Why does the LCD turns off after it started to turn on

Olevia 237 s12 LCD TV is on but the backlight goes off and then nothing on the screen. Even lighted with a flashlight and I see de O logo for a second then nothing. Any help?

I have taken the power supply board and replaced a blown capacitor. I've replaced and still doing the same. haven't been opened gain so couldn't see if its blown again. Any help?

Edgardo, open it up again and most likely you will find the same caps gone. Bad PSU design. Up the capacitance of the caps and see if installing a heatsink will be possible. Post some images of the damage with your question so we can see what you see.
