I turned it on and the screen comes on, i am sorry im unsure how to test it. if you know how i could test it please let me know! There is still some plastic over the screen from the manufacturer. It has sat for an unknown amount of time, unsure if it needs anything done to it. Comes as pictured. Please feel free to message me with any questions! I am selling this item as is with no returns so be sure you know what you're getting.
