A customer mentioned that their TV had no sound and no image. When the power was turned on, there was a backlight but no display. The screen showed no characters. After connecting the cover directly to the logic board, the first test showed 12V was normal, as well as 3.3V and 1.8V. However, VGH, VDD, VGL, COM FB, and HVDD all read 0V. When I touched the boost chip, it was hot, so I immediately suspected the logic board was faulty. I bought a replacement from TB, installed it, and was left in shock—like a child playing with lanterns during the Lantern Festival. My heart felt like it was being cut open. Was this bad luck? It felt like the screen had hung up again, and I could see hundreds of flying fish once more. After checking through the steps, it seemed like the issue might be resolved. But I took a moment to calm down and think. Maybe the LCD panel wasn't properly connected to the two printed boards. There were a few components involved, and perhaps there was an unexpected discovery. I decided to take the following actions, which ended up being the right choice.
