This channel is quite educational. It amazes me how many tv's can be repaired by spending about 50cents on a part! Just need the knowledge and effort.
Add on the experience points... No one ever asked how he knew about how the TV will work without parts or how much better with parts. I personally STILL cant figure it out-huge learning curve watching these vids.
I felt like i was back to the electronics classes at university. I love this type of explanation, asking questions about the solution, trying to attract attention in every single moment of this video. Great teaching.
Hi, sorin I saw older video from 2017(Jvc tv lt-22dg52 no power repair) on this video you have a problem with 3 diode parallel on PSW, and to identify which one shorted you cut each time one diode and the end u are finding the faulty one. but now u are more expriance and teach us better way
People who don't understand electronic assume that a partially, or sporadically working unit is easier to fix than a completely dead unit. They couldn't be more wrong.
They don't understand the difference between a simple DC controller on, say, a toy train and a more complex supply - linear, switching, balanced. Or why that matters anyway. In the above that knowledge and methods of isolating the faulty part kept a several hundred (or more) $ (USD) TV out of the dumpster for the cost of a diode that was likely less than $20.
I'm in awe of the way you work through problems and remind all of us that everything comes down to Ohm's law, Kirchoff's laws, and so on.

You are so kind giving free lesons to people.
U can learn for all your life and still not understand.
But when somebody shows you that the way to understanding is simplicity.
Thank you My Friend....its a pleasure to watch you work..
You are one of my best teachers
This will never get old,thank you Sorin!
Another day another lesson learned from the MASTER teacher, Thank you and God bless you. Oh and Liked and subscribed.
Sorin for King of the free world.
Thank you so much for showing what failed and just how easy it was to trouble shoot. I have a house with no less than 5 Samsungs in it. I'm sure they might end up like this one. You're the best.
Thanks Sorin. Always nice watching you do troubleshooting. Have an awesome week.
Thank you , I just check and my tv have same problem with diode, Amazing is working now 👍👍😀
What a nice way to explain what's going on, how to troubleshoot it using your brain and experience. Thank you!
Took me a couple of times to watch this to understand how you found which set of diodes was at fault. Great video Sorin ! Love the diagnostic methods, and how you explain how it works.
Best on UA-cam !!!
you are very clever :)
Best you know because of you i can fix any power supply you are the master of trouble shooting thats you MASTER SORIN
Thanks I always love watching your videos but mainly the tv ones.
You always give good troubleshooting tips and methods... that's why we love you big boss
Sorin is the Holy Grail for electronic repair😊👌👍
Love your videos Sorin,you explain it pretty good and for a person like me who is not electrically minded it makes some sort of sense if you know what I mean. Thanks for for your time..Good luck mate.
Excellent Sorin I have done 3 with the same issue
Your videos are always the best sir
I have a model tv just like that and I know what to definitely check if and when it stops working. Thank you for the repair tutorial.
Best explaining TV board repair video so far I have watched👍..
Nice step by step explaining 👏.
For me as well, i have a couple of boards to practice on. I cant get 2 channels.
please continue to teach and educate, thank youuu
Thank you for your business, see you again in 2 years.
Love watching ur videos very experienced guy right here 👌👌
Thank you. I have a very similar year Samsung 40” that’s dead. I’m anxious to look at it now I have an idea what to look for.
Sorin the great fixer 🤔!
A master class and no more to say.
you can install sr5100 in this node too. these diodes differ in their operating voltage - 100 and 150 volts, respectively.
but at this point the output voltage is only 5 volts, so the reverse voltage for the diode will be 40-50 volts maximum.
Lots of diodes in that TV!. 😳 Very nice fix. Thank you for the step by step.
Sorin, thanks! This is a nice and educational video!
very comprehensive explanation. 😎 hats off. 😎😎😎
Amazing Maestro Sorin 👍
my best teacher
Amazing as ever Sorin.
Excellent video. Great for putting voltage meter in corner and nice view of meter on components. I subscribed!
great video, thanks for sharing your knowledge.
Hi Sorin, thank you, you are the best.
Nice trick without desoldering thank you
My master, very good teacher.
Ha ha I love it, I have been watching your channel for a while. You remind me of my self when I was working on the TV repairs up until early 90’s. I then moved to the computers and network. Recently I am retired. But I will love and watch the electronic repairs. Good luck with your Chanel. Merry Christmas Sorin. By the way I got my training in the Austria and then I moved to the Canada.
Great video, thanks very much for sharing 👍
Thank you very much for your vídeos and for sharinhg your knowledge.
Thanks for all your videos and taking the time to teach US. Regarding those diodes, they are schottkey diodes and even though One is marked SB and the new ones SR they are identical components.
I have an electronics shop near my house in Portugal and for the SB diode they give me the SR One. Thanks again.
Thank u so much ,you are great .
your knowledge is always mind blowing.
how i like learning
from you. robert young
Good Master God bless you for good work
Thank you sir, you remind me my old work, as a repair technician.
Nice method to find the shorted diode. I did not think that.
But I have to notice that you must replace all the three diodes. They have to be from the same type and same lot also. So they have same characteristics possible.
As you mention maybe the technician chooses not to equalize the three diodes so the TV come again for service after a few years.
Very usefull lessons! thx Sorin
Great lesson.
thank you Sorin
Thank You a lot for this video.
You are Great , i need these videos like air
Thank your Sorin! Pls put value from hot air station on screen. Your are génius.
Thank you very much sorin..
Superb , thanks for sharing
you are using good method!
Thanks for the tutorial. I like your tutorial s.
Your "he he he" in 7:00 is so good 😅😁
Sir, you are amazing!
Great job 👍
Thank you that was good fun
Thanks for this video :) this board has nice look color :D
Send1NStefan I was thinking the same thing. Why aren't all boards like this where everything is so clear to see.
Oh very good more depth here and tricks - well done, subbed. Do more TV boards. :-)
U r my teacher ❤
good job mate.
Been doing some of these myself! It's usually the large 420v caps..... usually.
Thank youbfor sharing my friend
bravo! u are da man! thanks
Thank you master!!!
very nice video
Thank you
I use to love fixing TV then testing them for a day.
tanks sorin
I love sorin he's a fucking legend!
great explonation
Good job thank.s a lot i like you sir
How you got to the fault that fast, amazes me.
I'm improving I instantly knew to put your finger on those diodes to find out which one gets hot (with power being added). Although given we are working with AC I would just wip out the petrol and stick that on instead.
Thank you lot's
That’s the 8 series. I have the same one and it’s badass
well explain
Sorin, thanks for the video!!!
beautiful
Awesome!
wonderfull. thank u
Nice one
bravo
Don't be fooled by diodes showing up short, this does not necessarily mean that they have failed, you can quite easily get false readings from low ohm resistors or even from a local transformer.
He did go through the one set of diodes that seemed to maybe be shorted but upon further inspection he decided they weren’t.
Thank you for your videos. I haven’t been able to watch this one yet. I have a question, is that zippo fluid in the zippo fluid bottle? Or are you just reusing the bottle for something else?
Sir what is the voltage applied to the diod thank you
nice sir
It gets more difficult when a resistor opens. I just repaired a similar PS where a 2W resistor failed open but it was perfectly fine on the outside (not burnt). Had the PS in the TV fully connected and plugged into mains, and traced voltages with the aid of the PS schematics. The issue was the PS not switching although rectified mains was there.
On diode mode, aren’t good diodes supposed to show “OL” one way, and some +/- 0.500 number, the other way? At 12:10 you got a reading of 0.250V and 1.555V the other way. How is that diode not damaged. Please explain, I’m a novice. Thank you
Super! :)
Awsome
