I have this Samsung tv un55tu700df and one day the thing will be working fine and the next day or a few hours later the screen will just be dark like someone turned the light off, I can still hear sound and see the picture but it's just dark. Any known solution for this outside of buying a new tv
If this does not help I recommend letting a service technician have a look. As we would like to gather additional information and look at this from a case by case basis please provide the full model code and the serial number of the device as well as your best contact phone number, name, and email.
