Just plug in a weak blue LED | Loosen the inverter board connector if the LED turns red, the defect is on the inverter board, in my case tsound was no shorted MOSFET | As I had another board and in a rush to save time I replaced the board, but this way it gives you a guide to know which board the defect is on. | Ariel Santos |

Without 15v voltage | Smd capacitor that is from pin 4 of ic 201(bd9763fmv) to gnd in short. this capacitor is on the y-sus board. This board generates 15v through the vs voltage. It uses this voltage and also sends it to the z-sus board. Without it tsound is no image. . | As the capacitor was shorted, I didn't have its value. But the manμFacturer's datasheet recommends a 1 microfarad capacitor. I used a 1 micro/25 volt electrolytic capacitor. smd resistors and capacitors in addition to the tr201 and an smd diode | JOSE CARLOS |

TV turns on, appears immediately and then turns off. When the TV is open, tsound is a noise from the LED power oscillator. | This TV uses an LED bar on the side of the screen, a total of 32 LEDs wsound the circuit powers them, divided in half, 16 for each side. | I did several tests on the board and didn't find a defect, and I could tell that it was being forced, I tested by adding another LED to each circuit, so it turned off even faster and the noise increased. So I removed an original LED on each side, leaving 30 LEDs in total, and the circuit started working normally again without the excess noise. | Margutek.BVA |

Receives normal on and off function, power supply voltages ok by connecting directly (I use a 1k resistor on the pwon at 5v, 12v appears then just touch 5v on the pwrdim and 24 appears), another way is to put a strong flashlight on the screen and keep pressing the menu, if you see it could be the same problem. | I replaced 2 mosfets (tsound are 4) of the inverter, in my case short, fdd8447l | Macro Eletrônica | |
