@vadertaz “if the room is dark enough you can see images on the screen.” indicates bad LED backlight. This could be related to the power board as well as the LED backlight strips. Measure the voltage from the power board to the LED and let us know what that voltage is. If the voltage is to low check the main board to ensure you have around 3.3V on the backlight enable. If you do it is your power board. If the voltage is high on the LED connector thanthen it is your backlight strips.
