Screen going black, sound works, green light blinking

Angel Outlaw  when the screen goes black shine a flashlight beam at an angle against the screen and see if you can still make out the picture. If so it’s your backlight. If you cannot then it is time to remove the back from your TV and check the boards for any obvious damage. Tehn measure the output from the power board to the main board ( values should be printed on the boards). Also, measure the values on the LED backlight connectors. It could prove helpful if you post some good pictures of your boards and interconnect cables with your question. that way we can see what you see. Adicionar imagens a uma pergunta já existente
