@reyboob verify for us that you TV is a 37LF65. If you are absolutely certain you do have a backlight then the issue is most likely either the T-con board or the main board. You do want to go ahead and post some pictures of all of your boards with your question. That way we can see what you see. Use this guide Adding images to an existing question for that. If you have a multimeter, check the fuse on the t-con board for continuity and power. Let us know what you get.
