The screen goes black?

candyferguson72  you did not tell us if you continue to have sound. If you do then once the screen is dark, shine a flashlight at an angle against the screen (in a darkened room) to determine if you can still make out shadows, shapes etc. If so it is your backlight. If not then you need to check your main board and your power board. First make sure that the power board supplies proper voltages to the main board. Then check the LED connector and see what the voltages are on it. If you have no power to the LED connectors it is your main board not enabling the backlight. If you have power to the LED connector but no backlight, it’s your Backlight LED arrays. Post some images of all of your your boards so we can see what you see
