Power clicking on and off

Leann Martin what is the exact model number for your TV? Unplug it and unplug everything that plugs into it (Coax, Sat box, Cable box etc. as well) Then unplug the TV. Hold the power button down for about one minute. After that plug in one video source (preferable a local source like DVD, BR Game console etc. ) and plug the TV in. Then turn it on. Let us know what you get. This could be a power board as well as a main board issue. You would have to remove the back cover from your TV and post some good images of your board and the payout with your QUESTION. That way we can see what you see. 在已经存在的问题里加入图片
