In this video I take on a full teardown of my main smart TV, the Sony Bravia KD-65X750H, after it developed a backlight issue. It started with the dreaded blinking red LED — six blinks on power up — and no picture. Using a new LED tester I picked up online, I went step-by-step through the diagnosis and found multiple bad LEDs, including one completely dead strip.
I go through removing the back cover, accessing the power supply, testing the backlight voltage, and checking each individual LED strip. From there, I disassemble the panel to reach the LED arrays, swap out dead LEDs using spare parts and a torch/soldering setup, and share tips for handling fragile diffusers and avoiding common mistakes.
Once everything was reassembled, I powered it back on for the moment of truth — and while it didn’t fully work on the first try, I learned a lot that I’m sharing here to help anyone attempting the same fix. I’ll be revisiting this repair in the future when I have more time, but hopefully this video gives you a clear look at the process, the tools I used, and what to watch out for.
