I have a Orion TV sled 4668 LED LCD Dhtv that the picture looks blurry

@merilynflor blurry pictures are almost exclusively caused by a a bad t-con but can also be caused by a bad panel and bad main board. Remove the back cover from your TV and post some good pictures of your boards etc. That way we can see what you see. Adding images to an existing question If nothing else I’d replace the T-con board first. We need to see your boards since some off brand TV’s use a combination board :-)
