Excellent video. Measuring voltages is a qu8ck way to find the problematic area and of course, voltage injection is the best method. I normally use alcohol to see it evaporate but the thermal camera is a must to speed up the repairð...thanks again for sharing your knowledge and skills
There is a very easy way to identify a bad SMPS in Samsung led TV's. Just open the power connector from the mother board if the backlight glows then the SMPS is ok , fault in the mother board. My next suggestion is..... To identify a faulty capacitor or any shorted parts it's better to use a regulated power supply. In your case the capacitor is connected to the 1'5 volt supply rail so at the time of injecting voltage ( more than 1'5 volt) if the capacitor gets open the other components may have affected. So it's better to use a regulated power supply and start pushing voltage from 1 volt . Otherwise it's a nice video brother and best wishes for your next repair.
Mr dear tevz. It was a nice repairing of smart tv samsun! I really enjoyed. It too much Be cos finding a short capacitor is usually hard but you did it as soon as was possible. Well done.
😍😍😍😍😍😍😍😍😍🤩🤩🤩🤩🤩🤩🤩🤩🤩 NICELY EXPLAINED..... EXPLAIN IN YOUR STYLE. ITS EASY TO UNDERSTAND FOR THOSE PEOPLE WITH NO KNOWLEDGE OF TV BOARDS AND ELECTRONICS.. SIMPLICITY IS I LIKE IT
What pin on the connector had 12.8 volts stable at the begining?? The connector diagram says 13v on all except the two gnds I'm totally confused. What voltage is PSON meant to be? What voltage is the UD meant to be? What voltage is blon meant to be? I think the geeks that design these things are trying to confuse people utterly.
Hi Tevz, I wanted to ask something. The shorted voltage line was 1.5V You used an external power supply to figure out where the short is. This voltage was 4.1V.. The voltage was much higher than the design voltage. Luckily the short pulls this 4.1V low. If however while fault finding if it was possible for the short to go open circuit I guess you would cause damage due to over voltage. Am I right?
You are right, it is lucky it did not open the shorted capacitor. The power supply I use is not regulated, if injected into the shorted line it will drop at about 2 volts but still higher at .5 volts. But the TV works fine despite it being injected with a higher voltage.
@tevzTVTevatronics if you had a variable power supply that could go as low as 1.2V that would be safer since mainboard could core voltage is around 1.2V and there is no voltage lower than that.
It's very unlikely that any component would get damaged even with hundreds of volts going through them if very little current is being drawn which is not possible by design but it is possible to regulate the current you inject and would automatically regulate the voltage by dropping it due to ohms law.
Interesting method to find the short. I've seen others use a thermal camera, alcohol or a flux mister but never a candle. It's a lot cheaper than a thermal camera! Do you use an isolation transformer when powering TV's? I recently tried to repair 2 OLED tv's that would not turn on but they seem rather complicated since now they allegedly use software to match the boards. Wish I could find a course on troubleshooting them.
9:53 there is SMD diode looking cap C1265 right next to Ceramic capacitor C1252 that you removed. Is that C1265 capacitor? It looks like a diode. It'S Black rectangle with a stripe on one end. I never seen a capacitor which looks like that.
Hi engineer Why did you doubt the mainboard after the instability of the voltage in the power board was determined? If the voltages on the power board are not correct
First time I have seen a TV repaired with only a candle and side cutters! 🤣😂 Great work Mr Tevs!
Thanks again!❤❤
Благодарю Вас теперь ни одного видео не прапущу смотреть,как всегда на высоте дай Бог Вам здаров'я....👍👏🏻

ty for sharing ur experience.
Thank you Mr tevz for good job 👍👍
Very. Youse. Full.. Video. Thanks. Boss. Have. A. Nice. Day. Thank. S
👍Maestro thank you very much for the video
Thanks for you videos. I love the Candle technic !
Waoooooh amazing ❤️.
Sir you are the best.
Thank you so much 😀
Super vidéo comme d'habitude merci pour ton partage 👍👍
Magnifique, sans camera thermique,sans bombe de froid c'est du grand art.
Im always waiting for your next video
Thanks
Great video like always
Thank you Tevz
My pleasure!
NICE repair. Thanks friend.

seguimos aprendiendo, saludos.
Yes once i removed one shorted cap from laptop it works great for 15 years.
Removing one of the capacitors doesn't matter. Many capacitors are connected to the line.
Thank you for this video !

I dont use an insolated transformer. Oled TV isn't yet around in my area.
Good video thanks sir
I have use same trick for shortcircuit remove.❤🙏
Perfect. Do you use any schematics? How do you know it is a filter or a PFC??
Thanks!
Greetings from Sweden.
U are great
Very good video sir
Good master
Nice sir
thanks 👍👍👍

It is a tantalum capacitor.
@tevzTVTevatronics thank you sir. Do you know it's value? What's Farad? What's Voltage? Thanks again.
@@lightshine6044 I dont know, not in my mind to note it sorry.
Thanks. Can you tell me the bran name & part number of WHITE PASTE that you put on between FET & Heat sink? Thank you again for your answer so far.
@@lightshine6044 heat sink compound, it's a Chinese brand, and it is written in Chinese characters.
Thank you.
👍
замечательно!
bien trouver avec la bougie moi j ai la caméra thermique ses plus facile merci pour la vidéo
A thermal camera is too expensive.
👍👍👍👍👍👍👍👍❤❤❤❤❤❤
Hi bro yr the best ..but is it possible to change the lcd direct gold strips when it's burnt?
If you can solder it is the question.
Thanks again...sir
Respect my master
Sir please make video on adjustable 6Amp power supply that you make.
Someday soon

Good day Tevz looking for a lg65uf7700-sa mainboard for a reasonable price do you have one?
Sorry, I dont have.
Nice
Hi engineer
Why did you doubt the mainboard after the instability of the voltage in the power board was determined?
If the voltages on the power board are not correct
good
Is there a timber wotkshop nearby?
What pin on the connector was the 12.8v?
12.8 is the 13 volts, no problem with it and it is the main power supply ouput.
Thank you Tevz. What pin number was that on connector?
Also please ,what does IT stand for on connector diagram.
Wouldn't it be better if you checked and compared the main board before and after removing the main board
Why you are not replying me on Facebook
Well done
Hi tevz and hi tevz’s family.mr.tevz do you have Email address?
