Restoring is not the solution. Even if you could do it, there is no need. Clean the screen connectors with 90%+ isopropyl alcohol and a cotton swab. Don’t let alcohol touch the screen. Then reseat the cables, and reboot. If it doesn’t help like I suspect (since you have backlight as you said), try a new screen on. If a known good screen still doesn’t show an image, consider this: there are 2 screen connectors, one on the left and one on the right. The one on the right is for the LCD part of the screen assembly. Examine that connector, and especially south of that connector. There is a line of tiny components. Is anything missing, torn, damaged? That might be the cause at this point.
