Black screen but sound and backlight working help !	Can't Post

Hi guys

Recently got a broken TV that is showing no video however the audio and backlight are both working. I have noticed that the LCD screen has some deep scratches to the point where colours are shining through a little bit in some areas. I think this is because the scratches are so deep they have scratched down to the black polarizer sheet a tiny bit but I'm not sure. Does this mean the LCD panel is bad ? As I say some scratches but no cracks that I can see and other than that the screen looks pretty good. So far I have disconnected the T-con board to see if that changes anything but it still showed the same issue but I havent replaced any parts yet. The TV is a Samsung UE55F6670SB.

Any suggestions would be great thanks guys.

If you need parts for your television, please try this guy on Ebay; he also has a new website for diagnosing televisions that anyone can understand, so take a look.

Thank you for the reply but I have just checked the site you mentioned and there is nothing about the particular issue I have.
