If it was the LEDs, then you should still have some working. My first thought would be the LED driver circuits.

Best of luck.

Take it to a TV repairer, preferably an LG authorised repairer. It is highly unlikely it is the power supply. There is nothing you can do to fix this yourself.

You have one component on the board that is faulty. Here is a cautionary tale. Have you done the course?

Here is a question that we see often.
Question:

I've replaced everything in my television because it previously had a black screen with no lighting. Now it doesn't turn on at all and all I have is audio. What could be the cause ?

So your television stops working properly and you think it must be easy to fix, because you can buy boards on eBay, and you can watch YouTube videos. So you make a decision, you buy a board and you fit it, but the television still doesn't work! This is a classic case of the 'let's try replacing this' method of television repair and illustrates why it is a bad idea. It doesn't work for a number of reasons. To correctly diagnose issues, you need to know every board, what is does and every component on the board. You need to know which part has failed, replace the component, or replace the board. The parts you purchased off eBay were probably out of scrapped sets and not tested. The part your put in was dead when you put it in, so you just moved on to another guess at what might be the cause and replace a board that is fine. And so it goes on, you change all the boards and it still doesn't work. Did you notice the large print that says 'No Refunds, NO Returns'. This is to stop you sending your old one back and saying it didn't work, but the unscrupulous use it as an excuse to get money for selling items that may not work! The course to be a television engineer is 2 years full time education, take it to someone that knows how to diagnose and fix. It is by far the cheapest option. The part that failed might be a 20 cents fuse diode hard soldered to a board. They will charge you $2 parts and an hours labour.
