My tv wont turn on

When I turn on my televison, the image does not appear, all that you can hear is the "click" of the television turning on and off. This process goes on and on, and the image never appears. How do I get my television to turn on, and the clicking to stop?

    I'm getting the same issue, only we would also find the tv turned itself on, seemingly at random, every thirty minutes to an hour. I've noticed that it has something to do with the devices that are plugged into it. I unplugged the PS3 and Bluray player and noticed that the issue stopped.

I have a Samsung KS8000 -The TV goes to standby mode and turns on automatically but no image, keeps repeating this process.

Take it to a Samsung service centre unless you are a television engineer. Sounds like a power board problem, but could be many things.

Red light stays on

First before a reset the set must turn on, if the set just sits there with the red LED on you have further problems, so does the set display anything?
