Facing TV Problems? Ask a TV Technician.
Hello, Sorry you're having problems.
Samsung Smart Hub is simply a feature on a Samsung Smart TV or Blu Ray player - it's not a device.
So that said, are you talking about a TV here? If so get me the model number off of the back of the TV.
Also, are you trying to say that the "TV" itself shows no signs of power (no power light, etc.)?
I need you to elaborate on exactly what you're referring to here today.
