Screen for sale, nothing wrong with it, complete and only God is complete. It works with satellite receiver if you have one, or if your children play PlayStation, you can connect it for them, or in a shop, or anything. But when you turn it off or turn the volume up or down, it says it needs to be locked, it needs formatting, I don't know what it needs. The screen is in front of you, the HD ports are intact and everything is intact. Whoever wants to contact me, this is my number ( Phone number appears when clicking the contact button ) . My price is 250, the minimum. Regarding Hz, it's 60 Hertz, and the inches are from 70 to 80 or less because it's not written on it.
