Niebieski obraz LED TV LG - WYMIANA PODŚWIETLENIA backlight - WebOS 49UH6507 UHD serwis naprawa

Hello! Another video about TVs – this time modern ones. We're back to the topic of LED backlights. This time, I'll be taking on a professional backlight repair. I received a 49" LG Smart TV 4K UHD WebOS from family. The backlight was broken, and instead of glowing white, it glowed blue. This is a common problem; such cases do occur. I'll talk a little about the TV's construction and repairs. I'm removing the screen to access the backlight. I'll also use a professional backlight tester. I'd like to thank Sontronic for providing the test stand and tools. I highly recommend Sony Service and wish everyone all the best! Enjoy!
