The technician is excellent and demonstrates excellent disassembly skills. As someone with some experience in this field, I understand how difficult it is with TVs of this size.
However, the logic behind the sequence of actions raises questions. Initially, she performs a preliminary diagnosis by simply connecting the power supply and attempting to turn on the device. Seeing nothing on the screen, she obviously concludes that the backlight is faulty, which prompts further disassembly. In my opinion, it's strange that she didn't connect a signal source and/or didn't attempt to check the user interface output to the matrix using a flashlight. The problem could lie in the power supply or even the processor board. If so, then a full disassembly might not be necessary. Okay, let's say the viewer can't see it in the video, but she sees that the TV turns on and sends the appropriate signals somewhere. She disassembles everything and gets to the backlight strip. How does she know that the strip itself is at fault? She doesn't check for backlight voltage or test the LED strip itself. Yes, a burned-out LED is probably the most likely scenario, but others are also possible. If she performed all the diagnostics described, it's strange that it's not shown in the video.
The conclusion from what was said is that most likely, this woman isn't the only one (and perhaps not the only one) repairing this TV. At the very least, the diagnostics were performed by someone else.
Incidentally, the actual results of this repair aren't shown in the video—a glowing backlight doesn't necessarily mean a working TV if the problem wasn't solely in the backlight.
Anyway, thanks for the video. I watched it with interest.

Hello, beautiful. Good morning. What a great repair you achieved. Greetings, Hector from Argentina.

Cool! 🆒 I would have tried to on/off button on the TV after the remote didn’t work. Perhaps there is an issue with the system. The TV still may power up☺️. Great video thanks!!

Love watching her work!  Definitely knows what she's doing 👍👍👍👍

Be careful dealing like you it's very nice job

Excellent work, good.👍👍👍

Hello pretty, thank you very much for your valuable lessons.... You're adorable!! ❤❤❤❤❤❤❤❤❤❤❤

Nice clean work place.

It looks like you changed the backlighting on a Hi-Sense. They are tricky because they use adhesive to mount the light bar. Great job.🎉

Thank you for the fix

It only takes professional care for that. ❤😊

Very good 👍👍👍💙🇮🇷

Hello, i am from Indonesia

Super travail

Eu até tinha vergonha de ter uma TV toda suja em casa e a levar assim para consertar

Этой модели не может быть 10 лет, максимум 6 лет. Посмотрите шильдик на задней стенке, где указана модель, там будет написан год и месяц выпуска. Похоже, это только первая часть видео по ремонту данного телевизора. Кроме замены планки подсветки, необходимо установить новые отражатель и дефлектор, взамен деформированных родных. Затем увеличить резистор в драйвере подсветки, для уменьшения тока. Аккуратно антистатической метёлочкой убрать все налипшие пылинки, аккуратно установить на место матрицу. Включить белое поле, проверить на отсутствие соринок и отпечатков пальцев, так как работаете не аккуратно, без перчаток и присосок. И только тогда можно аккуратно защёлкивать заднюю стенку, внимательно осматривая рамку, чтобы не треснула матрица. У Самсунгов всё очень хрупкое.
