Hello.How many times does the red light flash?

When you hit power, take a flashlight to the screen and see if there is a dim picture. You gave very little data to what happens. Lgs flash 3 times red when you turn them on

Blink Normal . No sound or anything, I have tried removing mainboard. But nothing happens no backlight. Then I remove the panel and I tried to test all the leds one by one. They look ok. Should I try a replacement led?

You did a lot of work lol. I have had similar problems with a model like this. LEDs tested fine, I replaced them like an idiot, they still tested fine. When I turned on the TV though, If I used a flashlight I could see a picture. My issue was the main board

Take a flashlight to the TV after you hit power does it show a very dim picture? You have to get very close and move the light all around

Red led blinks 3 times. In the power board there us a green led that blinks 5 times

There's your clue, 5 blinks most invariably mainboard issue.
