Thank you for viewing. The included accessory is the power cable. It was working without any problems until recently. I have checked, and I believe there are no dead pixels. There are no pets or smoking in the environment. There is a feeling of use on the exterior, but no major damage is visible. Please understand that this is a used item. Thank you for your consideration.
