Taking apart a Samsung TV UN65RU7200F

I'm sorry its not a professional video, just thought I'd video it as i was taking it apart in real time. I'm taking apart our Samsung UN65RU7200F TV because it won't turn on. The red power light will not come on. I tested the power cord and tried a different outlet, so I'm taking it apart because I want to see what it looks like and would like to fix it. I will post another video of taking the power board out because I'm ordering a new one to see if that fixes it. This TV has a power board and video board as you will see.
