diode with your diodetest. It opens at about 0,2 volts. A Normal diode at 0,5. It is not good at high voltages and it have a bigger leak in reverse direcsion. You find them in the secondary on the swiching powersuply. They are as here very fast. Thank yo for a nice video.

[@zyxnull]

Amazed to see Sorin's video recommendations look a lot like mine

[@23BeRAD]

If anybody gave you a hard time about that other video then they don't know what the hell they're talking about. Well done, and I'll be doing this same thing shortly. When one of mine blew out I had 2 next to each other and I was pressing the party chain button and add speaker buttons on both at the same time and that's what caused one of mine to go bad. 🤨 this happened a year ago or more and your video has taught me everything I need to know! Thank you

[@donald1056]

Having that red wire connected would make a major difference - not easy taking that plastic off that solder wires but you did it - good work - you fixed 3 different problems - put some rubbing alcohol on that cut and you'll be alright - that's what I do

[@g8sbs944]

ALWAYS check for main Power FIRST then if need check power Supply in logical order till you you find the Fault k

I use the same method for fixing flex cables, i just use scalpel for clearing the copper.

[@ShadowKrutshov]

How many here loves and are passionate like this about their job? Raise your hands..... NO! Not you Sorin! LOL

[@hippynurd]

could you measure the voltage drop on the donor diode and see if its a schotkey?

[@m.ermanuruk4941]

Your videos are great and full of knowledge but if you cut the parts that's not about the video before you upload like customer time or your phone calls it can save us some time. Thank you and please keep up the good work !

[@lucianoinformatica]

Sorin, excellent video as usual. I know you´re a busy man, but I´d like to ask for help. I have here a Samsung NP550P5C laptop motherboard, but it doesn´t power on (it´s dead). I have 19V power rail all over the board, but doesn´t turn on. The only way to turn it on is when I inject 3V on TPS51125 (pin 13) EN0. When I do that, TPS51125 gets VREF, VREG5, VREG3 which generate VCC for EC. The power LED light up, I get 3V on the power button, and when I press power switch the board turns on. The board works perfectly for one or two days, but after that it´s dead again; no LED at all. So I have to disassemble the laptop and inject 3V on TPS51125 (pin 13) EN0, and the board reborn again. I don´t know what to do. It´s beyond my skills, so I count on your expertise. Thanks a lot Sorin .
