@javeeth786 first verify for us that your TV is a Sony KLV-32R412C. The light Grey screen only means that your backlight functions. If you have no video, you first have to make sure that you do not have any video output at all. Try every input source that your TV has. If it still does not have a video, it is possible that this is a mainboard issue or (worst case) a panel issue. Unplug your TV, remove the power cord. Then remove the back cover. Now take a look at t all the boards. Check for anything odd like burned, or missing component setrc. Post some clear, large pictures of all of your boards with your Question. That way we can see what you see and hopefully guide you further. 기존 질문에 이미지 추가하기
