Rendering Problem

I've had a problem with certain models not loading properly. Like I spent coins on those TV's and half of them don't show the picture on the screen. Some do, some don't. And models I've used dozens of times just aren't loading properly and it makes no sense. That's on top of the renders not working properly.
