'''++Krishnan S++''' you’ll have to remove the back from your TV first. Then measure the power supply outputs. Let us know what model your TV is and what voltages you get when you check your board.

Once you have the back open take some good pictures of all of the boards so that we can see what you see. [guide|21499]
