@osmanuel you did not tell us what it does do. Any indication that it turns on? If so the issue could be a bad power board, bad main board, bad T-con board and finally a bad panel. You will have to remove the rear cover from your TV and take a look at the boards. Check for obvious damaged components. Post some good pictures of your boards with your QUESTION. That way we can see what you see. Adding images to an existing question
You will also need a multimeter to measure the output from your power board to the main board since the number one subject here would be the main board.

Hi @osmanuel
Here’s the service manual for the TV. Be patient when trying to download the file, as it takes a little while to go from processing to download, after you have passed the security check and clicked on Go to Download, below the document preview box.
Here’s the No Power troubleshooting flowchart, taken from the manual, which may be a good place to start to find out what the problem is.

If the power light blinks 2 or 3 times, you may need to reflow the CPU chip. Details at https://lab.remaker.com/2020/11/lg-47lw5..., and also on other iFixit posts about the 47LW5600.
