Loud pop out sound and tv went dead

@griseldaro96114 this sounds pretty much like component (most likely a blown up MOSFET or another IC) on your power board that has gone up in smoke. Unplug your TV, remove the back cover. Visually check all the boards for any odd/burned/charred or even missing component. Take a couple of really good pictures of those boards. Post those pictures with your Question. that way we can see what you see and hopefully we can give you enough advice so you can get your TV back to work.
