TV KEN BROWN model KB - 39 - 2222 - LED without image turns on and there is hardly any clarity and does nothing else. With the control on and off, it has no sound at all. WHAT IF ON AN EXTREME OF THE SCREEN OR IS ON THE SIDE OF THE SIDE WHERE THE HOT ENERGY IS CONNECTED ENOUGH OF THAT EXTREME ONLY

You would have to bypass the source ... to rule out if there is any tension from there that goes wrong with the backlight ... that way you discard to see if it is the source ... most likely you will have problems in the Main. ..but just in case, discard the source and backlight with that method ..
