MacBook Pro 15" A1707 - Radeon Pro 555 - i7 - 16GB RAM. This MacBook Pro turns on but the display is not working. The display turns on very rarely. The screen has flickered on maybe 3-4 times since it stopped working. I used an external monitor to take photos of the specs. Everything functions except the display. It has the upgraded Radeon Pro 555 graphics. The is a small crack in the lower screen bezel. This happened after the screen stopped lighting up and is not the cause of the screen issue. I believe it has the Flex-Gate issue which requires a screen cable replacement. I signed out of my iCloud account and it is not locked in any way. There are many scratches and dings. Please look at the photos.
