I have the same problem with my led tv samsung 32c6700
No video but sound is working
I own Samsung - 40" LED TV (Model Number: UN40C5000QFXZA) and bought it just one month ago. Today, when i switched it on, there was no picture regardless. Nothing, just a faint light on the
screen, however the sound is working. Even TV MENU is not displaying on screen and when i change source a little light goes on the screen, that's it. I have created a service request with Samsung.
Does anybody come across similar problem? I am thinking to return the TV since it is only one month and have little time to return it? What is forum suggestions ?
