The no video issue can be related to a bad backlight inverter circuitry. A simple check for that would be to darken the room and turn the TV on. Turn the TV to a channel where you can hear the sound. Next, use a flashlight and shine the beam at an angle against the screen. Do that in a darkened room. See if you can make out shadows or shapes. If you do, then it is your backlight that has failed.
If you do not see anything, unplug your set and remove the back cover. Then visually check the boards for any obvious damaged components. Check all the wiring and unplug the wires and plug them back in, make sure they are properly seated. Post some images of all of your boards with your question. Use this guide 기존 질문에 이미지 추가하기 for that so we can see what you see. This could be as simple as a bad T-con board to as complexz as a bad panel. However, my money is on a failed backlight :-)
