[SỬA] Sony KDL-43W750E, 6 nhịp, Không phải LED! Bật mí điện áp chân IC LED DRIVER!

In this video, I'm repairing a KDL-43W750E with a red LED flashing 6 times. It's a bit unfortunate that the LED wasn't broken, which would have resulted in a higher repair cost. But that's okay, the fault is on the board; although not overly complex, it requires careful attention to ensure longevity. Also, towards the end of the video, you'll see the voltage at the pins of the LED driver IC for this model, the BD9423EVF, while it's operating normally.
