Removing power board on Samsung UN65RU7200F TV

I'm sorry it is not a professional video. I just thought I'd video it so maybe it would help someone else like myself. I'm removing the power board so I can replace it. The TV won't power on and the red power light does not come on. I've tested the power cord and the outlet and they are good. I've ordered a replacement power board and will post another video of installing it if it works.
