During use, there was a sudden loud noise, but everything was fine. Then the phenomenon shown in the picture appeared, from left to right, it was black. If you look closely, it still shows that the brightness is gone.

Isn't it that the capacitor on the circuit board exploded?

I just want to ask the big guys to take a look. It hasn't been opened yet. It's a TV. Xiaomi TV 3

I guess it exploded and then the brightness went out as shown above.

The sealing is OK. I didn't smell it, but something is broken. Xiaomi TV 3

There's something wrong with the backlight.

The problem of the backlight panel is not difficult to solve. When disassembling the machine, first look for the exploded component. The capacitor is most likely to be the cause. Be sure to measure the power supply voltage first and analyze the cause of the component damage.

Are you going to take it for warranty repair or do the repair yourself?

I guess the official has not released any information on this matter, you can consult after-sales.

Teacher, I just want to take it apart and replace the device (capacitor) that is probably blown.

Do it yourself; the official one is too bad, they told me to change the TV directly

Is the backlight the row of LEDs below?

Some have a dedicated backlight panel to ensure uniform backlighting.

Is it the backlight of the TV? It is obviously lit by the light from the right side, just like a spotlight. The left side is not turned on.

Be sure to measure the voltage first to avoid problems caused by power supply abnormalities.

After the board is finished, take it apart and have a look.

The operating temperature of the display is not high, it should be the quality of the capacitor is not good
